The Lincoln Laboratory Satellite Communications Program is concerned with the development and testing of new spacecraft and ground terminal techniques. The spacecraft development program attempts to maximize satellite effective radiated power per unit mass by research on improved spacecraft power-generation systems, spacecraft transponder techniques, high-efficiency spacecraft transmitters, the development of high-gain spacecraft antennas and the associated spacecraft attitude stabilization which is required by such antennas. The surface terminal development program principally involves communication signalling techniques including the development of modulation-demodulation systems which are considerably more efficient than those used for conventional satellite communications. In addition, there is a heavy emphasis on the development of multiple-access signalling techniques which permit the simultaneous use of a satellite by tens or hundreds of users without the necessity of elaborate central synchronization control systems. The spacecraft and surface terminal techniques are tested in a series of Lincoln Experimental Satellites (LES) and Lincoln Experimental Terminals (LET). (Author)
