Satellite-to-Satellite Data Transfer and Control.
7th Communications Satellite Systems Conference, 1977Abstract : The LES-8 and -9 satellites are three-axis stabilized earth-orbit spacecraft which provide communications at UHF and K-band frequencies with the capability of simultaneously establishing and automatically maintaining a K-band (36-38 GHz) satellite-to-satellite data link. The inter-satellite data crosslink extends the earth coverage over that
