An OPSGROUP member reported a new GPS spoofing encounter<\/strong> yesterday in the Ankara FIR, while flying southbound between UDVET and INPOR.<\/p>\n

The encounter began around 1200Z, when both selected GPS positions began to show the aircraft position as being over OLBA<\/strong>\/Beirut – approx 120nm away<\/strong>.<\/p>\n

\"\"<\/a><\/p>\n

The crew had disabled GPS inputs prior to the area, but briefly selected them again on the PNF side – when the spoofing began. The route flown during the event was essentially a straight line from LTAF\/Adana to LCLK\/Larnaca.<\/p>\n

The aircraft was a Global Express 7500 at FL470. OLBA\/Beirut is in one of the three hotspot areas<\/a> for GPS spoofing, but this one over Adana is perhaps the furthest away yet to report the problem.<\/p>\n

Analysis<\/strong><\/h4>\n

This is a great example of how GPS spoofing works. The Nav Display shows the fake GPS position<\/strong> with the star symbol – located exactly at OLBA\/Beirut airport.<\/p>\n

The aircraft position<\/strong> however – thanks to the crew disabling GPS sensors – is correctly shown over LCLK\/Larnaca.<\/p>\n

If the crew had not proactively disabled those sensors, the aircraft position would also be shown as over OLBA – and if the spoofing was subtle, the FMS would tend to start suggesting a right turn back to the track inbound ODELO.<\/p>\n
