1	Ground Segment Software Design and Development for Nanosatellite Space Missions Choi, Jin Hyouk 18 March 2013 (has links) For spacecraft development, realizing strong supporting ground segment software is as important as designing the actual hardware component of the spacecraft. This thesis describes the author’s contributions to the ground segment software design and development for nanosatellite space missions at the UTIAS Space Flight Laboratory. Particular emphasis is given to the ground segment software for the CanX-3 and CanX-4/-5 missions. For the CanX-3 mission, several software applications are explored, specifically ground control software for the payload on-board computer and star tracker, and mission planning software. For the CanX-4/-5 mission, its mission monitor and control software, and whole orbit data parser are discussed. For each software application, design considerations and decisions made during the development are explained. Furthermore, detailed discussions on their architectural and graphical user interface design and implementation are presented. nanosatellite ground segment ground software ground station CanX-3 CanX-4/-5 0538

3	Propulsion System Development for the CanX-4 and CanX-5 Dual Nanosatellite Formation Flying Mission Risi, Benjamin 04 July 2014 (has links) The Canadian Nanosatellite Advanced Propulsion System is a liquefied cold-gas thruster system that provides propulsive capabilities to CanX-4/-5, the Canadian Advanced Nanospace eXperiment 4 and 5. With a launch date of early 2014, CanX-4/-5's primary mission objective is to demonstrate precise autonomous formation flight of nanosatellites in low Earth orbit. The high-level CanX-4/-5 mission and system architecture is described. The final design and assembly of the propulsion system is presented along with the lessons learned. A high-level test plan provides a roadmap of the testing required to qualify the propulsion system for flight. The setup and execution of these tests, as well as the analyses of the results found therein, are discussed in detail. aerospace microsatellite nanosatellite propulsion formation flying canx4 canx5 canx-4 canx-5 canx-4/-5 SFL UTIAS cold-gas thruster satellite CNAPS NANOPS nano sulfur hexafluoride SF6 vibration testing spacecraft environmental testing propulsion testing low earth orbit canx2 canx-2 station keeping orbit maneuver orbital station-keeping liquefied cold-gas propulsion micropropulsion engineering space canadian space flight laboratory canadian advanced nanospace experiment PSLV micro-propulsion thruster interferometry ground moving target indicator on-orbit servicing and inspection 0538
