Experts: Exclusion Zones Around GPS-Interference Problematic; LightSquared/GPS Lawsuit Settlement Talks a No-Go

In the same week conflicting court filings underscored the intractability of the fight between LightSquared and GPS receiver manufacturers.

Meanwhile, a key technical group found that aviation likely would be hampered — yet not fully protected — by exclusion zones around wireless broadband transmission towers using, as LightSquared has proposed, frequencies adjacent to GPS bands.

Key Lawmakers Move to Make DoD Responsible for eLoran, GPS Backup

Key Lawmakers Move to Make DoD Responsible for eLoran, GPS Backup

A quintet of well-placed lawmakers, tired of federal dawdling, are prepared to make the Pentagon responsible for building and maintaining eLoran as a backup system for GPS. The move could come by the end of the year, possibly through language attached to a must-pass bill.

Leading the bi-partisan charge are Duncan Hunter, R-California, chairman of the House Transportation and Infrastructure Committee, and the subcommittee’s ranking member John Garamendi, D-California.

Officials Delay First GNSS Authorization Request; Light-Squared Tries to Leverage Issue

Officials Delay First GNSS Authorization Request; Light-Squared Tries to Leverage Issue

The U.S. stance on satellite navigation has long supported international cooperation and a degree of interoperability. In 2010 the Obama administration even adopted a space policy that said foreign satnav services could be used “to augment and strengthen the resiliency of GPS.”

That was easier in the abstract, however, when the only fully functional GNSS was GPS. Now, with other GNSS services coming online, American officials want to think things through again.

10th GPS IIF Satellite on Its Way to Orbit

The U.S. Air Force and its mission partners successfully launched the 10th Boeing-built GPS IIF satellite aboard a United Launch Alliance Atlas V from Cape Canaveral Air Force Stations today (July 15, 2015).

The spacecraft is destined for plane C/slot 3 of the GPS constellation

The launch almost coincided with Friday’s 20th anniversary of the declaration of full operational capability (FOC) for the GPS constellation, which occurred on July 17, 1995.

Just two GPS IIF satellites remain to be launched — Atlas V rockets will be used to launch both.

New PRS-Capable GNSS Receiver Platform from QinetiQ

New QinetiQ PRS-capable receiver

British manufacturer QinetiQ has today (July 14, 2015) announced its progress in developing a GNSS navigation receiver that can process encrypted Galileo Public Regulated Service (PRS) signals.
 
The multi‑constellation, multi‑frequency receiver is a significant step in the company’s GNSS technology development, says QinetiQ, which expects to bring to market by 2020 end-user products for navigation, tracking, and timing based on the new receiver design. That timeline parallel’s the Galileo program’s current schedule for completing its satellite constellation.
