Bachelor's degree theses

NOTE: In order to apply for any of the following theses or internships, the candidate must have no more than 3 exams left.

ADCS

Design and implementation of an automatic reorientation system for the Sun simulator of an attitude determination and control dynamic testbed.

A three-degrees of freedom dynamic testbed for CubeSats attitude determination and control is currently available at the lab. The facility enables a disturbance-free rotational motion within an orbit-like magnetic field and solar illumination, which are simulated thanks to an Helmholtz cage and a collimated led lamp.

The Sun simulator is currently mounted in a fixed orientation with respect to the Helmholtz cage. Through the thesis work, the candidate will design and possibly implement an automatic reorientation system for the lamp that:

  • interfaces mechanically and electrically with the current facility.
  • Is capable of adjusting the orientation and intensity of the light source according to a predetermined orbit profile.
  • Minimizes shadowing/interference with the pre-existing installed hardware.

Number of students required1 bachelor.

Requirements:

  • Attended and passed ‘Satelliti e Missioni Spaziali’
  • Attended and passed ‘Fondamenti di Meccanica Orbitale’
  • Good skills with CAD software

COLLISION AVOIDANCE – SPACE DEBRIS

TLE Conjunction screening

Fundamental part of this detector is the fast scanning of the space objects database for close approaches.

In this thesis project you are requested to build a script that perform such a scanning.

More specifically the task is to develop a MATLAB script that, given a target satellite and a set of TLEs, finds "dangerous" minimum distances between the target and other bodies. This work is based on that of Salvatore Alfano and David Finkleman "On selecting satellite conjunction filter parameters".

The student will firstly understand the above mentioned paper and the problem that the work is trying to solve.

Then the searching procedure described therein shall be implemented as it is.

Lastly the student shall modify his script applying two filter modifications for the scanning process:

  • the second filter shall use Minimum Orbit Interception Distance, i.e. MOID as pruning metric (function provided by the supervisor).
  • the third filter shall use "brute force" minimum distance (about MOIDs), i.e. numerical miss distance minimization in time, as pruning metric.

The development of the algorithm shall be subjected to standard numerical verifications using some selected testcases.

 

Number of students:

  • 1 Bachelor degree student

 

Requirements:

  •  knowledge of informatics (and basic experience with MATLAB)
  •  Followed course of spacecraft orbital dynamics or findamenti di meccanica orbitale
