==== 4th Semester: Low cost camera for CubeSat - a feasibility study ==== **Semester Topic:** Microcomputer Systems\\ **Group Members: ** Morten Burchard Tychsen, Morten Egelund Jensen, Jens Martin Oddershede, and Simon Just Kjeldgaard Pedersen.\\ **Abstract:**\\ This project concerns the development of a camera system for taking a picture of Earth from a CubeSat. Based on a market survey, a suitable image sensor complying with the requirements for operation in space is chosen. For testing purposes, a lens is chosen, but a comprehensive market survey should be made to select a lens suitable for operation in space. The functionality of the camera system is analyzed using UML use cases. The use cases obtained are take picture, generate thumbnail, and self test. In order to test the camera system, a test system is constructed, based on the Motorola 68000. The test system runs the TS2MON debugger/monitor and communicates with a PC over a RS-232 connection. This forms a platform for designing the interfaces needed for the camera. Hardware and software design of the camera system is modulated by using the use cases and the Rugby meta-model. The hardware and software of the test system works as designed, but it has not been possible to take a picture. It is possible to communicate with the camera, but the resulting data does not resemble a picture. This is possibly due to misconfiguration of the camera. During software integration, faulty memory reads have occurred, which are believed to be EMC related, due to the long buses. Both of these problems are not investigated further, which should be done before the camera can be used on board a CubeSat.
