Common Applications

Use RoboDot as a local RTK base for a drone, as a rover for ground control points, or as a repeater to extend a correction link.

RTK Drone Integration

RTK lets a compatible drone geotag images relative to your base position. Absolute accuracy depends on the coordinates assigned to the base.

First connect the controller to the RoboDot wifi, then connect or configure the Custom RTK network in the controller. Use the following credentials:

• Host: The IP on your RoboDot screen, typically 192.168.4.2
• Port:10,000
• Mount Point: X
• User: X
• Password: X

Reference this YouTube for an example with the DJI M3E.

Drone controllers with web browsers can be used to access the Web UI.

Benefits

• Accurate image geotagging
• Enhanced navigation
• Local base advantages over online VRS

Setup Options

1. Relative Positioning:
   • Place RoboDot
   • Connect drone controller to RoboDot Wi-Fi
   • Use Auto Survey or Average from GPS
2. Absolute Positioning:
   • Follow relative steps
   • Add base position coordinates
   • Option: Connect via shared access point
3. Shifting:
   • Operate under Relative Positioning steps
   • Post flight shift images using RoboDot Utility

Long Range Operations

Keep one base position for the project and use a RoboDot in Repeater mode to carry its corrections farther. LoRa range is up to 1 km with clear line of sight; terrain and obstructions reduce it.

Reference this Youtube on how Repeater mode works.

Ground Control Points

Ground control points are commonly used in photogrammetry for map correction and referencing. GCP coordinates can be obtained in many ways including:

Static Observations

RTK Rover Mode

RTK Drone and GCP Collection Combined

Example: RTK Flight with GCP Collection post flight

1. Follow the RTK drone integration steps
2. Complete drone flight
3. Select the appropriate Base Reference:
   1. Single RoboDot options:
      1. Switch to Rover Mode with VRS
      2. Record the Rover observations for PPK processing
   2. Dual RoboDot option:
      1. Use a second RoboDot as Rover with Lora Radio to reference the base
4. Collect GCPs with the Rover
