Actarus XI – Final goal of the mission

We are just 18 days away to the launch of Actarus XI (this is the final name of the mission), and it is time to publish the details of the mission, in terms of objectives and the equipment used.
With this post we begin to analyze the objectives of this first launch that will serve mainly to collect data and photos, useful for subsequent missions.
In particular, in addition to performing shooting photos and video will be logged (saved in a log file on sd card), the following information:

  • Latitude
  • Longitude
  • GPS Altitude
  • Internal temperature
  • Outside temperature
  • Atmospheric pressure
  • Acceleration in three axes x, y and z

The processing of these data make it possible to understand and evaluate a range of essential information for subsequent missions, in particular:

  • reliability of the prediction on the trajectory
  • rate of climb
  • rate of descent
  • lateral acceleration (so in essence the strength of winds)
  • capacity of the thermal insulation
  • battery life

It will then be temporarily excluded from the objectives of the mission, for weight problems, the assessment of the impact of low temperatures on the servomotor (which will control the direction of the drone) and solar radiation suitable for the production of energy.
