The Military GPS User Equipment (MGUE) program has spent the last seven years preparing M-Code receivers for fielding. This effort completed with the Technical Requirements Verification (TRV), Security Certification of the Common GPS Module (CGM), Security Approval of the Small Serial Interface (SSI) Type I receiver card, and JLTV PEO Certification of readiness for a Field Utility Evaluation (FUE). This technical baseline provides the building blocks for a family of M-Code GPS products from L3Harris.
The receiver hardware and software baselines are continuing to evolve to meet the needs of the Warfighter. The software is being updated through the government Request for Change (RFC) process merging new functionality into this proven baseline. The hardware has evolved into a smaller SSI Type II receiver through internal product development. This updated software runs seamlessly on both the SSI Type I & II platforms simplifying the Security Certification process.
The core building block of the GPS receiver, the CGM, has been adapted to meet the requirements of a host of new applications. The leading application of MGUE technology is coming from the PGK program. They are leveraging the Y-Code capability of the receiver for initial deployment and have their M-Code upgrade path completed simply by loading an M-Code key. The MGUE Y-Code receiver brings along all the advanced anti-spoofing (AS) capabilities of MGUE along with the resiliency improvements to ensure only know good inputs are being used in forming a Assured-PNT solution. All this with a simple path to M-Code.
Not to be out done by the projectile applications, the mounted and dismounted applications are using M-Code to address a variety of mission challenges. Integrated with multi-channel anti-jam (A/J) capability, the mounted applications enjoy the highest level of jamming immunity. This AJ capability integrated with on-board AS provides an Assured-PNT solution in the most contested environments. The handheld applications are adapting the configurable CGM to provide a low power solution for the dismounted users.
The services are integrating the M-Code receivers into lead platforms for test and evaluation, they include both the JLTV and Stryker. The results of this integration has produced positive results in preparation for launching M-Code into the field.
As with any completion, the hard work does not stop. The Next Generation ASIC (NGA) continues to build upon the current CGM and add more capability to support the Warfighter. This next generation GPS processing engine will use 14nm technology with adequate throughput and memory reserves to address future threats from nation states. The reduced SWaP-C will enable even the most power challenged dismounted users the ability for precision navigation.
M-Code… Here today to support our Warfighters and evolving into the future with next generation GPS.
