1. 1. Flight Dynamics Software Industrialisation for Inclined Orbits

   Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Författare :Pierrick Houede; [2023]
   Nyckelord :flight; dynamics; software; FDS; geostationary; orbit; station; keeping; uncontrolled; inclination.;

   Sammanfattning : The geostationary orbit has many applications for Earth observation and telecommunications. Like all satellites, spacecraft in this type of orbit are affected by perturbations. These perturbations can modify the satellites trajectories and, without control, deviate them from their target position. LÄS MER

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

   Master-uppsats, KTH/Rymdteknik

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

   Sammanfattning : 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. LÄS MER

4. 3. Methods to operate and evaluate the performance of a cold-gas CubeSat propulsion system on a magnetically stabilised satellite

   Master-uppsats, KTH/Rymdteknik

   Författare :Victor Alberto Gonzalez Marin; [2020]
   Nyckelord :Propulsion system; CubeSat; Performance; Operating procedure; Mission experiment; Framdrivningssystem; CubeSat; Prestanda; Driftsrutin; Driftprov;

   Sammanfattning : Propulsion systems allow satellites to perform many functionalities in space, such as orbital station keeping, reentry control, attitude control, orbital transferring, rendezvous operation, and even more thrilling, interplanetary travel. Indeed, propulsion systems in satellites have fostered a new favourable era of space exploration and application, therefore, detailed processes to operate propulsion systems need to be developed so that space missions, carrying this valuable system, are completed successfully.

5. 4. Detection of in-plane orbital manoeuvres from a catalogue of geostationary objects

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

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

   Sammanfattning : 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. LÄS MER

7. 5. Model Predictive Control for Six Degrees-of-Freedom Station-Keeping of an Underwater Vehicle-Manipulator System

   Master-uppsats, KTH/Reglerteknik

   Författare :Christian Ernst Siegfried Koch; [2017]
   Nyckelord :;

   Sammanfattning : Underwater robotics are a reliable and ecient mean for exploration and surveysin a submarine environment. Albeit, intervention tasks, e.g. installationand maintenance, require the expansive and hazardous deployment of professionaldivers. LÄS MER
