Spirent Federal developing MNSA-capable simulators

Spirent Federal Systems, a provider of GPS and GNSS simulators, has begun developing MNSA-capable GNSS simulators for the Modernized Navstar Security Algorithm.

Spirent Federal is developing software that will support M-code using MNSA. M-code is an updated GPS military signal that is being rolled out as part of the modernization of the current GPS constellation.

GPS modernization began in 2000 when the GPS Selective Availability feature was set to zero. Since that time, the U.S. Air Force has been working on newer generation satellites that will transmit new civilian and military signals.

Until now, AES and SDS have been the only methods authorized to be used within a GNSS simulator to produce M-code.

Spirent Federal Systems has been a provider of AES M-code and SDS M-code capable simulators for many years, but as the long awaited MNSA M-code signals become available, Spirent Federal Systems will be making this option available to authorized users on the GSS9000 series simulator.
