Rover Mode
Rover mode is utilized for taking point measurements using Real-Time Kinematic (RTK) positioning. For RTK to function effectively, a correction source must be available to provide the necessary data to the rover. This ensures that the rover can determine its position with high precision relative to the base station.
Entering rover mode
- Select "Make Rover" in Web UI status page
- Or set boot mode to Rover in Web UI settings page
- Navigate to Rover Page for location marking
Correction sources accepted
- NTRIP casters over the internet (Virtual Reference Stations VRS)
- Lora Radio (Corrections sent over radio from a RoboDot base station)
- CORS stations (for postprocessing using PPK Rover Mode)
- Corrections over BLE
- Corrections over TCP port 1000
- Corrections over Serial* (Contact Us)
Connecting to a VRS
- Connect RoboDot as a Station to a network with internet access.
- In the settings page, open Configure under Remote VRS, enter the caster's details (or paste RoboGNSS-format credentials), and press Save Profile & Use. Each VRS service you use is stored as a named profile — switch services later by just picking from the dropdown. See connection-profiles.
- Press Connect Now, or enable Auto Connect to connect on every boot.
Once connected, the fix type moves through Float to Fixed as corrections are applied. Brief satellite blockages — walking under trees, passing a building — no longer drop the VRS session: the RoboDot keeps the connection alive and recovers the fix as soon as the sky clears.
Marking a location
- On the rover page, enter rod height
- Optional: Add location identifier
- Select "Mark Location"
Point codes: tap a code chip above the Identifier field to prefix the point with a consistent code (e.g. FEN: fence corner). Tapping a different chip swaps the prefix — fast, consistent labeling with no retyping.
You can also mark points without a phone: the touch screen's Survey screen has a Shoot button that records a point at the current fix.
Each recording run writes its points to its own session file (.sht) inside the active job — a comma separated file with the following values:
| Shot Count | GPS Time | Latitude | Longitude | Height(M) | Quality | Ident | Antenna Offset(M) | Pole Height(M) | Obs Length(S) | Ground Elevation(M) | Sats | PDOP | Reference | Vertical Accuracy(M) |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 1 | 2025 02 20 21 42 03 | 32.68456607 | -96.86463903 | 181.1551 | 3D | Robota Hanger 7 | 0.094 | 1 | 15 | 180.0611 | 23 | 1.24 | Disconnected | 1.0406 |
Height(M) and Ground Elevation(M) are ellipsoidal. For sea-level elevations, activate a geoid model — orthometric heights then appear on the Status page and in point exports, always labeled with the model. See Heights & Orthometric Elevation.
To navigate back to a recorded point, see stakeout.
Lora Radio
If the lora radio is enabled in the settings page, RoboDot will receive RTCM3 via Lora from another RoboDot in Base mode on the same frequency, enabling centimeter level precision relative to the base.
