The device supports three primary operational modes, which can be set as default boot modes. Users can configure these settings to ensure the device always starts in the preferred mode.
Understanding fix quality is crucial for all operational modes. RoboDot provides several fix quality indicators that represent different levels of positioning accuracy:
Fix Type
Explanation
3D
Standard positioning with 2-meter positioning accuracy. Provides the lowest real-time accuracy but can be post-processed in PPK (Post-Processing Kinematic) workflows to achieve high accuracy results.
Float
Using corrections to try to achieve RTK fix. Typically indicates that the receiver is in the process of converging toward a Fixed solution. In this state, the ambiguities are estimated as floating point numbers.
Fixed
Rover has achieved its most accurate RTK fix. Represents high-precision positioning where carrier phase ambiguities have been successfully resolved to integer values, providing centimeter-level accuracy.
Surveyed
Base has been set on a position, either manually or automatically. Essential in base station modes, where the base requires a predetermined position. Note that this position may not be inherently accurate, depending on how it was obtained. RoboDot allows you to either enter a position manually or average the current readings to establish the surveyed position.
For real-time operations requiring high precision, a Fixed solution is generally desired. For post-processing workflows, collecting data with at least a 3D Fix can be sufficient, as accuracy will be improved during the PPK process.
When operating in base mode, establishing an accurate surveyed position is critical for overall system performance where absolute positioning is desired. The quality of the base position directly affects the accuracy of any rovers using corrections from this base.
