[SIGNALS exclusive] As the contractor for the new GPS ground system works its way through a make-or-break 90-day evaluation period, the U.S. Air Force (USAF) is weighing whether it should look at leapfrogging past that program and shifting control of the newest GPS satellites to a new common ground system for Air Force space assets.

u-blox addresses the demand for lower priced high precision technology ideal for UAVs and guidance robotics. The demand for lower-priced, high-precision technology is growing rapidly, as evident in the areas of precision agriculture, UAVs, and robotic lawnmowers. However, due to size, power, and cost restrictions, existing high precision solutions have been unable to meet the demands of these markets.
Addressing a long-unfulfilled presidential mandate, the Space-Based Positioning, Navigation, and Timing (PNT) Executive Committee (ExCom) has taken on reponsibility for initiating a process to identify and develop requirements for a complementary national PNT, in effect, a backup system to GPS in case of outages from natural or man-made events.

DoT Seeks Receivers for Long-Awaited ABC Interference Tests
Federal testing is about to begin to determine how much interference GPS receivers can tolerate from their spectrum neighbors. (more)
Imagine the impact of a low-cost true north gyrocompass navigation solution on small ROVs and AUVs. Researchers at Johns Hopkins University tested a commercial KVH inertial measurement unit, and found results both promising and directly applicable to static instrument deployment. Read the paper on the experiment, and discover KVH's new GEO-FOG 3D inertial navigation system which includes a built-in north-seeking algorithm.
