Launch of a second modernized Compass (Beidou 2) satellite on April 14 — this one a geostationary spacecraft — marks the return of China to its GNSS launch program two years after the initial venture into space.

Designated Compass G2 — reflecting the geostationary nature of its intended orbital position about 22,300 miles above the equator, the satellite lifted off at 16:16 UTC aboard a Long March 3C rocket from the Xichang launch base in southwestern China’s Sichuan province, according to China’s state news agency Xinhua.

Air Force Secures ITU Filing with GPS L5 Signal Transmission

Time Series and Power Spectrum of the L5 Demonstration Signal

The GPS IIR-20(M) satellite successfully transmitted for the first time a GPS signal in the L5 frequency band today (April 10), according to the U.S. Air Force operators of the Global Positioning System. L5, the third civil GPS signal, will eventually support safety-of-life applications for aviation and provide improved availability and accuracy to users.

GPS L5 Signal Goes on the Air April 10

Stanford “Big Dish” Antenna

U.S. Air Force officials are moving quickly to turn on the new civil GPS L5 signal after lengthy delays due to technical problems had brought the program close to an International Telecommunications Union (ITU) deadline for transmitting on the frequency.

The Air Force plans to begin transmitting the signal at 5 a.m. (PDT) on April 10 using the Block II R-20(M) satellite launched March 24. An L5 signal demonstration is planned the same day, organized by the GPS Wing and SRI International. The L5 spectrum will be received and plotted at the SRI’s 150-foot “big dish” antenna facility in the hills over looking Stanford University, California.
