CONTRIBUTION OF SAFT 1 Scope. This technical note presents what type of electrical power sources could be used on board a Powersat demonstrator. Constraints and objectives take into account the situation after the Eurospace Mid-Term presentation, held at Eurospace on November 25, 1991. 2 Driving Parameters. They are: High energy density power source to save mass for the main experiment. Experiment to be probably with Laser transmission, leading to approx. 1KW electrical consumption. Demonstrator has to be simple, robust and inexpensive. Use of on the shelf equipment where practicable. Opportunity to flight could be 1995. Several launchers still in competition, but shuttle GAS no more considered. 3 General considerations on use of High Energy Density Power Sources. Traditional electrical power sources, i.e. Ni-Cd, Ag-Zn, Ni-H?, giving up to 100 Wh/kg energy density, could be used whatever will be the type of platform or launcher finally selected to carry on the experiment. These sources have a long history in space use and could be accommodated in any size and arrangement to fly in any conditions. As the purpose of Powersat demonstrator is, at a minimum cost, to verify the concept of transmitting power through space, it is intended to reduce the mass
