Attitude sensor and actuator interfacing for micro-satellites
(Stellenbosch : Stellenbosch University, 2002-12)
ENGLISH ABSTRACT: The purpose of this thesis was to design and test the interfaces of sensors and actuators. In the
complete Attitude Determination and Control System CADCS) the Interface Control Processor
(ICP) must ...
An aircraft based emulation platform and control model for LEO satellite antenna beam steering
(Stellenbosch : University of Stellenbosch, 2010-12)
ENGLISH ABSTRACT: A joint project between the KU Leuven and Stellenbosch Universities was at
the time of this thesis underway to develop a space borne electronically beam
steerable antenna and the associated ground-space ...
Investigation of a high-speed serial bus between satellite subsystems
(Stellenbosch : Stellenbosch University, 2003-04)
ENGLISH ABSTRACT: The aim of this thesis is to investigate the implementation of a high-speed serial bus based
on the IEEE Std 1394-1995 specification for use in a microsatellite.
Earth observation microsatellites carry ...
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 ...
The design and development of an ADCS OBC for a CubeSat
(Stellenbosch : Stellenbosch University, 2011-12)
ENGLISH ABSTRACT: The Electronic Systems Laboratory at Stellenbosch University is currently developing a fully 3-axis controlled Attitude Determination and Control Subsystem (ADCS) for CubeSats. This thesis describes the ...
Java implementation of AX.25 link-layer protocol for future micro-satellites
(Stellenbosch : Stellenbosch University, 2003-04)
ENGLISH ABSTRACT: This thesis investigates the viability of implementing the AX.25 protocol in Java, for
satellite applications. The AX.25 protocol forms part of the Communications subsystem
of a micro-satellite. It ...
Volumetric data throughput optimisation by dynamic FEC bearing frame length adaptation
(Stellenbosch : University of Stellenbosch, 2010-03)
ENGLISH ABSTRACT: The telecommunications link between a LEO satellite and a rural ground station
with a non-tracking antenna, has a strongly varying link quality and
a short communications window. The satellite acts as ...
Design of an aerodynamic attitude control system for a CubeSat
(Stellenbosch : Stellenbosch University, 2012-03)
ENGLISH ABSTRACT: The Cape Peninsula University of Technology, in collaboration with Stellenbosch University,
is developing a 3-unit CubeSat for a low earth polar orbit. The two main payloads
are a camera and a radio ...
