Navy Seeks Spoofing Solution from Rockwell Collins

The Office of Naval Research has awarded Rockwell Collins a contract to develop technology to locate and classify an adversary’s attempts to interfere with GPS signals and disrupt military operations.

“This program will help assure that essential high accuracy navigation and timekeeping services are available to weapons platforms and military users while enabling warfighters to identify potential threats,” said John Borghese, vice-president of the Rockwell Collins Advanced Technology Center.

A September report on unmanned aircraft systems (UAS) by the U.S. Government Accountability Office (GAO) highlighted the potential risks posed by GPS jamming and spoofing but failed to make any new recommendations on how the issue should be addressed. Associated privacy issues, however, have gotten more attention.

GNSS Augmentations

Dr. Todd Walter, Stanford University

Contrary to a widely held public impression, the elimination of GPS Selective Availability in 2000 did not take care of the needs that many users have for enhanced GNSS capabilities.

Indeed, various “augmentations” have been developed to meet the requirements of some applications for better accuracy, availability, or integrity (the assurance of the quality of a signal) than are available from GNSS signals in space.

[Updated October 26, 2012] A Soyuz ST-B launcher carrying two Galileo in-orbit validation (IOV) satellites took off as scheduled at 18:15 GMT (20:15 CEST; 2:15 p.m. EDT) on October 12 from the European Spaceport in French Guiana.

All the stages of the Soyuz vehicle performed as planned and the Fregat-MT upper stage released the Galileo satellites into their targeted orbit close to 23,200 kilometer altitude, three hours 45 minutes after liftoff.
