    Abstract:
    
    Satellite technology has been in development since the early 1980\'s in South Africa.  Significant government investment led to the establishment of environmental testing facilities and a complete system engineering and subcontractor industry capability.  In 1992 the Sunsat program was initiated from a micro-satellite perspective.  It is an imperative in terms of satisfying national imperatives of today, to establish a cost effective basis for utilising space.  The ZASat 1 Pathfinder mission is a first step in establishing a long term satellite program in South Africa. 
    
    Since 1994, space activities in South Africa have been the culmination of a number of private initiatives.  From a completely indigenous technology base, the Sunsat micro-satellite demonstrated the integration of the capability in the South African industrial base into a cost effective, micro-satellite remote sensing mission.  Other initiatives included the cosmonaut Mark Shuttleworth.  The first national space development after Sunsat at a national level, is the MSMI satellite imager project in conjunction with Flaanders.
    
    << Dieselfde boodskap, maar ander inhoud – nog te skryf>> Developing nations have taken the route of technology transfer programs and as such South Africa is a keen partner for future joint technology development and know-how transfer programs.  In particular South Africa has been building on the many decades of electronics, optics and mechanical industry infrastructure developed as part of the drive for self-sustaining defence system development and manufacture.
    
    ZASat 1 is based around the 60kg MMSat satellite of SunSpace with a ground spacing distance of 6.5m GSD.  The satellite is a new generation technology taking advantage of the innovation in sensor and digital technology.  
    
    The paper will start with an overview of the heritage of the ZASat 1 Pathfinder, followed by a mission analysis and continue with an overview of the system architecture.  The key space craft parameters are reviewed before concluding with the expected outputs of the program.
