# 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 <a href="#entering-rover-mode" id="entering-rover-mode"></a>

1. Select "Make Rover" in Web UI status page
   1. Or set boot mode to Rover in Web UI settings page
2. Navigate to Rover Page for location marking

## Correction sources accepted <a href="#correction-sources-accepted" id="correction-sources-accepted"></a>

1. NTRIP casters over the internet (Virtual Reference Stations VRS)
2. Lora Radio (Corrections sent over radio from a RoboDot base station)
3. CORS stations (for postprocessing using PPK Rover Mode)
4. Corrections over BLE
5. Corrections over TCP port 1000
6. Corrections over Serial\* (Contact Us)

## Marking a location <a href="#marking-a-location" id="marking-a-location"></a>

1. On the rover page, enter rod height
2. Optional: Add location identifier
3. Select "Mark Location"

Points are saved in a shot (.sht) file which is 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                   |

## Lora Radio <a href="#lora-radio-1" id="lora-radio-1"></a>

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.
