The Global Positioning and Navigation Systems (GPNS) Integrated Product Team's (IPT's) laboratories evaluate and sustain existing and legacy capabilities to ensure warfigher preparedness and explore new concepts to meet the future needs of the navigation community using advanced capabilities and RDT&E tools. The laboratories provide a wide array of RDT&E services, such as inertial testing, software development, antenna testing, cryogenic research and sea and air integration.
PNT Systems Simulation and Test
The GPS Central Engineering Activity (CEA) Laboratory exercises GPS receiver hardware and software dynamically under precise and repeatable laboratory conditions through real-time simulation of both GPS satellite signals and host vehicle sensors and communications. The laboratory supports testing of all-in-view, attitude determination, differential and modernization (GPS M-code, L2C, L5) capabilities for IF, RF or digital waveform-based systems with a dynamic simulation accuracy of less than 2 centimeters. The GPS CEA Laboratory features a robust multiple-jammer simulation capability using advanced, computer-controlled signal generation equipment. The laboratory conducts the verification and validation of the function and performance of legacy receivers, as well as the latest GPS engines and their various form factors, such as GPS Receiver Application Module (GRAM) and Selective Availability Anti-Spoofing Module (SAASM) devices. The GPS CEA Laboratory provides interoperable links to related C4ISR laboratories and facilities to support warfighter preparedness.
Research and Development (R&D)
The IPT's R&D activities include the development of advanced algorithms and high-performance parallel computing models for improved GPS navigation performance and interference mitigation. The IPT conducts RDT&E of superconducting and cryogenic circuit technologies that enable high-performance high sensitivity and EMI-tolerant software-defined receivers. R&D activities also include testing unique receiver hardware, including superconducting microeletronic analog-to-digital converters and cryogenic filters.
Aircraft Navigation Systems Integration (ANSIL)
The Aircraft Navigation Systems Integration Laboratory serves as a system architecture development test bed for aircraft flight systems, displays and the Operational Flight Program (OFP) software. By using platform hardware and systems, simulation software and platform OFP, the ANSIL laboratory supports comprehensive system verification testing prior to installation on an operational platform.
The GPS Fleet Engineering Facility performs testing and check out of GPS receiver and ancillary equipment prior to installation. This facility is also used for life-cycle support of WRN-6, Navigation Sensor System Interface (NAVSSI) Lite and other GPS equipment returned from the fleet before reuse. The facility also tests and reprograms airborne GPS equipment prior to installation in aircraft.
