Surveyor’s Saturday Serendipity: How Satellites Work

A wee bit of Surveyor’s Saturday Serendipity with this older, but interesting, video describes how satellites work:

“Geostationary satellites are positioned one-tenth of the way to the moon (about 36,000 km), but how do they stay there? This video shows how satellites stay in orbit.”

Soyuz Launched With First Two Geopositioning Galileo Satellites

Soyuz Launched With First Two Geopositioning Galileo Satellites

A Soyuz rocket has lifted off on its maiden flight from Europe’s space base in South America, carrying the first two satellites in the Galileo geopositioning system.

The launch — the first by the veteran rocket beyond Russia’s historic bases at Plesetsk and Baikonur — is part of a commercial deal struck in 2003 to extend the range of Arianespace, which markets services from the European Space Agency (ESA) base in Kourou.

LightSquared Video to Debunk Several GPS Interference Myths-Facts or Propaganda?

Yesterday, I published a press release by House Aviation Subcommittee Chairman Tom Petri Rebuts LightSquared Ad in Letter to CEO and another press release where the Defense Department Seeks to Protect GPS Operations Against LightSquared Network.

In summary, Congressman Petri, House Aviation Subcommittee Chairman, disputes the LightSquared arguments that the GPS manufacturers are on the wrong side of this interference issue, and Air Force Gen. William L. Shelton, Commander of Air Force Space Command, told members of the House Armed Services Committee’s Subcommittee on Strategic Forces yesterday that LightSquared’s new terrestrial network has the potential to wreak havoc on GPS systems that are vital to the military.

While doing some followup reading on this subject, I came across a YouTube video produced by LightSquared entitled “Find Out Who is Trying to Block Wireless Innovation in America.”

Facts or LightSquared Propaganda

So, does the LightSquared “Find Out Who is Trying to Block Wireless Innovation in America” video actually debunk several GPS interference myths? Are the statements made facts or are they LightSquared propaganda?

I do not know which side is right or wrong, but clearly one side is wrong, as both make opposing arguments making it crystal clear that only one side is making correct assertions. I’ve provided the video out of fairness to both sides and so that you can make your own decision on this controversial issue.

WASHINGTON, Sept. 16, 2011 – Defense Department officials are raising concerns that a company’s proposed wireless broadband network would cause harmful interference to essential Global Positioning System operations.

LightSquared’s new terrestrial network has the potential to wreak havoc on GPS systems that are vital to the military and used in a host of applications, Teresa Takai, the DOD’s chief information officer, and Air Force Gen. William L. Shelton, commander of Air Force Space Command, told members of the House Armed Services Committee’s Subcommittee on Strategic Forces yesterday.

“GPS is vital to national security and is relied upon by our servicemen and women for a wide array of capabilities,” Takai said in written testimony.

House Aviation Subcommittee Chairman Tom Petri Rebuts LightSquared Ad in Letter to CEO

In a letter to the chairman and CEO of a controversial wireless company, House Aviation Subcommittee Chairman Tom Petri (R-WI) sought to set the record straight Thursday following the company’s ad in the Wall Street Journal the day before.

LightSquared, a wireless broadband company, has been mired in controversy because it plans to use a portion of the radio spectrum adjacent to that used by global positioning system (GPS) satellites and the GPS equipment used in cars, planes, military equipment and elsewhere to help users navigate trips or identify the location of GPS-enabled equipment.  A fully functioning GPS system is critical to ongoing efforts to modernize the nation’s air traffic control system.

Brussels, 7 January 2010

Commission awards major contracts to make Galileo operational early 2014

The European Commission announced today the award of three of the six contracts for the procurement of Galileo’s initial operational capability. The contract for the system support services is awarded to ThalesAleniaSpace of Italy , that for a first order of 14 satellites to OHB System AG of Germany and that for the launch services to Arianespace of France. This will allow the initial deployment and service provision of Europe’s satellite navigation system as of early 2014.

Antonio Tajani, European Commission Vice-President in charge of Transport, said: “With this and the upcoming awards for the remaining procurement packages, we are concluding a critical phase of the Galileo programme. We can now focus on the actual roll-out and demonstrate to European citizens that Europe’s own satellite navigation system is firmly underway”.
