Global Positioning System (GPS) Modernization

Abstract

GPS Modernization delivers increased GPS AJ protection through modernized GPS receivers that will utilize the new Military Code (M-Code) GPS Signal in Space, incorporate enhanced cryptology, enable blue force GPS electronic attack, deliver greater position and time accuracy, and provide improved protection against signal spoofing as compared to legacy receivers. This effort supports Navy's compliance with Public Law 111-383, which requires that all GPS user equipment be capable of receiving the new GPS M-Code signal after FY 2017. To meet the Navy's fielding timeline, system engineering and requirement development efforts must begin before actual delivery of Military GPS User Equipment (MGUE). The integration timeline of modernized GPS receivers is 5+ years from planning to test and is dependent on platform. Each type/model/series aircraft uses a unique GPS receiver and GPS system configuration, which requires separate parallel platform integration and testing efforts to include: software updates to avionics and mission computers; modifications to the airframe based on Size, Weight, Power and Cost (SWaP-C) requirements; coordination with each Program Management Air (PMA) organization; management, oversight and support of each effort; and contracting and working with each platform integrator for the respective platform. Project currently consists of eleven (11) parallel efforts that integrate five (5) different Military Code (M-Code) Global Positioning System (GPS) receivers into different type model series aircraft. The M-Code receivers are being developed under two (2) Air Force programs, Miniaturized Airborne GPS Receiver 2000-Modernization (MAGR2K-M) and Embedded GPS/Inertial Navigation System (EGI-M). The EGI-M program includes the LN-351, LN-300, Accurate Navigation System - Modernization (ANAV-M) and H-764-M. CMV-22B/MV-22B and E-6B will integrate the MAGR2K-M. F/A-18E/F and EA-18G will integrate the ANAV-M. E-2D, CH-53K, P-8A, MQ-4C, and MQ-8C will integrate the LN-351. MH-60 R/S will integrate the LN-300. Additionally, project will integrate Military Code (M-Code) receivers into existing Embedded Global Positioning System/Inertial Navigation System (GPS/INS) (EGI) to support the following aviation platforms: F/A-18 E/F, EA-18G, E-2D, P-8A, CH-53K, MH-60R/S, AH-1Z and UH-1Y, due to delays in development of M-Code capable Embedded GPS/INS (EGI-M).
