M-Code Type II

The Type II standard offer hosts the same M2GRAM and MGUE capability as the GB-GRAM Type I. The Type II offers the warfighter backwards compatibility to the Y-code signal as well as the advantage to use the modernized M-code signal. Tracking either signal delivers assured precise positioning and timing with protection against GPS jamming and spoofing for successful military operation. TruTrak-M Type II is integrated on ground, undersea, low-dynamic airborne and launch / low earth orbit platforms.

Key Features

  • Tracking C/A, Y-, and M-code signals on L1 and L2 frequencies
  • Backwards compatibility to Type I/II SAASM-based GPS
  • Small (1/2 Type I) form factor size with same connector
  • Direct Y-code and M-code acquisition
  • Unclassified when keyed
  • Anti-jamming and anti-spoofing for assured solutions in adversary threat environments
  • Hot start for either Y-code or M-code
  • Field re-programmable
  • Security certified and approved
