Telemetry window

When the route is in progress, the telemetry window is shown. This window allows switching between three different views:

• Horizon. This view displays the Horizon and the main telemetry fields.

• Grid. Hides the Horizon and leaves only the main telemetry fields.

• List. Shows the full list of the telemetry fields of the drone. The coding before the name of the field explains the source of the telemetry and consists of the first letters of the source name:

  CONTROL SERVER
  FLIGHT CONTROLLER
  GIMBAL
  CAMERA
  ADSB TRANSPONDER
  WINCH
  HANGAR
  USER
  GPR
  ADSB RECEIVER
  ADSB VEHICLE
  WEATHER_STATION
  VSM
  LIDAR
  RANGEFINDER
  REMOTE ID
  HORIZONTAL OBSTACLE DETECTOR
  VERTICAL OBSTACLE DETECTOR
  OBSTACLE AVOIDANCE
  ALTIMETER

In the first two views the displayed telemetry fields depend on the drone model. They may be the battery charge level, the number of GPS satellites visible, the quality of the downlink channel, and the state of connection to the remote controller and the heading. These gauges will have a white, orange, or red color depending on the charge or the quality of the signal.

Next there are altitude and speed fields:

• Raw altitude – altitude data sent from the vehicle (without any additional interpretation). This value is based on GPS and/or barometer data.
• AGL altitude - shows current vehicle altitude above ground level. The accuracy of this value depends on the digital elevation model of the map for the particular region. The value is calculated thusly: Altitude AGL = Altitude AMSL - Elevation.
• AMSL altitude - shows the current altitude of the vehicle above means sea level. This value is based on Raw altitude data. The value is calculated thusly: Altitude AMSL = Take-off point altitude + Raw altitude.
• Vertical speed - an indication of how fast a vehicle is ascending or descending. A positive value means an increase in AMSL altitude, and a negative means descending.
• Ground speed (Horizontal speed) - horizontal component of the vehicle speed or Ground Speed.

Telemetry is recorded and values are saved to the database. Usually, a vehicle reports its state multiple times per second. All reported data is saved to disk. The telemetry data can take up a large amount of available space.
