US military chooses Spirent for anechoic chamber testing

Spirent Federal Systems has been awarded a contract to support anechoic chamber testing for a major U.S. military agency.

Spirent’s GSS9790 multi-output, multi-GNSS RF constellation wave-front simulator will be used as the signal generator attached to multiple transmission antennas for broadcast into the chambers.

Within this design, the antennas are structurally distributed to represent the correct arrival vectors of the simulated satellite signals on the device under test, creating the most realistic test environment possible. In addition, the GSS9790 supports interference sources located anywhere in the chamber to imitate different threat scenarios.

“Interference can threaten GNSS signals in multiple ways,” explained Jeff Martin, VP Sales. “We recognize the need for controlled, repeatable conditions to combat these threats. The GSS9790 delivers all the tools needed to successfully mitigate them.”

The Spirent GSS9790 supports classified Y-code, SAASM and M-code and can be found in key government labs across the country.

The Spirent GSS9790 enables verification of CRPA systems, spatial testing of single-antenna devices, and real-world-time-synchronized indoor GNSS implementations. The system is a development of the Spirent GSS9000. Combined with Spirent’s SimGEN software, it offers a powerful test platform for anti-jam and interference testing.
