2. Integrated Communication Link and Global Positioning System (GPS) for Enhanced, Robust Position Information
The objective of the GPS Network-Assisted Positioning (GPS-NAP) program was to develop and demonstrate the ability to augment a GPS-derived navigation solution with “Network-Assistance” through a communication link to enhance the precision and robustness of the positioning information.  For this effort, NAVSYS developed a functional prototype GPS-NAP software application that could be easily transitioned into the next-generation Joint Tactical Radio System (JTRS).  These integrated designs can provide improved navigation accuracies in a GPS jammed environment and a significant performance improvement over previous Link-16 Relative Navigation (RELNAV) solutions.

3. Mine Counter Measures Precision GPS Ephemeris
In this program, NAVSYS worked with the Office of Naval Research (ONR) to improve the positioning and maneuvering accuracy of Mine Counter-Measure (MCM) platforms operating in the littorals in support of amphibious operations by Marine Corps Forces. NAVSYS completed end-to-end static and mobile testing at Dahlgren of the PGE Client operating on the Blue Force Tracking system to provide precision GPS navigation integrated with a DAGR.

4. Miniature, Low Power GPS/Inertial-Wireless Orientation Sensor.
In this project, NAVSYS prototyped an innovative approach to providing orientation information of weapons used in training. The Naval Air Warfare Center Training Systems Division (NAWCTSD) needed a solution to support training operations in both outdoor and indoor environments with precise 3-D positioning and weapon orientation to allow geometric pairing. NAWCTSD needed research solutions to provide a cost effective approach for dealing with this difficult problem. The project required the design, and prototype of electronic hardware including wireless communications, integration of inertial sensors into an inertial measurement unit (IMU), development of GPS RF front end and digitization hardware, development of small microprocessor based processing system which included SDR GPS processing and GPS/Inertial Kalman Filter algorithms.

5. Low Cost, Lightweight, Low Power Precise Positioning System (PPS) GPS Solution for Software Defined Radios
The Navy desires to incorporate GPS Precise Positioning Service (PPS) in small form factor Software Defined Radios (SDR). A GPS Selective Availability Anti-Spoof Module (SAASM) receiver is mandated by DoD to provide PPS, which entails direct P(Y) code acquisition. However, adding GPS SAASM receivers to radios with currently available hardware would increase their size, weight, and power.  The NAVSYS GPS-Lite API – an embeddable GPS software application – is being developed for SDR radios to allow embedding of a GPS PPS solution, as opposed to a dedicated hardware solution that would increase the size, weight, and power of the radios. Test results of the GPS-Lite performance under nominal and degraded GPS conditions exceeded the standard SAASM performance specification.

 6. GPS Jammer Locator
The NAVSYS Jammer Detection and Location (JLOC) System is a multi-year development and support contract to provide situational awareness of GPS interference events and effects to U.S. warfighters and planners worldwide.  To develop this system, NAVSYS worked with Air Force and National Agencies to collect and stream GPS interference data into a single database that can be used by approved subscribers over a secure network. Since its initial development, NAVSYS has continued to support the JLOC system with software upgrades, documentation and training support and follow-on enhancement efforts.

7. NAMATH
The NAMATH system was developed with the Air Force to provide greater GPS precision to critical operations such as target location generation, precision guidance of munitions, and precision georeferencing of sensors.  By increasing the accuracy of the GPS services, the following benefits are realized; (1) sub-meter positioning accuracy for precision target geolocation, (2) increased precision for GPS-guided munitions reducing the number of sorties required and increasing the probability of kill, and (3) increased integrity of the GPS services minimizing the probability for collateral damage.  NAVSYS continues to support and maintain this system under contract to the Air Force’s Air Combat Command.
