In order to facilitate greater accuracy and robustness than available in civilian GNSS, the US government has long provided secure signals for authorized users. M-Code is the latest iteration of this process, providing an encrypted and standalone service (unlike the P(Y)-Code). Spirent’s SimMCODE enables authorized users to thoroughly test Military GPS User Equipment (MGUE) in repeatable, lab-based environments, using the commercial encryption algorithm, Advanced Encryption Standard (AES).
Spirent was the first provider to be approved by the GPS Directorate to provide AES M-Code testing, and continues to lead the way in the implementation of new signals and technologies, such as the development and security approval of Spirent’s latest M-Code solution, SimMNSA, using the Modernized Navstar Security Architecture. SimMNSA is not limited in terms of location, date, time, and other critical testing variables. Generating real M-Code on the fly, with no need to use prerecorded data sets, SimMNSA greatly accelerates the receiver evaluation process.
