Highlights

SimMCODE provides authorized users with lab-based testing of Military GPS User Equipment (MGUE) using commercial Advanced Encryption Standard (AES) M-Code encryption.

  • Validates GPS M-Code functions via AES M-Code protocols for high-fidelity secure testing
  • Provides an encrypted, standalone service — unlike P(Y)-Code
  • Enables testing in repeatable, lab-based, non-classified environments
  • First solution approved by the GPS Directorate for AES M-Code testing
  • Supports M-Noise — spectrally equivalent M-Code modulation to test effects on tracking and acquisition for legacy L1/L2 signals and L2C
  • Uses commercial encryption algorithm for authorized M-Code function testing

Capabilities

  • M-Noise — spectrally equivalent M-Code modulation to test its effects on tracking and acquisition for legacy L1/L2 signals and the new L2C
  • AES M-Code — enables authorized users to test M-Code functions using commercial encryption algorithm

Integration

  • PNT X — Assured PNT and NAVWAR simulation system
  • PNT X Controlled Reception Pattern Antenna (CRPA) Test System — anti-jam antenna wavefront test system
  • PNT Xe — GNSS simulator for targeted development and validation testing
