Really Rocket Science

 

 

Satnews is reporting EMC Satcom was able to fit an STM-1 circuit into a 72-MHz transponder. That's just awesome...

EMC Satcom Technologies GmbH established a new landmark in satellite link optimization by achieving a symmetrical 155/155Mbps circuit inside a single transponder and, in tur, liberating a full 72MHz transponder. The existing STM-1 in Asia-Pacific was using a 72MHz transponder of the outbound carrier 155Mbps and another 72MHz for the inbound carrier 155Mbps. By placing EMC Satcom’s NRS Bandwidth Booster at each end of the link, a full 72MHz has been cancelled, allowing the existing symmetrical 155/155Mbps STM-1 to operate within one transponder only.

That's right, it's patented, too (United States Patent 7,522,877). The abstract...

The reduction of echo noise in satellite communications includes receiving an aggregate signal from multiple remote stations, where the aggregate signal includes a transmit signal, whose bandwidth is in the range of 0.1 MHz to 66 MHz, is previously sent from a hub to the multiple receiving stations, computing a scaled, delayed and distorted replica of the transmit signal and using the replica to compensate for satellite transponder nonlinearities and reduce echo noise interference from a received aggregate signal received by the hub from the multiple remote stations.

And Claim 1...

A method for reducing echo noise in satellite communications in which a hub communicates with multiple remote stations via a satellite having a nonlinear satellite transponder, the method comprising the steps of: transmitting a transmit signal from the hub to the multiple remote stations, where the transmit signal contains at least one carrier; providing, at the hub, a replica of the transmit signal to a buffer that provides an integer sample delay; distorting, at the hub, the replica of the transmit signal according to nonlinearities of the satellite transponder to provide a distorted replica of the transmit signal; determining, at the hub, a scaled, fractional-sample time-delayed, frequency-shifted, and attenuated version of the distorted replica of the transmit signal to provide a compensated distorted replica of the transmit signal; and using, at the hub, the compensated distorted replica to represent the nonlinearities of the satellite transponder and reduce echo noise from a received aggregate signal received by the hub from the multiple remote stations via the satellite transponder; wherein the distorting step further comprises applying a block conversion to the transmit signal to form the distorted replica occupying a predetermined frequency range and the determining step further comprises tracking the integer sample closest to a weight vector centroid of an adaptive filter to provide fractional-sample delay of the distorted replica.

 Not something the satellite operators are excited about, as it uses less bandwidth. Further compression is not something they look forward to, hence the interest in 3DTV (and HDTV before that). In this case, the "less bandwidth, more through-put" benefit is for the customer.

The customer is always right.

 

 

The University of Tokyo's Intelligent Space Systems Laboratory (Nakasuka) built and launched a cubesat, 4-in/10-cm square, in 2005. The low-earth orbit spacecraft is now sending out updates via Twitter, all by itself.

 

 

 

The tweets, in Japanese, even feature little twitpics and have assembled over 2,600 followers. Some detail, via Asiajin:

 Nakasuga Lab., the University of Tokyo, introduced a bot account tweeting the real-time state of a satellite which is located in the earth low orbit.   The tweet(@XI-V) keeps us update with parameters like the satellite’s surface temperature, battery voltage and where it is located over of the planet and also shows us still images shooting the planet from the satellite in the space.

As we've blogged before, real-time tweets from space has had human intervention. This is automatic, and that's kinda cool. This information is more than the poor boys at Intelsat have regarding the Galaxy-15 spacecraft. They get no telemetry data at all, but they do have some ranging info and ephemeris data.

As for CubeSat XI-V, a job well done by the rocket scientists at Nakasuka!

Excellent review of Peter Gabriel's performance at Radio City Music Hall last night. "Here Comes The Flood," from his first solo album, was not part of the playlist, but Randy Newman's "I Think It's Going To Rain Today" was. I like his approach, doing all covers on his new "Scratch My Back" album.

Think songwriting, and Nashville comes to mind. It's not called "Music City" for nothing. I'm expecting somebody to write a song on the terrible flooding of the past few days.

NASA's Earth Observatory site has published satellite imagery showing before & after pics...

 ...before, on 29 April 2010...

 

 

 

...and after, on 4 May 2010...

 

 

 Record-breaking rain triggered severe and widespread flooding across Tennessee starting on May 1, 2010. This false color image provides a cloud-free view of the region’s swollen rivers as seen by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite on May 4, 2010. Terra MODIS acquired the lower image on April 29, 2010, just two days before the storm.

The images combine infrared and visible light to increase the contrast between water and land. Water is black or blue, while plant-covered ground is bright green. Bare earth around the Mississippi River is tan, and clouds are pale blue.

A comparison between the two images reveals flooding on nearly every river system. The landscape is marbled blue from countless swollen streams that aren’t normally visible. The Tennessee River and Cumberland Rivers and their tributaries are wider on May 4 than they were on April 29. In the west, the Obion, Forked Deer, and Hatchie Rivers are also notably swollen.

Flooding across middle Tennessee was at record or near-record levels, said the National Weather Service. The Cumberland River crested at 51.86 feet in Nashville on May 3, the river’s highest level since the Cumberland River dam system was built in the early 1960s. Four other Tennessee Rivers also reached record highs, said the National Weather Service. By May 4, when this image was taken, the rivers had started to slowly recede.

 

 

 

We knew this was trouble. Now, Peter de Selding and Fox News report a crisis in the making...

Galaxy 15 stopped responding to ground controllers on April 5. The satellite's manufacturer, Orbital Sciences Corp. of Virginia, has said an intense solar storm in early April may be to blame.

An adrift Intelsat satellite that stopped communicating with its ground controllers last month remains out of control and has begun moving eastward along the geostationary arc, raising the threat of interference with other satellites in its path, Intelsat and other industry officials said.

In what industry officials called an unprecedented event, Intelsat's Galaxy 15 communications satellite has remained fully "on," with its C-band telecommunications payload still functioning even as it has left its assigned orbital slot of 133 degrees west longitude 36,000 kilometers over the equator.

Galaxy 15 stopped responding to ground controllers on April 5. The satellite's manufacturer, Orbital Sciences Corp. of Virginia, has said an intense solar storm in early April may be to blame. It was launched into space in 2005.

The first satellite likely to face signal interference problems from the adrift Galaxy 15 is the AMC-11 C-band satellite owned by SES of Luxembourg and stationed at 131 degrees west, just two degrees away from Galaxy 15's starting position.

Rob Bednarek, chief executive of the SES World Skies division, which operates AMC-11, said Intelsat and SES have been meeting since April 5 to coordinate how to minimize the Galaxy 15 impact on AMC-11's media customers. [Spot satellites from Earth.]

Adrift in space

In an interview Friday, Bednarek said that while it remains unclear whether SES World Skies will be able to avoid a signal interference problem as Galaxy 15 enters the AMC-11 orbital territory, the company has benefited from full disclosure on the part of Intelsat, SES's biggest competitor.

"The cooperation with them really has been very good," Bednarek said. "We all realize that we could be in the same position tomorrow. We are neighbors in space."

Alan Young, chief technology officer at SES World Skies, said the company's best estimate is that Galaxy 15 will enter AMC-11's neighborhood — meaning one-half of one degree distant — May 23. It will continue traveling at its own pace through the AMC-11 slot, exiting on the east around June 7.

Young said the period of May 31 to June 1 is going to be the riskiest time for AMC-11 customers as SES World Skies seeks to maneuver AMC-11 to the maximum extent possible out of the Galaxy 15 track while at the same time maintaining links with the company's AMC-11 customers.

Tobias Nassif, Intelsat's vice president for satellite operations and engineering, said Friday that the company, in concert with Galaxy 15 manufacturer Orbital Sciences Corp. of Dulles, Va., has sent between 150,000 and 200,000 commands to the satellite in the nearly four weeks since the satellite stopped sending or responding to commands.

These communication attempts, the equivalent of mild wake-up calls to return Galaxy 15 to service, have had no effect. As it moved all Galaxy 15 customers onto Galaxy 12, which was pulled into service from another orbital location, Intelsat at first focused on recovering Galaxy 15 to regular service.

Zombie satellites in space

On May 3, Intelsat will play what as of Friday appeared to be its last card by blasting Galaxy 15 with a more powerful signal intended not to salvage the satellite, but to force it into a complete shutdown.

That attempt will last about 30 minutes. It will not be repeated, both because a second attempt is viewed as unnecessary — the treatment works or it does not — and because sending out powerful radio frequency signals carries the risk of interfering with other satellites in the area.

Even if the May 3 action succeeds, Galaxy 15 will remain a problem as it continues to wander the geostationary arc. But it is a problem that satellite operators know how to deal with. Industry experts say there are several dozen spacecraft, sometimes called "zombiesats," that for various reasons were not removed from the geostationary highway before failing completely.

Depending on their position at the time of failure, these satellites tend to migrate toward one of two libration points, at 105 degrees west and 75 degrees east. Figures compiled by XL Insurance of New York, an underwriter of space risks, say that more than 160 satellites are gathered at these two points, which Bednarek described as the orbital equivalent of valleys.

"Unfortunately for us, we were downhill from Galaxy 15 as it rolls toward" the 105 degrees west libration point, Bednarek said.

Satellite signal stealer

Satellites like Galaxy 15 and AMC-11 are so-called "bent-pipe" designs that receive signals from the ground, amplify them on board and redistribute them to customers' ground antennas. Emptied of its customers — except one, the U.S. Federal Aviation Administration, which uses an L-band payload on Galaxy 15 to guide aircraft landings — Galaxy 15 is no longer broadcasting. But its electronics payload is ready to capture and rebroadcast signals it receives that are intended for other spacecraft.

Young said that both SES and Intelsat are fortunate in this case because their two satellites' customers are mainly media companies using fairly large antennas to communicate with the satellites. During the period of maximum danger for AMC-11, SES expects to be able to reroute customer signals to SES-operated teleports with still-larger antennas to maintain communications links.

Nassif said Intelsat and Orbital Sciences have solicited outside opinions from other satellite manufacturers on possible maneuvers that might return Galaxy 15 to control or force it to shut down.

"The fact is that this is the first major anomaly on an Orbital-built satellite," Nassif said. "Other manufacturers have been through problems and might have something to suggest to us."

Because nothing like this has happened before, Intelsat remains uncertain as to when Galaxy 15, as its Earth sensor realizes it is no longer in the desired position, might lose its Earth-pointing capability. That would lead to its solar arrays losing their lock on the sun. Within hours, the satellite's batteries would discharge and the spacecraft would shut down on its own.

While cautioning that the company is revising its most-likely-scenario thinking almost on a daily basis as it gets input from Orbital Sciences and others, Nassif said the current estimate is that Galaxy 15 will lose Earth pointing by late July or early August.

As luck would have it, that timetable would mean the only other satellites in Galaxy 15's C-band frequency that face interference issues are owned by Intelsat.

After it leaves the vicinity of AMC-11, Galaxy 15 is expected to approach Intelsat's Galaxy 13 satellite, at 127 degrees west, around July 13. On July 30, it will enter into the Galaxy 14 satellite's orbital territory at 125 degrees west before heading toward Galaxy 18 at 123 degrees in mid-August.

"We are in regular contact with all our customers of these satellites to keep them apprised of the situation," Nassif said. 

 

 

 

Out on the open interstate, you seldom have trouble receiving satellite radio from Sirius XM. As these roads pass through crowded urban, where your line-of-site with an orbiting spacecraft may impede reception, the company relies on repeaters, usually mounted alongside cell towers, to complete the reception. 18 million or so satellite radio customers are happy when this happens.

Today, the Wall Street Journal reports on a potential crisis for satellite radio:

A Federal Communications Commission plan to expand wireless Internet access is raising the ire of Sirius XM Radio Inc. and its fans, who are concerned the effort to end a 13-year fight may interfere with satellite-radio programming.

The FCC is proposing to make it easier for the winners of a 1997 airwaves auction to use those airwaves for mobile wireless Internet and phone use. Until now, a dispute about power levels and potential interference has meant the companies were limited in how they could use the airwaves they own.

The FCC is scheduled to vote on the proposal in May as part of a broader effort to devote more airwaves for wireless Internet services. A FCC spokeswoman declined to comment on the specifics of the proposal.

Sirius XM lawyers are fighting the plan, arguing in an April 23 filing that allowing wireless providers to use those airwaves for wireless broadband will "fail to protect satellite radio's nearly 19 million subscribers and 35 million listeners from harmful interference."

 Here's an excerpt from a Supplement Comments filing (WT Docket No. 07-293; IB Docket No. 95-91; GEN Docket No. 90-357; RM No. 8610):

Sirius XM has commissioned Dr. Theodore S. Rappaport, P.E., of the Telisite Corporation, who is the William and Bettye Nowlin Chair in Engineering at the University of Texas at Austin and the founding director of the Wireless Networking and Communications Group (WNCG) at the University’s Austin campus, to assess the probabilities of interference to satellite radio service caused by WCS devices operating under the proposed rules that are contained in the Staff Public Notice. This analysis is contained in the attached report entitled “Technical Analysis of the Impact of Adjacent Service Interference to the Sirius XM Satellite Digital Audio Radio Services (SDARS)” and provides some of the clearest evidence yet that the staff’s proposed Part 27 rules would result in crippling interference to satellite radio operations in an unacceptable number of cases. Although retained by Sirius XM to conduct this study, Dr. Rappaport has undertaken this project under the express written conditions that the opinions provided in this study are his own.

 

 

 

We're all for more wireless broadband service, but not at the expense of the quality of satellite radio. The FCC, in its wisdom, will likely favor existing licensees and make sure they're protected.

Let's see if the topic comes up in tomorrow's earnings call.

 

 

 

 

 

 

 

 

 

 

MODIS, MERIS, ASAR, GOES: these orbiting spacecraft and instruments are focused on helping the NOAA figure this mess out. The mess is an oil spill in the Gulf of Mexico, approximately 50 miles offshore, estimated to be spitting out crude oil at a rate of 5,000 barrels per day.

A BP PLC executive told NBC’s "Today" show on Apr. 29 that the oil leak in the Gulf of Mexico could be five times larger than earlier believed. His comment came the day after a controlled burn on part of the oil spill and a third leak was found.

Doug Suttles, chief operating officer of BP Exploration & Production Inc., confirmed what US Coast Guard Rear Adm. Mary Landry first said at a hastily called news conference in a Louisiana command center late Apr. 28 in which she announced a third leak.

Landry estimated 5,000 b/d rather than the 1,000 b/d could be spilling into the gulf. For days, officials have estimated 1,000 b/d was leaking from the Macondo well Transocean Ltd.’s Deepwater Horizon semisubmersible drilled on Mississippi Canyon Block 252 in 4,992 ft of water near Rigel gas field. Deepwater Horizon was working for BP.

An Apr. 20 explosion and fire rocked the semi, leaving 11 crew members missing and presumed dead and injuring 17. A total of 115 people evacuated the rig. On Apr. 22, the semi sank. Cause of the accident remains under investigation.

On Apr. 29, Suttles said the leak could be as high as the USCG's latest estimate. Previously, he had told reporters that it’s difficult and imprecise to measure spilled oil. 

Call in the robots!  But it won't be quick. Responders are still figuring out new ways to use Remotely Operated Vehicles (ROVs) to try to trigger the blowout preventer (BOP), a series of valves that sits at the well head.

 

 

 

 What NOAA is doing, as of 28 April 2010...

Current NOAA efforts are focused on: gathering more information about the spill, planning for open water and shoreline remediation, and readying for environmental assessment and response. Natural resource damage assessment (NRDA) activities are now underway. 

• Winds are forecast to become strong (20+ kts) and blow from the southeast starting tomorrow and continuing through the weekend, which will continue to push surface oil towards shore
• NOAA oil-spill trajectory analyses indicate that oil continues to move towards shore.
• 100,000’ of oil-containment booms (or floating barriers) have been deployed as a precaution to protect sensitive areas in the Louisiana area.
• The effects of oil on sensitive habitats and shorelines in four states (LA, MS, AL, and FL) are being evaluated should oil from the incident make landfall in appreciable quantities
• NOAA’s Assessment and Restoration Division is evaluating concerns about potential injuries of oil and dispersants to fishes, human use of fisheries, marine mammals, turtles, and sensitive resources
• Baseline aerial surveys to assess marine life were conducted today with personnel from NOAA’s National Marine Fisheries Service (NMFS), these will continue as needed

 

NOAA Roles: NOAA is a vital part of the massive response effort on the Deepwater Horizon incident.   Many personnel are on scene and many more are engaged remotely, as follows:

Office of Response and Restoration (OR&R)

• Scientific support to the U.S. Coast Guard and Unified Command

Emergency Response Division (ERD)

• Predict where the oil is going and its effects
• Overflight observations and mapping
• Identify resources at risk
• Predict fate (chemical changes) of oil
• Recommend appropriate clean-up methods
• Manage data and information

Assessment and Restoration Division (ARD)

• Plan for assessment of injuries to natural resources
• Coordinate with state and federal trustees
• Implement sampling plans

National Weather Service

• Incident weather forecasts including marine and aviation

National Environmental Satellite, Data, and Information Service (NESDIS)

• Experimental imagery for spill trajectory forecasts

National Marine Fisheries Service (NMFS)

• Issues related to marine mammals, sea turtles, and fishery resources

National Ocean Service

• Public Affairs support to Joint Information Center

Yes, Philadelphia. The hometown of W.C. Fields, who was alleged to have said "Philadelphia, wonderful town, spent a week there one night," is one of four cities to have the FAA's NextGen system installed. The others are Houston, Louisville and Juneau. The system does it all: navigation, surveillance, and communication.

Of course, they use satellite technology.  The Philadelphia Inquirer did a nice piece on it yesterday:

"Philadelphia is a pioneer site," said Federal Aviation Administration vice president Victoria Cox, announcing that Philadelphia controllers now have the capability to track planes equipped with the technology, known as Automatic Dependent Surveillance Broadcast, or ADS-B.

It's part of a nationwide aviation overhaul - called Next Generation, or NextGen - that the FAA hopes will be largely operational by 2018.

By 2020, all aircraft flying in U.S. airspace must have the ADS-B devices in their cockpits.

Philadelphia is a demonstration site because United Parcel Service is here and has equipped 100 aircraft with satellite-technology. US Airways Group Inc. is in the process of equipping some of its planes, the FAA said.

Philadelphia controllers also use a computer system, called STARS, that takes information, including the ADS-B signals, and translates it to the screens controllers look at.

In addition, Philadelphia was selected to get some of the first satellite-surveillance radios because of its location in congested East Coast air space. The other test sites are Louisville, Ky., where UPS is based; Houston; and Juneau, Alaska.

Seven ground radios - each about the size of two refrigerators - have been installed around Philadelphia, including two on airport property. They will be part of a network of 813 radios by 2013, the FAA said.

Once airplanes get specialized GPS devices in cockpits, pilots will transmit via satellite to ground radios, which will bounce information to control towers. Controllers, in turn, will transmit to the radios, which will broadcast up to the cockpit.

The new technology will allow pilots, for the first time, to see what controllers see: other aircraft in the sky around them, bad weather and terrain, and information such as temporary flight restrictions.

 Need more detail? Check out the FAA's NextGen Implementation Plan (84-page PDF). There are basically five elements to this system:

1. Automatic dependent surveillance-broadcast (ADS-B). ADS-B will use the Global Positioning System (GPS) satellite signals to provide air traffic controllers and pilots with much more accurate information that will help to keep aircraft safely separated in the sky and on runways. Aircraft transponders receive GPS signals and use them to determine the aircraft's precise position in the sky. This and other data is then broadcast to other aircraft and air traffic control. Once fully established, both pilots and air traffic controllers will, for the first time, see the same real-time display of air traffic, substantially improving safety. The FAA will mandate the avionics necessary for implementing ADS-B.
2. System Wide Information Management (SWIM). SWIM will provide a single infrastructure and information management system to deliver high quality, timely data to many users and applications. By reducing the number and types of interfaces and systems, SWIM will reduce data redundancy and better facilitate multi-user information sharing. SWIM will also enable new modes of decision making as information is more easily accessed.
3. Next Generation Data Communications. Current communications between aircrew and air traffic control, and between air traffic controllers, are largely realised through voice communications. Initially, the introduction of data communications will provide an additional means of two-way communication for air traffic control clearances, instructions, advisories, flight crew requests and reports. With the majority of aircraft data link equipped, the exchange of routine controller-pilot messages and clearances via data link will enable controllers to handle more traffic. This will improve air traffic controller productivity, enhancing capacity and safety.
4. Next Generation Network Enabled Weather (NNEW). Seventy percent of NAS delays are attributed to weather every year. The goal of NNEW is to cut weather-related delays at least in half. Tens of thousands of global weather observations and sensor reports from ground-, airborne- and space-based sources will fuse into a single national weather information system, updated in real time. NNEW will provide a common weather picture across the national airspace system, and enable better air transportation decision making.
5. NAS Voice Switch (NVS). There are currently seventeen different voice switching systems in the NAS, some in use for more than twenty years. NVS will replace these systems with a single air/ground and ground/ground voice communications system. 

Yeah, there's a video...

This Mini outfitted with a mobile antenna is pretty cool, although it may not be as practical as the "command vehicle" put together by CAMMS.

CAMMS™ (Command Anywhere Media Management System) was developed to enable a totally secure, scalable mobile mesh (ad hoc) network and provide the necessary tools for Command Anywhere.

The CAMMS™ mobile mesh software program is a patent pending Windows-based program, which provides the foundation for an ad hoc, self-forming / self-healing wireless mobile mesh network.   It provides interoperability and allows real time communications with any others users in the mesh.

Mobile mesh (ad hoc) networks offer many advantages over other types of communications networks.  Chief among these is the ability of the mesh to function independently of a land-based infrastructure.

When communication is linked solely to a land-based infrastructure an acute vulnerability exists.  By utilizing a mesh, the network infrastructure becomes decentralized, avoiding a central point of failure and control.  Command can be located anywhere with hand off from first responder to others when required instantly.

The CAMMS™ mobile mesh software does not require servers or fixed access points (FAP’s) and is compatible with existing mesh AP's.  The software may be purchased separately to maximize existing communications systems or as part of complete interoperable communications solution that includes software and AP.
