Rockwell Collins' Global Positioning System (GPS) expertise offers pinpoint accuracy for every airborne and surface mission worldwide. GPS is a satellite-based radio positioning system that provides 24-hour three-dimensional position, velocity and time information to suitably equipped users on or near the surface of the earth.

Airborne
For airborne users, Rockwell Collins' GPS Embedded Modules (GEM) and Airborne Selective Availability Anti-Spoofing Module (SAASM) Receivers (ASR) contain jam-resistant circuitry and are capable of withstanding 9g of shock. The Rockwell Collins GEM is a GPS Receiver Application Module (GRAM-S)-compliant receiver and the ASR provides the same functionality in a reduced form factor for space-constrained applications. 

Supporting Navigation Warfare (NAVWAR) and Communication, Navigation, Surveillance/Air Traffic Management (CNS/ATM) requirements, the Rockwell Collins GEM and ASR are available in 12- and 24-channel variants with all-in-view and dual frequency. Our latest GEM VI module provides an additional digital interface to support a 16-beam anti-jam system. Incorporating Rockwell Collins' proven techniques, the GEM VI includes numerous advanced features such as all-in-view satellite tracking for optimized geometry and satellite drop-out immunity. Operating as an embedded module or as a stand-alone receiver, the GEM VI flexible Input/Output (I/O) supports open system architectures.

Surface
For surface users, Rockwell Collins provides GPS capabilities that are available for use in any federal, civilian, Department of Defense or international platform. We supply today's soldiers with our Defense Advanced GPS Receiver (DAGR), which is a small and low-weight handheld receiver. It operates with an easy-to-use man-machine interface (Graphical User Interface and moving-maps) and a proven design that passes environmental, serial port and software testing for a low-risk, field-ready unit. DAGR incorporates anti-jam improvements for enhanced protection and is the first U.S. handheld GPS receiver program to include the next-generation security device, Selective Availability Anti-Spoofing Module (SAASM). Rockwell Collins has delivered more than 200,000 DAGRs to the warfighter.

Rockwell Collins is also providing a small, third-generation embeddable GPS receiver, called the Miniature Precision Lightweight GPS Receiver Engine SAASM (MPE-S). The MPE-S falls under the Ground-Based GPS Receiver Application Module (GB-GRAM) program, which is the U.S. Army's standard embedded GPS receiver. Rockwell Collins has delivered over 40,000 GB-GRAM units that are used on more than 50 platforms, including handheld computers, Unmanned Aerial Systems (UAS), robotic ground systems and underwater vehicles.

For the commercial market, Rockwell Collins offers the Polaris Guide GPS handheld receiver and Polaris Link, an embeddable card. The Polaris Guide offers the same functionality and ruggedness as the DAGR, while incorporating Rockwell Collins' 12-channel all-in-view Standard Positioning Service (SPS) Course Acquisition (C/A) code module, as well as the NightHawk 12-channel GPS signal processor. The Polaris SPS family of products  is available for use to both non-military and military customers, as well as NATO and non-NATO countries requiring SPS real-time GPS data.
