With a unique expertise in the development, calibration, and operation of coherent sensor networks, LGS Innovations is positioned to support high-priority missions through precision geolocation of signals. Our experience with a variety of geolocation techniques and concepts of operation (CONOPS) include those that leverage angle of arrival (AOA), ranging data, signal related information (SRI), and complex ambiguity functions (CAFs).
We have particular expertise with systems that utilize time/frequency difference of arrival (TDOA/FDOA). These solutions enable a small group of coherent sensors to provide nearly instantaneous location estimates for signals of interest, making them especially impactful to our customers’ missions. These sensors and environments can also be heterogeneous (developed and deployed by different organizations without a priori knowledge of the other sensors).
