Claim 0:
1. A method for determining corrected positions of a global navigation satellite system (GNSS) rover using a GNSS base station and a plurality of GNSS reference stations, the method comprising:
performing a first plurality of position measurements at a first GNSS reference station, the first GNSS reference station being one of the plurality of GNSS reference stations, the first GNSS reference station arranged at a first location while the first plurality of position measurements are determined, the first plurality of position measurements determined using corrections received from the GNSS base station and signals received at the first GNSS reference station from GNSS satellites, wherein the first plurality of position measurements are determined while the first GNSS reference station is stationary;
performing a second plurality of position measurements at a second GNSS reference station different from the first GNSS reference station, the second GNSS reference station being one of the plurality of GNSS reference stations, the second GNSS reference station arranged at a second location while the second plurality of position measurements are determined, the second plurality of position measurements determined using corrections received from the GNSS base station and signals received at the second GNSS reference station from GNSS satellites, wherein the second plurality of position measurements are determined while the second GNSS reference station is stationary;
determining a position of the GNSS rover using corrections received from the GNSS base station and signals received at the GNSS rover from GNSS satellites;
determining a position correction based on the first plurality of position measurements and the second plurality of position measurements;
determining a corrected position of the GNSS rover based on the position of the GNSS rover and the position correction.
