DoT Seeks Help from Receiver Manufacturers to Decide on GPS SVN49 Mitigation

[Updated March 27] The first of two  teleconferences hosted by the GPS Wing underlined the U.S. Air Force’s desire to gain greater participation by manufacturers of user equipment in sorting out the options for mitigating the effects of a signal anomaly on the GPS satellite known as SVN49.

The March 26 teleconference, held on the same day as publication of a notice in the Federal Register inviting public comment on nine possible options for dealing with the anomaly, drew only a handful of participants. But the U.S. Department of Transportation Research and Innovative Technology Administration (RITA), which issued the invitation, and the GPS Wing, which has the lead in implementing an eventual decision, hope to see further industry participation in written comments and a second teleconference planned for April 30.

GPS Jamming and Interference Sparks UK Concerns, Technical Solutions

Prof. David Last at DSKTN symposium

The noise floor seems to be rising on the subject of GNSS vulnerability to  jamming and interference. Recently, the United Kingdom provided the locus for a trio of initiatives that reflect growing anxieties about the widespread global dependence of critical position, navigation, and timing (PNT) applications and infrastructures on the low-power signals from space.
