Strategies for the control of a satellite with thruster misalignment
(Stellenbosch : University of Stellenbosch, 2006-03)
This project investigates two problems related to satellites that contain cold gas thrusters and reaction wheels. The first problem concerns the estimation of the thruster force response to a pulse command. An optimal data ...
Control moment gyro actuator for small satellite applications
(Stellenbosch : University of Stellenbosch, 2005-03)
The aim of the thesis is to design a Control Moment Gyro (CMG) actuator which can be used in small satellite applications. The hardware and software of the CMG has to be designed according to specifications given. A ...
An LDPC error control strategy for low earth orbit satellite communication link applications
(Stellenbosch : University of Stellenbosch, 2009-12)
ENGLISH ABSTRACT: Low earth orbit (LEO) satellite communication presents a unique environment which inherently di ers from most other communication channels. Due to the varying orbital patterns of LEO satellites the link ...
Reusable software defined radio platform for micro-satellites
(Stellenbosch : Stellenbosch University, 2008-03)
This thesis describes the design and implementation of a software platform for software defined radio (SDR). This platform was to form part of an experimental satellite payload. Several other experiments were also housed ...
An investigation of satellite maneuvering and orientation strategies using an air bearing table
(Stellenbosch : University of Stellenbosch, 2005-12)
In this thesis, the maneuvering and orientation of an inspection/service satellite is investigated. This thesis will demonstrate a simplified satellite maneuver around another satellite (for docking purposes). This is ...
Attitude determination and control system of a nanosatellite
(Stellenbosch : University of Stellenbosch, 2007-12)
The aim of this project was to design and test a partial attitude determination and control system for a nanosatellite. The reaction wheel system was designed and tested as an actuator for the nanosatellite. This reaction ...
