SYSTEM AND METHOD FOR VERIFYING GLOBAL POSITION INFORMATION

A method and system for providing proof that a GPS (or similar) positioning device obtained in respect of a remote device (102) a position/time/velocity fix at a certain location at a certain time. Satellites (100) transmit continuously varying verification bits, and during a verifiable position fix, the remote device (102) sends a sample of IF data (so containing the verification data) in real time (or very close thereto) to a trusted server (106). A forger of such verification data would need to acquire the verification bits, e.g. by decoding the signals from the satellites, then generate forged data, which would result in an extra few seconds, or a fraction of a second, of delay relative to a genuine position fix, and the server would reject the data as too late. Thus, only a real device (102) in the location claimed can produce this verification data at the time it was received by the server (106).

In an example of a method of the invention, a first pseudorange to a first SPS satellite is determined, and an approximate location of the SPS receiver is determined. An estimated pseudorange for a second pseudorange to a second SPS satellite is determined from the approximate location and a satellite position of the second SPS satellite. The SPS receiver then searches for SPS signals from the second SPS satellite in a range determined by the estimated pseudorange. Typically, this method reduces the search time to initially acquire SPS signals from the second SPS satellite, and the estimated pseudorange is not based on a previously determined pseudorange for said second SPS satellite.

DEAD RECKONING-AUGMENTED GPS FOR TRACKED VEHICLES

The invention relates to an apparatus and method for augmenting the 3 dimensional position information obtained from the NAVSTAR satellite-based global positioning system ("GPS") system. Such systems can be impacted by physical obstacles that prevent the receipt of the satellite signals or as a result of sun spot activity that introduces noise into the signals thus causing them to become intermittently unavailable and/or making them less accurate in the course of normal operation. Therefore, an improved positioning solution that can operate under such poor GPS operational conditions is needed. The apparatus and method of the invention augments GPS with dead reckoning techniques when GPS signals are unavailable or inaccurate. The apparatus and method of the invention demonstrates highest value when applied to blasthole drill positioning applications in open-pit mines.

ESTIMATING AIRCRAFT OPERATIONS AT AIRPORTS USING TRANSPONDER DATA

A thorough understanding of aircraft operations counts at airports is helpful due to the use of those counts in the planning and design process and in the allocation of funds for improvement. Methods of counting aircraft operations at airports lacking full-time personnel are typically based on conventional statistical sampling using relatively small sample sizes due to the inherent difficulty and expense of positioning acoustic or pneumatic counting devices at those airports for extended periods of time. Such methods are often inaccurate because of the lack of sufficient representative samples. A means of counting operations using a combination of Mode C, Mode S, and ADS-B extended squitter aircraft transponder data received using a 1090 MHz software-defined radio system is disclosed herein. The increasing presence of such signals in both controlled and uncontrolled airspace around airports, due to a recent federal mandate that all aircraft in certain types of controlled airspace be equipped with ADS-B Out capability by 2020, lends itself to the measurement of operational parameters associated with the related aircraft. The 1090 MHz signals are received passively; i.e., there is no interrogation from the field-deployed device. The resulting sample counts are typically larger than those determined through conventional data collection procedures. In one aspect, these sample counts are applied to a Bayesian statistical estimation technique, which produces an improved estimate of operations. 1. A method for estimating the operation of an aircraft at an airport , comprising:providing at an airport an antenna having an input adapted and configured for receiving a radio signal and an output in electrical communication with a computer having memory;receiving first radio data from a transponder of a first flying aircraft;determining from the first data the likelihood of the first aircraft landing at the airport; andautomatically logging by the computer in memory that the ...
