Global Navigation Satellite Systems Engineering, Policy, and Design
An executive summary of a special report by RTCA Inc. Special Committee 159 released today (May 27, 2011) indicates that GPS aviation receivers would experience serious interference from transmission planned by LightSquared in the upper portion of the 1525–1559 MHz spectrum adjacent to the GPS L1 band.

The National Space-Based Positioning, Navigation, and Timing (PNT) Advisory Board will meet in Arlington, Virginia, on Thursday, June 9 and Friday June 10. The sessions are open to the public.
Among the agenda items are GPS modernization, interoperability with other GNSS systems, and future challenges to PNT service providers and users, such as protecting the emerging role of PNT in cyber networks, including the need for backups.

Septentrio has announced plans to release the AsteRx-m, a low-power GPS/GLONASS dual-frequency RTK receiver that is smaller than a credit card.
The new board, which will begin shipping in the third quarter of 2011, is aimed specifically at integration in handheld devices, mobile computing platforms, and other solutions requiring high accuracy combined with low power in applications where space is at a premium. The new receiver covers the functionality range from GPS-L1 only to full GPS-GLONASS L1-L2

After a long series of fits and starts, the Department of Homeland Security is tackling the issue of interference to the GPS signal. The agency has launched a study to assess the risks to GPS service from a variety of sources — a study that, at least on paper, will lead to a plan to mitigate interference.
Unfortunately, the effort will not directly address the one potential problem consuming the thoughts of the GPS community — widespread receiver overload from the high-powered mobile broadband service proposed by the Virginia firm LightSquared.

Uninterrupted continuous positioning technology is no longer a "nice to have" option but, for many applications, a "must have" requirement. Mobile devices increasingly rely on position/location functionality, and users have little tolerance for gaps in service.

NASA’s May 3 announcement that its long-running Gravity Probe B (GP-B) mission had confirmed two key predictions derived from Albert Einstein’s general theory of relativity, mentioned GPS autoland techniques as one of the projects spinoffs.
However, the involvement of GPS technology and GPS experts in the mission was much deeper than the passing reference in a press release.
But first, the news.
