WebMay 1, 2024 · To accomplish the assessment, we considered 4 quality indexes for performing the quality check, incluing the multipath effect on L1 and L2 bands, signal-to-noise ratio in both bands, cycle slips, and integrity. Meanwhile, a new reference parameter named regional values for Mexico (RVM) was calculated for the stations situated in Mexico. WebBy using signal quality measures provided by the GNSS manufacturers (HDOP and Positional Quality), the authors will use manufacturers suggestions to create a novel Data Quality Control Criteria (DQCC) to explore the implications of “poor” GNSS signal. This will scrutinise each data point of the GNSS files to verify it meets the signal ...
