With little fanfare or prior announcement, China launched another second-generation BeiDou Navigation Satellite System (BDS) satellite last week, the 22nd in the nation’s GNSS program.
The satellite launched from the Xichang Satellite Launch Center in the southwestern province of Sichuan on March 29 local time on board a Long March-3A carrier rocket.
An inclined geosynchronous orbit (IGSO) spacecraft designated Beidou-2 IGSO-6, it is expected to operate at an altitude of about 22,000 miles (35,400 kilometers) with an inclination of about 55 degrees.

While acknowledging the fury over problems with the new GPS ground system, the head of Air Force Space Command told lawmakers this month that finishing the program with the current contractor was the best way forward.
That contactor, Raytheon, is years behind on the Next Generation Operational Control System (OCX), a project whose price tag may now top $4 billion.

As the contractor for the new GPS ground system works its way through a make-or-break 90-day evaluation period, the U.S. Air Force (USAF) is weighing whether it should look at leapfrogging past that program and shifting control of the newest GPS satellites to a new common ground system for Air Force space assets.
The Next-Generation Operational Control System or OCX, currently under development by Raytheon, is essential to integrating the GPS III satellites into the U.S. GNSS constellation and operating them at their full potential.

Representatives of the world’s GNSS providers outlined the current plans and progress of their systems at the 2016 Munich Satellite Navigation Summit in Germany.
BeiDou has entered its transition period from Phase II to Phase III, with test and validation of the next phase with its new signal structures and frequencies taking place through the second half of 2017, said Jun Shen, deputy director for International Research at the China Satellite Navigation Office. In the meantime, “there will be a coexisting of Phase II/III BeiDou signals.

The Indian Space Research Organization (ISRO) announced the successful launch today (March 10, 2016) of the sixth satellite in the Indian Regional Navigation Satellite System (IRNSS).
IRNSS-1F lifted off at 4:01 p.m. IST from the Sriharikota rocket port in Andhra Pradesh on board the Polar Satellite Launch Vehicle (PSLV-C32). The 1,425-kilograpm spacecraft will be placed in geostationary orbit at 32.5 degrees East longitude.
