Synopsis
Air carrier flight crew reported they encountered GPS jamming in cruise flight in the vicinity of ABQ.
Narrative
Aircraft X; FL 340; approaching ABQ with reported electromagnetic interference in the area by ATC and other aircraft. Aircrew noticed the Advanced Gauge Display (AGD) was displaying ADS-B Inop. Subsequently; the aircrew received the NAV FM/GPS POS DISAGREE ECAM caution. After running the appropriate ECAM action; the Captain (pilot monitoring (PM) referenced the QRH and ran the NAV FM/GPS POS DISAGREE checklist. Estimated accuracy was below required accuracy; and FM position agreed with onside Global Positioning/Inertial Reference System (GPIRS) position. First Officer (pilot flying (PF) navigated through several areas of convective activity with heading mode; while verifying aircraft's position with ground NAVAIDS. NAV FM/GPS POS DISAGREE ECAM resolved itself west of ABQ; aircrew confirmed aircraft position via ground NAVAIDS; estimated accuracy and FM/GPS comparison and then proceeded directly to BLD [VOR] via NAV mode; then to ZZZ via flight planned route without further incident. While preparing for the visual approach XXR into ZZZ; aircrew determined that GPS 2 Position display was blank. Weather at ZZZ was VMC and aircrew flew the visual approach and landed in ZZZ without further incident. Aircrew requesting further information regarding electromagnetic interference and resulting GPS failure; if available.Cause: Electromagnetic Interference.
Second reporter narrative
During cruise at FL320 and while deviating around some thunderstorms; aircraft exhibited NAV FM GPS Pos Disagree ECAM message. I was pilot flying (PF) and continued flying while Captain ran QRH checklist. We verified ANP was better than RNP and Global Positioning/Inertial Reference System (GPIRS) solution was usable. ADS-B in fail message and ATC fail light were on during period where both GPS were unreliable. Continued flight using FMS position solutions and ground based navaids. GPS1 restored itself about an hour later and flight landed in ZZZ uneventfully. Wrote up GPS2 which was blanked out.Cause: Flight through EMI.Suggestions: Don't plan flights near missile ranges and other locations employing GPS jamming.
