The Gurwin-Techsat satellite, designed and built in the Technion-Israel Institute of Technology, proved to be a space long-liver. With six years in orbit, it is here presented as an example of a multi-purpose, reliable microsatellite. A review of its sub-systems and payload performance is given, including attitude and thermal control, solar panels, and scientific equipment. As was demonstrated by the mission, a substantial reduction of the satellite mass, size, and power consumption can be achieved without deterioration of its basic characteristics, such as mission life, payload efficiency,measurements precision, etc. The platform itself, as well as the flight experience gained during its functioning in orbit, can be used in designing and manufacturing similar microsatellites with new and different research payloads.
