METHOD FOR DETERMINING THE LOCATION OF A GPS RECEIVER USING AN ESTIMATED REFERENCE TIME |
摘要 |
A method for determining the location of a satellite receiver. The method begins by selecting a trial time for use in calculating a presumed location of the receiver using at least four satellites. The presumed location is calculated based on the selected trial time. A first range from the presumed location to a fifth satellite is calculated and a second range from the presumed location to the fifth satellite is measured. A comparison is then made between the first range to the second range. If the first range is unequal to the second range the presumed location is not the actual location. A new trial time is selected and the method is repeated. When the first range and the second range are substantially the same then the presumed location is the actual location.
