Spirent Federal Systems, provider of GPS/GNSS test equipment, has announced that its new M-code solution, SimMNSA, has been granted security approval by the Global Positioning System Directorate.

In 2017, Spirent Federal Systems partnered with Rockwell Collins to develop new software that will use the Modernized Navstar Security Algorithm (MNSA). This new approach of M-code simulation adds to Spirent Federal’s portfolio of classified signal simulation solutions, and will be available to authorized users of the GSS9000 series simulators.

“With the increased focus on M-code by the GPS Directorate, we are pleased that our team has paved the way in the development of SimMNSA,” said Ellen Hall, CEO of Spirent Federal Systems. “It was a great challenge to get to this point, but we are excited about what we have accomplished.”

The new test solution continues Spirent Federal Systems history of innovation and being first to market with M-code simulation software, the company said. Spirent’s GPS/GNSS solutions have supported numerous government, military and U.S. Department of Defense programs for more than 30 years.
