Satellite was equipped so that accurate measurement of mini-track beacon frequency (with Doppler component removed) was sufficient to determine internal temperature; sensitive receiving system utilizing highly stable but tunable first local oscillator and noise-eliminating tracking filter, was developed; other information such as roll rate and rocket performance was also obtained.
