  1. 1. Risk Assessment for Space Debris Collisions

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Kenny Andersson; [2023]
    Keywords : space debris; NASA standard breakup model; satellite fragmentations; satellite fragmentation modelling; space surveillance and tracking; ESA MASTER; collision risk; risk assessment; space situational awareness; rymdskrot; NASA standard breakup model; satellitfragmentering; modellering av satellitfragmentering; inmätning och övervakning av rymdobjekt; ESA MASTER; kollisionsrisk; riskbedömning; rymdlägesbild;

    Abstract : The increasing reliance on space infrastructure and its rapid expansion necessitate the development and enhancement of tools for space debris and fragmentation research. Accurate prediction of the risks associated with satellite fragmentation requires comprehensive understanding of the dynamics involved. READ MORE

  3. 2. Autonomous Orbit Control with on-board collision risk management

    University essay from KTH/Rymdteknik

    Author : Clément Labbe; [2021]
    Keywords : Tests; Autonomous Orbit Control; collision risks; station-keeping; control indicators; Tester; autonom bankontroll; kollisionsrisker; manovrer; kontrollindikatorer;

    Abstract : Many satellites have an orbit of reference defined according to their mission. The satellites need therefore to navigate as close as possible to their reference orbit. However, due to external forces, the trajectory of a satellite is disturbed and actions need to be taken. READ MORE

  4. 3. Integration and validation of a nanosatellite flight software (ESA OPS-SAT project)

    University essay from KTH/Rymdteknik

    Author : Anthony Surivet; [2021]
    Keywords : Flight software; On-board autonomy; Orbit control; Collision risks; Nanosatellite; Flygprogramvara; Inbyggd autonomi; Banreglering; Kollisionsrisker; Nanosatellit;

    Abstract : With the increasing number of satellites operating in orbit and the development of nanosatelliteconstellations, it has become more and more arduous for operators to keep track of every satellitestate, and perform corrective or avoidance manoeuvres. That is why CNES, the French space agency,is developing new algorithms, which aimed at making satellites more self-su cient. READ MORE

  5. 4. Evaluation of Prediction Models in Trajectory Planning for Overtaking Maneuvers.

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Linda Truong; [2019]
    Keywords : ;

    Abstract : Developing autonomous overtaking could enhance safety by more accurate decision making of if, when and how to execute an overtaking and thereby decrease the collision risk caused by the human factor. Trajectory planning is a strategy to plan overtaking maneuvers, where a trajectory is defined as a path containing position, velocity and acceleration information along with time stamps. READ MORE
