"Thermal Analysis and Test of Cubesat."
Description: In the Frame of CELESTA project, a basic thermal model has been developed. It is now important to finalize the thermal model and to perform test in order to validate the thermal design.

Objectives:

Perform a small bibliographic research on the specific aspect of satellite thermal design. If needed, “get up to speed” on the physics of thermal transfer and lumped parameter calculations.
Take over the model already existing and improve it.
Verify that the model is correct by performing a series of test cases to be defined with CSU engineers.
With the help of other students and system engineers, define a realistic in orbit hot case and a cold case to be calculated.
Based on the results, suggest improvement and modification necessary to the CubeSat thermal design.
Establish a test plan to measure physical thermal parameters (conduction, dissipation, etc…) on samples.
Conduct the thermal test with the thermal vacuum chamber available at the CSU Montpellier
Analyze the test results and write the test report

"CELESTA Cubesat Qualification Test."
Description: In the Frame of CELESTA project, an engineering model is built and the software is coded. Later the flight model will undergo many different environmental tests. At the beginning and in the end of the test campaign, it is important to perform a “Mission Test” with the ground segment to qualify the satellite for flight.

Objectives:

Perform a small bibliographic research on the specific aspect of satellite design, assembly and verification.
Read and understand the mission and satellite documentation.
With the help of other students and engineers, defined the Mission test procedure objectives.
Write a test plan to describe the test set-up.
Develop and write the test procedure. The procedure will be developed and tested on the CELESTA Engineering Model.
If the results are good, it will be possible to perform it on the flight model.
If time and student level allow, it will be possible to start the development of the test to be performed during the Thermal Vacuum Cycling which aim at validating the overall system design performance under temperature.

"Mechanical Analysis of CELESTA Cubesat."
Description: The mechanical design is performed by students of the CSU. In order to verify the design compatibility with the launcher, it is necessary to perform mechanical calculation to find the stress applied during random vibration and the resonance frequency of the structure. Later on Engineering model and flight model will be tested.

Objectives:

Perform a small bibliographic research on the specific aspect of satellite mechanical design.
Create a simple mechanical model of the satellite structure in a dedicated mechanical analysis software.
Perform mechanical analysis for the random vibration level specified by the launcher.
Find the resonance mode(s) and frequencies of the satellite structure.
Update the model with other parts of the satellite and repeat the random vibration analysis and the resonance calculations.
If time and student level allow, it will be possible to start the development of the Engineering Model mechanical test with the aim to validate the structure.
