Captain reported GPS jamming in OPLR airspace at FL320 resulting in false GPWS indications and warnings.
Pilot narrative
Verbatim, de-identified by NASA. Placeholders: ZZZ,
X, Y.
At FL320 at 40NM south of INDEK on airway L509 we experienced GPS jamming. As a result the GPWS first gave us a “terrain, terrain, terrain” warning followed by “pull up, pull up, pull up”. We began noticing the GPS jamming once entering Lahore airspace so the GPWS warning was not a surprise as we knew our position along the route.
