Faulty Booster Component May Delay IIR-M Launches; L5 Signal Ready to Go

Faulty Booster Component May Delay IIR-M Launches; L5 Signal Ready to Go

Suspected faulty components in a Delta II rocket are delaying the launch of the final two modernized GPS Block IIR satellites, possibly preventing the early broadcast of an L5 civil signal that faces a 2009 deadline for being on the air.

According to Air Force officials at the GPS Master Control Station, Schriever Air Force Base, Colorado, and Patrick AFB near the Cape Canaveral launch site, the questionable component is the 40-second timer that triggers separation of the third stage booster from the GPS space vehicle. Affected are both the 20th Block IIR-M, which had been scheduled to launch this month with a civil L5 test signal enabled in the navigation payload, and GPS IIR-21.

Applanix Launches POS AV with Integrated Trimble GNSS, Upgraded DSS RapidOrtho

Applanix has announced the availability of a high altitude tactical mapping option for its DSS RapidOrtho system as well as the integration of the Trimble BD960 GNSS receiver module for its POS AV airborne position and orientation system.

With the GNSS module, POS AV products now support GPS L1/L2 and GLONASS L1/L2 processing, both in real-time and post-mission. The BD960 will also be able to receive and process the next-generation GPS L2C and L5 signals.

GPS III Satellite Contract: An Undeclared Winner?

GPS III Satellite Contract: An Undeclared Winner?

GPS III conceptual drawing, The Aerospace Corporation

The Air Force has further delayed the announcement of its decision on who will be the prime contractor for the next block of GPS satellites, IIIA. Earlier reports had set the contract award announcement for early April.

On Wednesday (April 23), Anthony Russo, deputy director of the National Coordination Office for Space-Based Positioning, Navigation, and Timing (PNT), told a European Navigation Conference 2008 in Toulouse, France, that "source selection" has been identified. He added, "I had hoped to announce [the results] at this conference, but the process is not complete yet."

Source selection means that the GPS Wing at the Space and Missile Systems Center (SMC) has completed its
evaluation of the bids on the contract and the preferred provider for the new generation of satellites. The Wing — responsible for overseeing the acquisition of GPS space, ground, and military user equipment — has a presentation ready on the IIIA contract award but is waiting to brief the Air Force decision maker, in this case, apparently Air Force Secretary Michael Wynne.

Satellite Launch Will Aid DoD GNSS Users to Anticipate Space Weather Effects

Communication/Navigation Outage Forecasting System (C/NOFS) satellite, General Dynamics

On Wednesday (April 16), a U.S. Air Force team successfully launched the Communication/Navigation Outage Forecasting System (C/NOFS), an experimental satellite designed to monitor the ionosphere and predict conditions that would disturb radio communications, including GNSS signals.

The satellite was ultimately deployed from a Pegasus rocket following an air launch from a Lockheed L-1011 that had taken off from Kwajalein Atoll in the mid-Pacific Ocean. First transmissions from the spacecraft were acquired shortly after it reached orbit.
