Testing and adapting In-House developed algos: PDS_005 

Hardware – Software

EPFL Spacecraft Team students developed in-house determination and control algorithms for the attitude of the CubeSat, in the scope of an academic semester project.
This project aims at testing and improving the algorithms by developing an airbearing test bench to simulate the satellite motion, such that both the attitude determination and the control can be verified.
The attitude determination shall also be tested prior to the airbearing testbench on a simple integrated system. The test bench shall be equipped with sensors to monitor the CubeSat motion.

Expectations from the student

The outcome of the project will be presented in the Preliminary Design Review of the mission. 
The student is expected to develop a functional airbearing test bench, the testing procedures and optimize the existing control algorithms. The provided work shall be documented in a report.

Design and prototype an X/S Band antenna (EL) PDS_008

Hardware – Software
Develop and test a prototype for the main antenna for the CHESS CubeSat. This circularly polarized antenna will be used for uplink of commands and downlink of large amounts of data. It shall consist of a single patch or patch array, including feeding network to be connected to a commercial transceiver. Prior experience with simulation of electromagnetic structures (with Ansys HFSS or similar) is of advantage.

Expectations from the student

The outcome of the project will be presented in the Preliminary Design Review of the mission
Output: Antenna prototype including feeding network.
