Method and apparatus for geolocation determination |
摘要 |
The disclosure relates to method and apparatus for geolocation determination. In one embodiment, the disclosure relates to a method for detecting an erroneous satellite measurement by a receiver, including the steps of (a) determining an approximate location of the receiver; (b) for each of a plurality of satellites from which the receiver receives a signal: (i) determining a range difference between an expected range between the receiver and the satellite and a measured range between the receiver and the satellite; (ii) determining a median value of the range differences; (iii) determining an offset value between the range difference and the median value; (iv) comparing the offset value with a predetermined threshold to thereby detect an erroneous satellite measurement.
