Keysight PNTF211A SimMNSA GPS Military Code Simulation Software
Capabilities
- Implements MNSA - the next step beyond Advanced Encryption Standard (AES) and Simulator Data Sets (SDS) methods for GPS M-Code simulation
- Complete user control over scenario configuration, including signal conditions and threat environments
- Simulate Regional Military Protection (RMP)
- Support for Blue Force Electronic Attack scenarios, enabling continued M-Code operation while denying commercial GPS signals
- High-fidelity, mission-ready testing compliant with M-Code specification
- Available to authorized users of the PNT X simulation system
- Granted security approval by the Global Positioning Systems Directorate
Integration
- PNT X - Assured PNT and NAVWAR simulation system
- PNT X Controlled Reception Pattern Antenna (CRPA) Test System - anti-jam antenna wavefront test system
SimMNSA enables authorized U.S. users to test MGUE M-Code receivers with real M-Code signals in secure, lab-based environments for assured PNT performance.
SimMNSA delivers Modernized Navstar Security Architecture (MNSA) M-Code simulation as a software upgrade for the PNT X simulation platform. It is a scalable, flexible solution that accelerates development timelines, enables confidence in M-Code performance, and strengthens warfighter readiness.
