Do you have an up-to-date list of GPS and RTK receivers that are known to work well with your software ?
A list of supported hardware (including GPS and RTK receivers can be found here.
Please note, that when a device isn't listed this does not mean it does not work with our software. It is safe to say that every GPS or RTK receiver capable of outputting NMEA0183 or Garmin PVT data is supported by Hydromagic.
When in doubt, you can always contact our support desk. We are happy to check whether a specific brand/model should work with the software.
