GPS 2D Distance & 3D Range

      Comments Off on GPS 2D Distance & 3D Range

OpenTX

Calculated sensors take values from real sensors and output data based on calculations using data from those sensors.

Displays

  • Distance on the ground
  • Range accounting for altitude above the ground

Formula

  • Distance

The distance formula uses the initial and current GPS positions to calculate the distance.

A variation of distance is range which uses the same formula but accounts for altitude from an altitude sensor.
