Abstract: In one embodiment, a client device generates a location fingerprint. The fingerprint may include various data identified by scanning for WiFi network devices such as the MAC addresses of nearby WiFi access location as well as the respective signal strengths. For each fingerprint location, the client device attempts to use a GPS receiver to scan for GPS satellite signals and identify current GPS latitude and longitude coordinates.

When the client device returns to the location, identified by reviewing the fingerprint, the client device may activate or inhibit the GPS receiver based on the success information of the fingerprint. If the stored data indicates a low success rate, other location identification techniques may be used.

Abstract: A system and method are disclosed to track aircraft or other vehicles using techniques including multilateration and elliptical surveillance. Unlike conventional approaches that use time difference of arrival for multilateration at a fixed set of reception points, this technique allows targets to be tracked from a number of dynamic or moving reception points.

Additionally this technique allows for ADS-B validation through data derived from only two receivers to assess the validity and integrity of the aircraft self-reported position by comparing the time of arrival of the emitted message at the second receiver to the predicted time of message arrival at the second receiver based on the self-reported position of the aircraft and the time of arrival at the first receiver.

Abstract: A method of locating a transmitter is disclosed. A communications link is established between multiple receiving stations and a control station, and used with a calibration signal to calibrate out the time delay of the communications link. A radiated signal from an unknown transmitter is received at a receiving station and sent to the control station over the communications link. The time of arrival is recorded. Upon receiving a user input, the communication link switches from transmitting the received radiated signal to transmitting the calibration signal. The start of calibration signal is timed to begin at the same time across all of the receiving stations. The communication link time delay for each link is calculated by subtracting the start time from the received time, and the communication link time delay is subtracted from the received time recorded for the radiated signal. TDOA calculations are made to locate the transmitter.
