GPSMAP 66 devices are capable to record GNSS raw observations in RINEX format. And the GPSMAP 66sr with its GPS/Galileo dual-frequency observations is especially suited for highly accurate GNSS positioning in post-processing. We thoroughly tested the GNSS performance of GPSMAP 66sr and published a paper titled "Garmin GPSMAP 66sr: Assessment of Its GNSS Observations and Centimeter-Accurate Positioning" which can be found under DOI 10.3390/s22051964. Has anybody else gained experiences with highly accurate positioning of the GPSMAP 66sr based on post-processed GNSS observations? LW
