Global Navigation Satellite Systems Engineering, Policy, and Design
As I pack my bags for the damply enticing venue of Savannah, Georgia, I’m reminded that this is my 21st consecutive journey to an ION GNSS conference. And the number 21 still has a lingering resonance as the age of majority, the harbinger of having reached adulthood — if not maturity.

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.

Thalwil, Switzerland–based embedded GNSS receiver provider u-blox has announced the upgrade of its core CMOS technology to u-blox 6, with substantially reduced power requirements as the result of new "intelligent," user-selectable power management features. According to the company, these innovations enable significantly extended battery life for power-critical GPS applications.

When the GPS program was established, military services were undoubtedly targeted as its primary user group, focusing on outdoor operations and offering the capability of continuous tracking. In addition we have heard several times that GPS was planned as a dual-use system from its very beginning.

A GPS community consensus is emerging that the initial proposal for mitigating the L1 signal anomaly causing elevation-dependent ranging errors on the SVN49 satellite isn’t the best approach.

The recent GAO report and Government Oversight subcommittee hearing on GPS sustainability generated more heat than light, with some major news media outlets leaving the impression that the sky (or at least GPS satellites) would soon be falling.
Perhaps the only silver lining in the ensuing Chicken Little phenomenon was the crude measure it provided of just how familiar (but not necessarily knowledgeable) private citizens have become with GPS.

A $97.4-million reduction in the GPS program made by the U.S. House of Representatives would affect the modernization program for the operational control segment (OCX), not the GPS III satellite budget as reported earlier.
In adopting the action of its appropriations committee, the full House approved H.R. 3326, the Department of Defense (DoD) Fiscal Year 2010 (FY10) budget, on July 30. The bill was referred to the Senate Appropriations Committee on August 3. In its report on the bill, the House committee said it made the cuts because of contract delays in the OCX program.

The Indian Space Research Organization (ISRO) has awarded a new $82 million contract to Raytheon Company to modernize the Indian air navigation system.
Raytheon will build the ground stations for the GPS-Aided Geosynchronous Augmented Navigation System (GAGAN), and the Indian Space Research Organization will provide the space segment and additional ground equipment. GAGAN will provide satellite-based navigation for civil aviation over Indian airspace and adjoining areas in south and east Asia.
