  1. 1. Space Rider System: GNC and System Model Improvements

    University essay from KTH/Rymdteknik

    Author : Simon Vial; [2022]
    Keywords : Space Rider System; Disturbance Modelling; Maneuver Optimization; Space Rider System; Modellering av Störningar; Manöveroptimering;

    Abstract : 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. READ MORE

  2. 2. Comparison of Control Approaches for Formation Flying of Two Identical Satellites in Low Earth Orbit

    University essay from KTH/Rymdteknik

    Author : Hasan Basaran; [2020]
    Keywords : Aerospace; Chief; Control; Deputy; Feedback Linearization; Follower; Formation Flight; Fuel Consumption; Guidance; Leader; Model Predictive Control; Relative Orbit; Rendezvous; Sliding Mode.;

    Abstract : 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.
