1. Space Rider System: GNC and System Model Improvements
Master-uppsats, KTH/RymdteknikSammanfattning : As part of a continuous trend of the space sector for obtaining higher performance space science and Earth observations, there is an increasing demand for higher requirements in pointing accuracy and disturbance prediction. The Space Rider System (SRS) is a Low Earth Orbit (LEO) reusable vehicle that aims at answering to that demand. LÄS MER
2. Comparison of Control Approaches for Formation Flying of Two Identical Satellites in Low Earth Orbit
Master-uppsats, KTH/RymdteknikSammanfattning : Formation flying of satellites describes a mission in which a set of satellites arrange their position with respect to one another. In this paper, satellite formation flying guidance and control algorithms are investigated in terms of required velocity increment Delta-v, and tracking error for a Chief/Deputy satellite system.

3. Development of a Low Earth Orbit Mission Preliminary Analysis Tool
Master-uppsats, KTH/RymdteknikSammanfattning : The objective of this project is the development of a mission analysis tool for the nanosatellite company GomSpace Sweden. Although there are many existing software, they can be quite complicated and time consuming to use. LÄS MER
4. A feasibility study for a satellite VHF Data Exchange System (VDES)
Master-uppsats, KTH/RymdteknikSammanfattning : Transportation across the globe's oceans increases every year and is expected to keep increasing in the following decades. Consequently, there is a need to establish communication over the horizon through the Automatic Identification System (AIS) and the Very High Frequency (VHF) Data Exchange System (VDES), still in development, to track and communicate with vessels all over the globe regardless of the distance from shore.

5. Innovative Solutions for Satellite Conformity to Space Debris Mitigation
Master-uppsats, KTH/Farkost och flygSammanfattning : This thesis presents the work I have accomplished during my 6 months internship in Altran Research more precisely inthe Space Innovation Unit in Cannes, France. This period as trainee was also the conclusion of the double degree program I followed in Aerospace Engineering at KTH, the Royal Institute of Technology of Stockholm, Sweden. LÄS MER
