Digital Nav Payload Emerges as Factor in GPS III Re-Bid

Digital Nav Payload Emerges as Factor in GPS III Re-Bid

The advantages of a digital navigation payload, a technology singled out by both the House and Senate for $20 million worth of research support, appears to be a key factor in the Air Force’s search for a new GPS III contractor.

The digital payload “is a direct complement to the Production Readiness Alternate Sources Sought released in June,” Air Force officials said in an emailed response to questions about the technology and how it fits into the ongoing search for new GPS III suppliers.

As Galileo FOCs Near Launch, EC Holds Public Consultation on Open Service ICD

Installation of Galileo FOC satellite “Doresa” on the payload dispenser system. The first of two Galileo navigation satellites has been integrated on its payload dispenser system at Europe’s Spaceport in Kourou, French Guiana. The second satellite “Milena” was then installed in a side-by-side arrangement and will be mated atop a Soyuz Fregat upper stage. ESA/CNES/Arianespace/Optique Vidéo du CSG photo by P. Baudon

The European Commission (EC) has opened a public consultation on a newly revised version of the Galileo Open Service Signal in Space Interface Control Document (OS SIS ICD).
 
The consultation will take place through September 22, overlapping the scheduled first launch of fully operational capability (FOC) Galileo satellites on August 21. Details of the consultation process can be found on the EC Directorate-General for Enterprise website.

Portland, Oregon USA
√ Adidas has designed every official World Cup ball since 1970. And that’s not all! The Adidas Innovation Team in Portland, Oregon, spent 4 years on a smart soccer ball with a “six-axis MEMS accelerometer sensor package” that can detect speed, spin, strike and flight path data and whip it on over to the special GPS app on your iPhone. The app interprets the data for you, coaches you, and keeps a video to show your friends. On sale now for only $299.

New Leaders at the GPS Helm

New Leaders at the GPS Helm

Washington, D.C., has a peculiarity of seasons. While most of the world marks the shifts between winter and spring, summer and autumn, the politicos on the streets of the U.S. capital count the passage of time in two-year increments.

New operatives and appointees flock to the centers of power in the early days of each administration and the opening of each Congress, then migrate to friendlier climes as congressional elections loom and the administration winds down — as it is now.

GPS OCX Program Being Restructured as Budget Pressures Mount

In response to the ongoing federal budget squeeze, the U.S. Air Force is restructuring the contract for developing its new GPS ground system, a move that could further delay its completion.

The Air Force has asked Raytheon, its contractor for the Next-Generation Operational Control System (OCX), to develop an alternative plan in light of fiscal limitations.

“The current baseline approach is unaffordable” given the funding constraints and “appears to be a much higher risk,” said Steve Moran, the director of GPS Mission Solutions at Raytheon.

GPS IRT Shuffled, Shrunk in Budget Squeeze

Maj. Gen. (ret.) Robert A. Rosenberg, former GPS IRT chair

The GPS Independent Review Team (IRT), a key player in GPS policy for nearly 20 years, has been disbanded by the Air Force in what several sources say is an effort to save money.

Created in 1997 for a temporary three-month assignment, the IRT has been instrumental in shaping the current GPS constellation including designing military’s M-code — giving the signal its distinctive two humps — and pushing to get that signal into the constellation earlier than initially planned.

U.S. Air Force Authorizes Lockheed to Finish GPS III SVs 7 & 8

The U.S. Air Force has awarded Lockheed Martin more than $245 million in contract options to complete production of its seventh and eighth GPS Block III satellites.

The two space vehicles (SVs 07–08) received initial funding under a February 2013 long-lead material contract for the Air Force’s second set of four satellites, GPS III SV 05–08. Similar to this current award announced yesterday (April 1, 2014), the Air Force exercised an option to complete production of SVs 05–06 in December 2013.
