Launch postponed to June 22 (or 23)

In these last days we have dedicated ourselves assiduously to planning the final details and in particular the forecasts on the trajectory.
At the present day, at the date of June 21 the launch will not be possible, si it will be postponed to a date between June 22 and June 25 (at the moment the most likely date is June 22 or 23)
It can also be a slight shift of the place.
The forecasts are reliable approximately 24 hours before the launch, so the final date will be known only on the day before the start of the mission.
You will be informed through this site, as soon as we have a stable forecast concerns the trajectory of the launch.
We should remember that these shifts are related mainly to increase the chances of recovering the data, because judging by the current, launching on 21, our payload would end the Austrian Alps, complicating or making impossible the recovery.

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.

59 days to go! We have planned a date for the first launch! (21/06/2013)

We have set the date for the first launch: if all goes well, if all goes well the launch is scheduled for June 21, 2013, at 10:30 am in the morning.
We are proceeding with the tests and experiments, as well as the drafting of the code of the on-board computer.
In the meantime, we sent the requests for authorization to the competent authorities …
Stay tuned!
