1. A method of preparing GNSS reference data for processing data acquired by a GNSS receiver at times corresponding to first intervals, comprising:

  • a. Accessing reference data having measurements taken at times corresponding to second intervals longer than the first intervals,b. Determining a geometric component for each measurement,c. Producing for each measurement a geometry-free residual by subtracting the geometric component from the measurement,d. Interpolating the geometry-free residuals to produce interpolated residuals for times corresponding to the first intervals,e. Determining a geometric component for each time corresponding to an interpolated residual,f. For each time corresponding to the first intervals, combining the interpolated residual for that time with the geometric component for that time to produce an interpolated reference measurement for that time.
