White House Moves to Harden Infrastructure against GPS Disruption

System engineers across the country may soon be planning, in some cases perhaps for the first time, what they would do if they could not use the GPS service.

The effort is part of an expanded White House initiative to protect the nation’s critical infrastructure. Alhough infrastructure protection programs have been under way for some time, they did not necessarily address GPS vulnerabilities explicitly.

MUSTER

Existing methods for improving the GNSS performance commonly attempt to enhance the signal processing and navigation estimation parts of a single receiver. Such approaches, however, leave unexplored the potential benefits inherent to the integration of data from multiple receivers.

Paul Flament is head of the European Commission’s Satellite Navigation Unit. His primary job, essentially, is to manage the Galileo program of the European Union (EU). With four operational satellites now in orbit and an ambitious schedule to set in place a constellation of 26 by 2015, Flament sat down with Inside GNSS to talk about a number of pressing issues that could affect the future of Galileo.

Flament first addressed the EU GNSS Regulation, the much-anticipated document that sets out just who will do what in the future Galileo program.

The Air Force will decide this fall whether to build more GPS III satellites or move to a new generation of spacecraft, the leader of Air Force Space Command told Congress last week.

“We’re on contract right now . . . through (GPS III) satellite vehicle number eight. Satellite vehicles nine and beyond – the acquisition strategy for that – will be debated in the fall,” General William Shelton, commander of Air Force Space Command (AFSPC), told the House Armed Services Committee on April 25.

Topcon Launches OEM Precise Heading Product

Topcon Positioning Systems (TPS) has announced the MR-1 Heading System, an OEM GNSS solution for high-performance positioning and heading applications on moving platforms.

Using the MR-1 receiver and Topcon’s patented MG-A8 antenna, the system provides “centimeter-accurate RTK positioning and better than 1/10 of a degree heading accuracy in challenging environments,” said Doug Langen, TPS GNSS product manager.

Military GPS Budget Appears Steady as President Bids to Slow Defense Cuts

Spending pressures on the Pentagon seem to be coming from every direction, and the GPS program appears unlikely to avoid them entirely.

The growing needs of veterans are poised to force up health care budgets and higher transportation costs and operating tempos have dug a $22 billion-hole in the accounts for Overseas Contingency Operations in places such as Afghanistan.

NovAtel Launches New Series of SPAN IMUs

NovAtel Inc. has announced its new SPAN-IGM series of micro-electromechanical system (MEMS) inertial sensor products, including the IMU-IGM-A1 MEMS enclosure and the SPAN-IGM-A1 GNSS/INS enclosure.

The IMU-IGM-A1 is a small , rugged enclosure that houses a MEMS inertial sensor, which can be configured from the factory as an integrated GNSS + Inertial Navigation System (INS) or as a standalone IMU sensor for pairing with a customer’s existing SPAN-enabled OEM6 receiver. Its dimensions are 152 (length) x137 (width/diameter) X 51 (height) millimeters.
