SBIR-STTR Award

This research program develops and demonstrates a ranging method capable of GPS-like accuracy (less than 3 m RMS error) using signals compatible with GSM cellular networks. The method operates without interference with GSM service and can be implemented using standard cellular hardware components.

In Phase 1 of this SBIR program, a signal design method was demonstrated that allows accurate ranging in narrow frequency bands, like those used by legacy communications systems. Suitable bands for this novel method include those used by GSM cellular telephones and by narrowband military radios. Phase 1 results in the GSM band showed very accurate ranging is possible without interference to other users of these systems. This Phase 2 SBIR program, building on the results of the successful Phase 1, has three objectives: extend the Phase 1 ranging results to demonstrate that the method can provide locations as accurate as GPS, demonstrate the flexibility necessary for operational use, and provide an efficient path for the transition of the method to further development and operational use.
