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!

Cost estimates

As with any dream to be realized, there are also economic costs.
We have calculated the costs as follows:
(Note: These costs cover the total of 10 launches and include reserve material, such as balloons, additional cameras, etc..)
€ 3,500 – 12 units 3000g High Altitude Balloons, ropes, strings, insulating materiales  and accessories
€ 4,000 – helium gas cylinders
€ 4,500 – videocameras and accessories
€ 1,500 – APM 2.5 with telemetry and accessories (ArduPilotMega hardware – UAV platform)
€ 2,500 – RC Gliders (for R.T.L.)
€ 3,500 – electronics (Arduino Mega, Sensors, Batteries, Servos, Cables …)
€ 2,000 – smarphones, telemetry kits and accessories (for communication)
€ 3,500 – consultants, lawyers, insurance
€ 1,000 – travel
€ 1,000 – various

The Actarus Project

What is Actarus Project?
The project aims to launch a payload with GPS, camera, sensors and communications to an altitude of more than 38km (125000ft) with the help of a helium inflated balloon, and then get it back with a autonomous paraglider drone so that the payload can return to the launch site.
The final goal of the project is to take pictures, videos, weather data and to prove that is possibile to design and build a simply “Return To Launch” system, suitable for other similar projects.
In fact, although we have seen that it is fairly easy to launch these balloons at high altitudes, the problem of recovering the payload, it is not always easy, especially if you live in an inaccessible and wild area as the one in which we live.
So the main difference between our project and ohter similar projects, is the way the payload will come back to the earth.
Also we would like to try to beat the 53km world record.
All the project is open source, so all information about the hardware and the software used for the missions, will be available to everyone through our website.
We think the technological work behind this project, which is based practically on the Arduino and Android platforms, made available to everyone will mark a step forward in the search for near space, and can be a source by other scientists or hobbist around the world.

Who are we?
We are two friends with a passion for electronics, adventure, and science (and of course make the impossible possible…) 🙂
So we have been playing with some projects (this is not the only one!!!) based on these three passions.
All the projects are designed by us, taking inspiration from other projects that we have found on the net.
The starting points are Arduino, Android based smartphones, and a touch of madness… 🙂

History
All began in late 2011 when we saw a hobby high altitude baloon on a magazine, so we asked each other if we would be able to do something like that.
In some days we had all the stuff for the first very low altitude test launch, and so began the “Actarus Era”.
These tests aims to become familiar with the all the calculations and the necessary tools, and they have produced positive results.
The reasons why we didn’t make high altitude test are economic and legal: before start with a high altitude project we need some more funds (in the test launches we used standard party balloons and low resolution old smartphones) and some permissions issued by E.N.A.C. (sort of Federal Aviation Administration).

The future
So after a break of about a year, during which we continued to work in the background and study the details of our project, we are almost ready for final launches.
This will be through a series of successive launches in which each will provide information for the next launch.
These launches would take place from the month of June 2013.
Now we  just need some funds to realize our project.
If you want you can contribute with just little money: please take a look at this post, or contribute through Indiegogo platform at http://igg.me/at/actarus
Thank you
