I am using a RS2-receiver with RTK getting the correction by NTRIP over the mobile-connection. The output I am consuming automatically over the RS232-port as NMEA-GGA string.
The horizontal coordinates are fantastic. Better than 0.05 meters in both directions.
The height has a constant offset of about 0.8 meters.
Personally, I guess this is related to the geoid.
- Is there an internal geoid in the RS2?
- If yes, is there a possibility to ignore it or to replace it with a local geoid.
The conversation has to happen in the receiver, because the data are not going the ReachView-app.
Looking forward to any ideas and hints,
