09/20/2017 - Rockwell Collins working with Spirent Federal to develop M-Code (MNSA) capability

Pleasant Grove, UT, September 20, 2017-Spirent Federal Systems, the nation's leading provider of GPS/GNSS simulators, has announced today that they are working with Rockwell Collins to develop software that will support M-Code using the Modernized Navstar Security Algorithm (MNSA).

Spirent Federal announced earlier this year that they have received approval from the GPS directorate to begin development of software capable of supporting M-Code using the Modernized Navstar Security Algorithm (MNSA). Spirent is one of the first companies to receive approval from the GPS Directorate to begin developing this kind of software.

"We are excited to team with Rockwell Collins in developing our newest M-Code capability that can be added to the Spirent GSS9000 series simulator," said Ellen Hall, President of Spirent Federal Systems. "We have a rich history of working with Rockwell Collins, and they expressed interest in this important project. We know that this product will be a valuable asset to the M-Code community."

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 provided AES M-code and SDS M-code capable simulators for many years, and as the long awaited MNSA M-code signals become available, Spirent Federal Systems is planning to make this option available to authorized users on its GSS9000 series simulator.

Spirent Federal will be exhibiting at ION GNSS in Portland, Oregon on September 25-29. They are encouraging interested customers in stopping by Booth A for more information.
