CLAW GPS Simulator (from Jackson Labs)

The CLAW 18-Channel Full-Constellation GPS Simulator is the industry's first fully-self contained, low size-, weight-, and power (SWaP) miniature GPS Simulator module. In comparison to competitive products that require external computers for processing and control, the CLAW Simulator works fully self-contained by storing location/time/date data in internal NV memory, or by storing complex vector data to simulate highly dynamic scenarios. The CLAW can also be used to transcode NMEA or SCPI position/velocity/time (PVT) data into GPS RF signals, therefore allowing retrofitting of legacy GPS equipment with the latest generation GNSS receivers such as Glonass, Galileo, BeiDou, SAASM, M-code, or even with INS capability.
