China Succeeds with Dual BeiDou-2 Compass Satellite Launch

Two Beidou-2 MEO satellites go up on a Long March rocket

China successfully launched two Compass satellites into space at 4:50 a.m. Beijing Time on Monday, April 30 (20:50 UTC, April 29).

Designated Compass M3 and M4, these are the 12th and 13th of its second-generation Beidou-2 spacecraft to reach orbit and the second and third middle-Earth-orbiting (MEO) spacecraft launched by China’s GNSS program.

An emphasis on quality assurance in system engineering and components in the first GPS III satellite now under development has driven projected costs up in the program above the budgeted amount, leading the U.S. Air Force to deny a $70 million incentive fee to prime contractor Lockheed Martin.

U.S. Satellite Export Policy Report Retains GPS Restrictions

The Global Positioning System and GPS receivers show up several times as items of special concern in a report to Congress submitted Wednesday (April 18, 2012) by the Department of Defense (DoD) and the Department of State. The subject is discussed in an appendix addressing “China’s Space-related Strategic Goals, Capabilities, and Methods for Acquiring Technology.”

China Plans Dual Launches of Compass-BeiDou MEOs

News sources indicate that the first Beidou-2 dual launch will take place in April or possibly May. A Long March 3B rocket will carry two middle Earth orbiting (MEO) satellites (M3 and M4) into orbit.

In addition to being the first dual launch of Compass satellites, this will be the first launch of MEO spacecraft since April 14, 2007, when the Chinese GNSS program put the initial second-generation BeiDou satellite into orbit. So far, Compass M1 is the only MEO satellite in the BeiDou-2 constellation.

GPS Program Budget: A Lot, But Is It Enough?

The details of President Obama’s 2013 budget have been gradually filtering out and, in general, the GPS system and those programs closely linked to satellite navigation, have escaped deep cuts.

On the hardware side the White House has requested $58.2 for GPS IIF satellite procurement. According to Air Force budget documents, the plan is to then wrap up the total IIF procurement of 12 satellites with a request for $77.6 million in FY14 and $7.3 million in FY15.

China Launches 11th Compass/BeiDou-2 Satellite

China successfully launched a satellite into space at 00:12 Beijing Time on February 25 (February 24, 16:12 UTC/GMT), the 11th of the nation’s second-generation Beidou, or Compass, GNSS system.

The satellite, launched from the Xichang Satellite Launch Center in the southwestern Sichuan province, was carried by a Long March-3C carrier rocket into a geosynchronous orbit. It is the fifth geostationary spacecraft in the current BeiDou-2 constellation.
