Collins GPS Receivers Suffer Reception Outage

 - June 10, 2019, 12:33 PM

According to a notice from NBAA Traffic Services sent yesterday, “Numerous calls and emails have come in to the desk this morning in reference to GPS signal disruption.” The disruption appears to affect only certain Collins Aerospace (formerly Rockwell Collins) GPS receivers, and Collins Aerospace confirmed to AIN, “We identified a technical issue with our recently released GPS product(s) impacting availability, and have since determined the root cause and the resolution. We are engaging with our customers to ensure continued safe operational capability.”

According to Collins Aerospace, the affected GPS receivers are GPS-4000S part number 822-2189-100 and GLU-2100 part number 822-2532-100. 

The NBAA notice pointed out that the FAA had issued a blanket exemption to allow the affected aircraft to be flown below FL280 and if unable to fly RNAV routes, to use “traditional airways and/or navaids.” The exemption, however, was valid only through today at 0400 UTC.

According to OpsGroup, members have reported that affected aircraft include the following: Bombardier CRJs and Challenger 300/350, Boeing 737-900, Hawker 750 and 850XP, Cessna Citation CJ3, Gulfstream G200 and G280, Airbus A320, and Boeing MD11.
