Wavepoint Research is currently performing a SBIR Phase I project for the Air Force (AFRL/RYRN) sponsored by the GPS Wing of the Space Missile Systems Center (SMC) to investigate the feasibility of providing cooperative handheld location device using signals of opportunity. |
|
| This Phase I effort will show that cooperative receiving devices can determine their locations with good accuracy using only signals of opportunity without a global positioning system (GPS). Using emitters of known location, algorithms for calculating receiver location from cooperative signal processing routines will be developed. The focus of the Phase I effort will be on high-power terrestrial broadcast signals from AM, FM and TV stations. |
By completion of this project, a cooperative handheld location device using signals of opportunity will be developed and demonstrated through modeling by: (1) developing algorithms sufficient for determining TDOA of transmitted signals to cooperative receiver devices; (2) developing algorithms sufficient for determining location of receivers from TDOA information related to emitters of known location; and (3) preparing a detailed computer simulation to characterize performance of the algorithms using signals of opportunity.
