Where are all of our experimental data get stored?

The experimental data regarding mission ATLAS1 and the ones from the MCC Software (GPS, accellerometer, gyroscope, magnetometer, temperatures, battery charger, solar panels, active procedures on the comand scheme, ...)  will be memorized on a SD card which is contained inside the module, but the same data will be send via radio.

Why sending data via radio? The craft might fall into water or get lost and there isn't a possibility to retreive the data.

By sending the data via radio to the MCC there is the possibility to:

  • save them without loosing them
  • track the flight and to interact with the craft (by sending some comands) in case of critical scenarios correlated to some electronic malfunctions.

The following image represents the comunication radio procedure.

Recently (3 may 2014) we are waiting to receive from competed departments, data regarding the frequencies used also  for our project. Our authorization regarding radioamaterurial frequencies got aborted since the use of the transmissions are different from the propagation studies (we are going to use radios as a comunication procedure and not as an instrument to study the radio waves).

In this sector we need plenty of help: fortunately, during the Radio Fair in Pordenone, multiple groups interested in the study of radios where very glad to help us out in the radio comunications.

If someone would like to joing our crew, come forward! Write to us!

 

 

ATLAS 0: the electronic diagram

ATLAS0 circuiteria

In ATLAS 0 , which is the first mission of our project, his electronic circuit is originary from Italy: the electronic diagram is called Arietta G25 from AcmeSystems.

In this interesting and small diagram we interfaced these following sensors:

  • 8 sensors to retrieve the temperature positioned on each side of the craft ( shaped as a  truncated pyramid with an octagonal base)
  • 1 temperature sensor  inside the module
  • 4 pressure sensors 
  • 1 GPS
  • 1 accellerometer 3 axis
  • 1 magnetometer 3 axis
  • 1 gyroscope

The sensors that we have used where:S

In the project we have added a buzzer and a button to shut down the system. The buzzer will be activated via software during the descent of the craft to warn it's presence and to avoid the impact on the people. The buzzer will help the crew to locate the module.

The button will disactivate the buzzer. This system was installed to avoid the distruction of the craft from a person caused by it's loud buzz.

StratoLab changes software for drawing electronic circuit diagrams

The stratoLab crew changes software for drawing electronic circuit diagrams used for our project.

We are substituting KiCAD with esayEDA. 

This change is NOT due to difficulties and malfunctions related to the first program, but because it’s more practical to share and to disclose the diagrams.

easyEDA is a web based platform that allows for building electronic circuits, to create a mock up of it and the final design of the printed circuit board without downloading or installing a software on a personal computer (there is also the Web App for Chrome). The portal of this platform gives the possibility to work as a team (where more than one person can work at the same time on the equal project). The standard form service is free and allows users to build many public projects (including 2 private ones).

Below you can find the link of EasyEDA dedicated to the crew members of StratoLab.

KiCad: our developement environment regarding the electronic circuits

One of the aims regarding the project is sharing and for this reason every mission has a it's department, containing the electronic diagrams which everyone can view it.

We chose the software to project the electronic diagrams and to share them with the entire crew in order to make them visible and also to edit them.

Kicad 3dviewer

We chose KiCad!

 

KiCad it's composed by a bunch of open source programs dedicated on the electronic diagrams project (Electronic Design Automation) and printed circuits (PCB) which can be installed on linux, mac and windows computers.

This suite is free (so you can download it without purchasing licenses) and can be installed almost on all the platforms on the market.

The developer group of this software is optimizing it and making it more professional (it can also visualize the 3D vision of the project!)

The most important thing of this software it's his documentation.
