Our group has been taking DiffGPS readings with Ashteck Promark3 DiffGPS equipment for about 9 years with very few problems. However, shortly after April 6 2019 - the date of the Week Number Roll Over - the data our units collected would no longer process in the GNSS software. I could load the rover data files and they would load but if I included the base station data the program would choke during the file loading stage. I could also load the base station data and correct it using the reference station 78 km away but once again it would choke if I loaded the rover data at the same time. I have updated the firmware on all the units and also the GNSS software to version 3.10.07 but no luck. Rinex converter was suggested as something to try but it doesn't recognize the Promark data.
Any suggestions would be helpful.
