Before You Begin

You'll need:

• A 4G SIM card with data plan installed in your drone
• Network RTK service account from a local provider
• Server address, port, username, and password from your RTK provider

Onboard RTK Setup (Recommended)

This method uses the drone's 4G connection for RTK data:

1. Open DMRGCS app and tap the settings icon (⚙️)
2. Select RTK Settings from the menu
3. Ensure RTK mode shows "Onboard" - if it shows "Ground", tap to switch
4. Enter your RTK service details:
   • Server address (provided by your RTK service)
   • Port (typically 8001 or 8002)
   • Username and password
5. Tap "Get Point" to retrieve available mount points
6. Select your nearest mount point
7. Tap "Set" to save the configuration

Ground RTK Setup

This method uses your remote controller's internet connection:

1. Ensure your remote controller is connected to the internet via WiFi or ethernet
2. In RTK Settings, switch mode to "Ground"
3. Verify your username and password are correct
4. Tap "Get Mount" to retrieve mount points
5. Select appropriate mount point
6. Tap "Connect" to establish RTK connection

Verifying RTK Status

Check your RTK connection status in the app:

• "Network: Connected" confirms internet connectivity
• "Ntrip: auth successfully" confirms RTK service authentication
• GPS status should show "RTK (float)" or "RTK (fixed)" for best accuracy

With RTK active, your positioning accuracy improves from meter-level to centimeter-level, essential for professional surveying work.
