Four experimental satellites developed by M.I.T. Lincoln Laboratory were launched during 1965; built to test advanced communications devices and techniques, three of four satellites are working satisfactorily even though only one was injected into its planned orbit; first all solid-state transponders were used to generate RF power at X band; two antenna pointing systems using inputs from sensors operating at "visible" wavelengths worked properly within limitations of incorrect orbits; voice and data were transmitted through satellites successfully; magnetic torquing of spin axes was used to align satellites normal to sun line.
