Interference Simulation System

The GSS7765 Interference Simulation System (ISS) is a solution that fully integrates commercial-off-the-shelf(COTS) signal generators as interference sources with Spirent SimGEN-based satellite navigation simulators, suchas the PNT X, GSS9000 and GSS7000. Figure 1 shows a typical solution with the GSS9000 . The ISS is designed for testing interference immunity of GNSS devices in a simulated environment.Currently, up to 4 interference signal generators may be controlled via Ethernet from the simulator’s SimGEN hostcontroller. The interference signal is defined, along with all the other scenario parameters, from within the SimGENfor Windows GUI environment.The GSS7765 supports CW, swept CW, stepped CW, pulsed CW, AM.
