Troubleshoot Before Takeoff Modeling and Simulation for Navigation System Testing Sep 1, 2006 By: Curtis Hay, Colin Ford, Greg Gerten

Modeling and simulation, two separate but related activities conducted prior to flight tests of high-performance military navigation systems, can reduce costs, shorten timelines, and remove some uncontrollable variables from the process, to deliver more accurate, verifiable results.

Aerial Advantage: Robust Sensor Fusion for GPS Inertial Measurement Units in Diverse Flight Environments A solid-state GPS navigation system enables widespread use of GPS in smaller manned and unmanned aircraft, achieving the accuracy and robustness typically associated with larger, higher cost systems. The NAV420's sensors, data-acquisition elements, and Kalman-filter-based algorithm allow smaller aircraft to be deployed more easily for a variety of missions — at less than one-tenth the size and cost of most tactical and navigation-grade inertial systems.

Robotic Fighters Coming in on GPS Jan 1, 2006 By: Lisa McAdam

A recent simulated test of military UAVs demonstrated one more envisioned GPS role in military operations. As part of the J-UCAS program, Northrop Grumman performed a test of simulated, simultaneous control of four X-47B UAVs on September 28, 2005, at the Naval Air Warfare Center Weapons Division in China Lake, California.

Hurricane Hunters GPS Dropsondes Trace Katrina's Course Oct 1, 2005 By: Marty Whitford

GPS dropsondes released into the Katrina's eyewall tracked and predicted wind strength, speed, and direction.

The GPS Joint Program Office (JPO) has launched an initiative to shift all work on Modern User Equipment (MUE) to a single contractor, citing budget constraints.
