Global Navigation Satellite System Simulator

The USCG Academy has a need for a Global Navigation Satellite System (GNSS) simulator to support the mission and the education of next generation of USCG Officers. The USCG requires the technology employ Software Defined Radio (SDR) methods to maximize the flexibility of simulation capability. The simulator must be capable of simulating modern jam/spoofing threats, and must be capable of live-sky synchronization. 2. Size, Weight, and Power (SWAP) Specifications a.
