PROBLEM TO BE SOLVED: To provide a signal deformation monitor for a GNSS ground based augmentation station.SOLUTION: A signal deformation monitor comprises; a CCD monitor stage communicably coupled to a plurality of GNSS reference receivers, where the CCD monitor stage inputs raw pseudorange code measurements and accumulated delta range carrier measurements from each of the plurality of GNSS reference receivers; and a Code Carrier Divergence-High-Pass Filter (CCD-HPF) monitor stage communicably coupled to the CCD monitor stage, where the CCD-HPF monitor processes each of a plurality of low-pass filtered divergence rate measurements produced by the CCD monitor stage through a high-pass filter to calculate an averaged CCD-HPF monitor divergence rate. The signal deformation monitor outputs an exclusion signal associated with a GNSS satellite when the averaged CCD-HPF monitor divergence rate exceeds an exclusion threshold. |
