Abstract

Several African nations have embarked on indigenous space programs based on small satellites with the objectives of reaping the benefits of remote sensing information, driving national development of technological expertise, and fostering education through participation and inspiration. In particular, South Africa has launched a comprehensive program which so far has resulted in the successful launch of SUNSAT and the production of various satellite components and complete systems manufactured for export.
Currently a technology demonstrator designated ZA-Sat Pathfinder scheduled for launch in 2006 is being completed. It will blaze the trail for the next generation remote sensing platform of the 200 kg class, built around a sophisticated hyperspectral imager deemed the Multi-Sensor Microsatellite Imager (MSMI) which is capable of providing images of high spatial and spectral resolution in various bands.
The paper summarizes the assessment study which was carried out at the University of Stellenbosch, South Africa in cooperation with the Technical University of Munich, Germany. The point of departure for the study is marked by the requirements posed by agricultural applications in South Africa. It then carries on to develop a baseline design of a satellite bus and its subsystems suitable to carry the MSMI instrument and meet the agricultural and other objectives of the mission. A typical operational profile is discussed and estimates of performance in terms of benchmark figures, such as area imaged per day and revisit times, are given.
Finally, it is considered how multiple similar platforms based on MSMI can be operated in a constellation to expand the capabilities from a South Africa specific system to an African Resource Management (ARM) constellation, jointly implemented by the African nations with space capabilities and addressing the particular needs of the continent.
