Modernized Navstar Security Algorithm (MNSA) M-code Testing
SimMNSA
The M-code signal is part of the security architecture that all new Military GPS User Equipment (MGUE) has been required to use since 2017. Until recently, testing with non-classified AES-encryption and replay of M-code Satellite Data Sets (SDS) have been the only methods authorized for GPS M-code receiver testing using a constellation simulator.

GNSS Signal Generation System
GSS6300
The Spirent GSS6300 has been specifically designed to facilitate high-volume production testing for GNSS-enabled applications. Capable of generating a single channel of multiple GNSS in the L1 band individually or concurrently, the GSS6300 offers the fidelity and reliability needed for final functional testing of high-value critical systems.

Authorized GPS AES M-Code Testing
SimMCODE
Validate M-Code functions via AES M-code protocols for high fidelity secure testing. 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).

Inertial And Integrated GPS/Inertial (IGI) Sensor Testing
SimINERTIAL
Overcoming PNT/GNSS positioning challenges with precision inertial sensor emulation, for powerful IGI testing. Integrating inertial sensors is an effective way to overcome the weaknesses of GNSS positioning systems. However, it also adds a set of challenges to the development process. Once inertial sensors have been verified, it is necessary to test the complementary positioning systems alongside each other.

Testing M-code Using Simulator Data Sets
SDS M-code
Simulator Data Sets (SDS) contain official, pre-encrypted M-Code signal data streams. Comprehensive development and testing of military M-Code receiver technology in an unclassified laboratory environment have been possible by employing AES encryption. Spirent Federal has supplied AES M-code test capability since 2004 via the SimMCODE product.

Advanced GNSS Spoofing Simulation And Monitoring
SimSAFE
SimSAFE enables better protection against GNSS spoofing attacks. GNSS spoofing is a growing concern for developers and users of critical systems, with many well-publicized instances occurring every year. In order for users to be assured that their equipment continues to perform as expected when exposed to fake or replayed GNSS signals, it is vital to test thoroughly.
