Workshop 2017 - Richard Langley - As one of eight instruments of the Enhanced Polar Outflow Probe (e-POP) payload on the Canadian CAScade, Smallsat and IOnospheric Polar Explorer (CASSIOPE) small satellite, the GPS Attitude, Positioning, and Profiling experiment (GAP) can employ one or more of the four GAP-A dual-frequency GPS receivers and associated zenith-facing antennas to provide high-resolution spatial positioning information, flight path velocity determination, and real-time, high-stability timing. An improved precise-point-positioning processing engine will be used to produce high-accuracy time series of precise acceleration determinations, which can subsequently be used to infer density variations in the thermosphere.
