OCX budget Cut Could Slow Program; First IIF Might Launch by May 2010

An increasingly likely $97.4-million cut in the GPS OCX budget for fiscal year 2010 (FY10) would slow down work on modernization of the operational control segment, but the Air Force would try to recoup any reduction in the FY11 budget.

Meanwhile, technical problems that have delayed development of the follow-on generation of Block IIF satellites are largely resolved and a first launch is expected in May 2010.

NOAA, Japan Establish QZSS Ground Station in Guam

Officials from the National Oceanic and Atmospheric Administration and the Japan Aerospace Exploration Agency (JAXA) have unveiled a new ground station in Guam that will track spacecraft from JAXA’s upcoming Quasi-Zenith Satellite System (QZSS).

Designed to work seamlessly with the U.S. Global Positioning System, QZSS is a space-based augmentation system (SBAS) being developed by JAXA to improve navigation satellite coverage over Japan and surrounding areas. The first QZSS satellite is expected to launch in 2010.

Air Force Launches Last GPS Block IIR-M Satellite

GPS IIR-21(M)

The U.S. Air Force successfully launched the last in the series of eight modernized GPS (IIR-M) satellites today (August 17) at 6:35 a.m. (EDT).

Using the Space Launch Complex 17A at Cape Canaveral Air Force Station, Florida, the satellite was carried into space aboard the last of the Air Force’s United Launch Alliance Delta II rockets.

GPS IIR-21(M) will join the constellation of 30 operational satellites on-orbit, assuming a position in plane E, slot 3 and replacing space vehicle number 40 (SVN40). The Air Force expects to set the satellite healthy for navigation users worldwide next month.

Upcoming Block IIR-(21)M Launch Wraps Up Generation of GPS Satellites

The scheduled August 17 launch of GPS satellite IIR-(21)M — also known by its space vehicle number SVN50 — will mark the end of a couple of eras: the final launch of the Lockheed Martin–built replenishment generation (Block IIR) of GPS satellites and the last Air Force launch using the Delta II rocket.

Notably, SVN50 will not have a payload connected to the J2 reserve auxiliary payload port that proved problematical with the L5 demonstration payload on the previous GPS satellite, SVN49, and possibly on other Block IIR/IIRMs.
