Portable reference station for local differential GPS corrections |
摘要 |
A method and system for local computation of information to improve accuracy in a differential Global Navigation Satellite Systems (GNSS). The method comprising: determining a current location of a reference receiver; comparing the current location with at least one stored location; if a resultant of the comparing is less than a selected threshold, identifying as a reference location the at least one stored location, which is closest to the current location; otherwise establishing the current location as the reference location and storing the current location. The method also includes computing the information from signals from one or more GNSS satellites the based on the reference location; and transmitting the information for reception by one or more remote receivers.
