  1. 1. Combined Heuristic and Statistical Methodologies applied to Maneuver Detection in the SST Observation Correlation Process

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Arvind Mukundan; [2020]
    Keywords : Space Situational Awareness; Two Line Elements; Simplified Perturbations Model;

    Abstract : In this project, an algorithm has been proposed to detect a satellite’s maneuver by comparingthe orbital elements observed from the two line element data and the orbital elements propagatedwith the help of Simplified perturbations models. A set of TLE data for an object orbiting Earthcontains a specific set of orbital elements. READ MORE

  3. 2. Detection of in-plane orbital manoeuvres from a catalogue of geostationary objects

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Phuong Linh Ngo; [2020]
    Keywords : manoeuvre detection; geostationary orbit; perturbations; filters; Two-line elements; station keeping;

    Abstract : The number of man-made space objects is dramatically growing nowadays. The continuous monitoring and studying of these objects are necessary to keep their number under control and ensure safe space operations. READ MORE

  4. 3. 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.

  5. 4. Hunting for Planet Nine by its perturbations on the Main Asteroid Belt

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Albin Jonsson; [2019]
    Keywords : Planet Nine; Main Asteroid Belt; Perturbations; evection resonance; libration; Physics and Astronomy;

    Abstract : In recent years, scientists have found unconfirmed evidence for a ninth planet in the solar system at a very wide orbit. The parameters for this planet are poorly constrained. Current estimates mostly come from the effect the planet has on trans-neptunian objects. READ MORE

  6. 5. Development of a Low Earth Orbit Mission Preliminary Analysis Tool

    University essay from KTH/Rymdteknik

    Author : Giada Staniscia; [2019]
    Keywords : Mission analysis; CubeSat; Propulsion; Low Earth Orbit LEO ; Perturbations; Atmospheric drag; Earth oblateness.;

    Abstract : 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. READ MORE
