[SIGNALS exclusive] The results from the GPS receiver testing sponsored by would-be wireless broadband provider Ligado are in. A review of the nearly 600 pages of data and analysis suggests that a number of GPS receivers can - by the firm's chosen, but somewhat controversial technical standard - operate in the presence of the company's proposed wireless signals.

The Senate Armed Services Committee zeroed out the Pentagon's $393 funding request for the new GPS ground control system during its May 11 markup, asserting that the program's cost overruns - with a total cost that may reach $5.3 billion, up from an original $1.5 billion - had breached the Nunn-McCurdy Act.

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.
The seeming efficiency of having unmanned aircraft carry the same GNSS-based collision avoidance transmitters required for manned aircraft has generated a lot of interest as a possibly safe way to easily integrate unmanned aerial vehicles (UAVs) into the nation's air traffic control system. (more)
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.
