GPX 2 [NASA Langley]

NASA Langley Research Center's GPX 2 3U CubeSat is Technology demonstration mission that will provide a novel test-bed for Commercial Off-the-Shelf (COTS) differential global positioning systems (dGPS) that will enable future on-orbit assembly, docking, and formation-flying small satellite missions.

While on-orbit, it will assess the capability of unmodified, multi-frequency COTS dGPS receivers. One receiver will operate as a base reference as well as assess absolute position accuracy from an on-orbit COTS receiver. GPX2 is passively stabilized using a 2-meter gravity gradient boom, providing a local orbit horizon view to the GPX2 antennae and Iridium communication. By demonstrating dGPS on-orbit, GPX2 paves the way for on-orbit assemblyand autonomous robotic operationsusing high-accuracy dGPS to measure relative proximity and orientation.

It was selected in 2020 by NASA's CubeSat Launch Initiative (CSLI) to be launched as part of the ELaNa program.
