Design and Development of Generic Nanosatellite Bus Ground Control Software Suite

Choi, Mirue 16 December 2010 (has links)
This thesis describes, in chronological order, the design and implementation of four separate ground control applications for use of the Generic Nanosatellite Bus, a multi-purpose satellite platform developed at the UTIAS Space Flight Laboratory. A direct ground control application and time-tagged remote control application are used to provide full control over a Generic Nanosatellite Bus satellite for short and long term operational and testing purposes. Similarly, a direct control application and a scheduling application are implemented for the control of the payload computer on CanX-3 BRIght-star Target Explorer, a stellar-observation satellite based on the Generic Nanosatellite Bus platform. This thesis goes into details on how the display and control interface is implemented and used, what set of actions are taken to create and interpret packets exchanged over a communications link, and what precautions are taken in the face of expected issues.

The design and construction of the front end section of an L-band receiver for nano- satellite application

Louw, Etnard January 2015 (has links)
Thesis (MTech (Electrical Engineering))--Cape Peninsula University of Technology, 2016. / Optimum communication can only be achieved with a very sensitive front-end section in the receiver on a satellite because the transmitted signal from the ground station must travel hundreds of kilometres through the earth's atmosphere to a low earth orbit (LEO) satellite. This dissertation presents the design of the front end section of the receiver suitable for use in a nano-satellite. Specifically, various transistor technologies are evaluated by designing five low noise amplifiers to determine the optimum performing amplifier. The bandwidth of the front end section was controlled by designing coupled line microstrip filter. For consistency, the same design technique was followed in the design of each LNA. Simulations were performed and the results were compared to the actual measured results of the constructed amplifiers to facilitate conclusions to be made. Design specifications for the LNAs were obtained from the F'SATI Space CubeSat Programme Technical Specification document. To control the bandwidth of the front end section, various types of band-pass filters were investigated, resulting in a coupled line band-pass filter being simulated and implemented. The simulated results were compared to the measured results of the constructed filter. In the final stage of this dissertation, comparisons of each amplifier’s performance were made, resulting in the final recommendation for this project.

In-situ monitoring using nano-satellites : a systems level approach

Dixon, Benjamin Deon January 2015 (has links)
Thesis (MTech (Electrical Engineering))--Cape Peninsula University of Technology, 2015. / Traditional satellite systems employed for use with in-situ monitoring systems are large satellites that have a long development time, high cost and complex sub-systems. The end use of relaying data for in-situ monitoring becomes a costly application for the end user. Shifting this application to make use of nano-satellites, such as CubeSats, for data relaying will make the application more attractive to the end user when measurements are required outside existing ground based communications infrastructure. CubeSats are small, simple satellites that yield a short development time and very low cost compared to conventional satellites. Their sub-systems are generally built from off the shelf components. This keeps the designs simple, manufacture cost low with the potential for flying the latest technologies. This research set out to analyse various scenarios related to in-situ monitoring governed by parameters such as the maximum revisit time, satellite orbit altitude, quantity of sensor nodes and data quantity relayed in the system. A systems level approach is used to analyse each designed scenario using a simulation tool called Systems Tool Kit by Agilent Graphics Incorporated. The data acquired for each scenario through simulation was validated using theoretical approximation methods, which included parameters such as coverage potential, total node access time, communication link performance, power resources, memory resources, access time and number of ground stations. The focus was put on these parameters since they are the main constraints when designing a system using nano-satellites. The outcome of the research was to create an analysis reference for designing an in-situ monitoring system using nano-satellites. It outlines the methods used to calculate and simulate each of the constraints governing the system. Each designed scenario showed satisfactory performance within the defined parameters and can be practically implemented as a reference for designing similar systems. / National Research Foundation / South African National Space Agency
