The CADSat mission
In the development of satellites, scientists and engineers have to work together to create the best design based on the objectives of the particular mission. The scientific aims of your mission will directly affect how your CADSat should be engineered. In your submission, you will need to include a description of your scientific objectives – make sure to specify the data you will analyse and the conclusions you aim to draw. Here, you will find an outline of your mission and hints to the hardware components you should include.
Your design concept must measure the following parameters and transmit the data as telemetry to the ground station:
• Air temperature
• Air pressure
Remember, scientific missions require data to be analysed once the ground station has received the transmission, therefore it is important that your design includes a communications module.
The secondary mission for your CADSat must be selected by you. It can be based on other satellite missions, a perceived need for scientific data for a specific project, a technology demonstration for a student-designed component, or any other mission that would fit the CADSat’s capabilities.
Some examples of missions are listed below, but you are free to design a mission of your choice, as long as it can be demonstrated to have some scientific, technological or innovative value.
Some example secondary missions:
When coming up with your mission concept and hardware components, think if there is additional data you would like to retrieve and analyse, e.g.
• GPS location
• Radiation levels
It can be very important for the scientists and engineers to recover their payload, therefore a targeted landing is sometimes necessary. Your CADSat design could include advanced telemetry/telecommand to help navigate a targeted landing. Alternatively your CADSat could incorporate a bespoke parachute or airbag.
Your CADSat can simulate an exploration flight to a new planet, taking measurements on the ground after landing. You should define your exploration mission and identify the parameters necessary to accomplish it (e.g. pressure, temperature, samples of the terrain, humidity, etc.). This may require additional sensors to be included into your CADSat design.
The CADSat casing design is a great way to add some artistic flare. However, all the amazing science is happening using the technology inside. Your CADSat design should show what sensors, electronics and communication hardware that you will use. There are a variety of Consumer-Off-The-Shelf (COTS) hardware available, therefore, you should design your CADSat with your specific components in mind.
