Spirent Federal Systems will demonstrate its GSS9790 simulator at ION GNSS+, taking place Sept. 14-17 in Tampa, Fla. The Spirent demonstration “Interference and Anti-jam Antenna Testing Using the Spirent Wavefront Simulator (GSS9790)” will take place in Room 17 on Thursday, Sept. 17, 2-2:45 p.m. Attendance gains one ticket for an Apple Watch raffle, with the winner to be announced Thursday at 4 p.m., Booth C in the Exhibit Hall. The ability of a CRPA to null out unwanted signals while still allowing wanted signals to be received is key to its performance. This ability allows GNSS receivers to continue to operate in challenging signal environments, Spirent said in an email. The similar but slightly different signal composition at each antenna element allows the CRPA to distinguish direction for wanted and unwanted signals. Recreating this signal environment in an anechoic chamber is critical in allowing the discerning test professional to rigorously evaluate the performance of a CRPA system. The Spirent GSS9790 is designed for this testing. The 9790 allows for code, carrier and amplitude control on a satellite-by-satellite and interferer-by-interferer basis.
