SOCRATES

The SOCRATES (Signal of Opportunity Cubesat Ranging and Timing Experiments) is a 3U CubeSat mission by the University of Minnesota for a technology demonstration mission to advance the Technology Readiness Level (TRL) of a new timing and navigation sensor for CubeSats from TRL 5 to 7.

The Gamma Ray Incidence Detector (GRID) sensor being developed is a gamma-ray (and hard x-ray) detector optimized for making accurate positioning, navigation and timing (PNT) measurements. In operation, it will use signals of opportunity (e.g., naturally occurring gamma-ray emissions for sources such as Gamma-Ray Bursts or GRBs) as navigation and timing beacons akin to GPS satellites.

It was selected in 2017 by NASA to be launched as part of the ELaNa program.
