Computer feedback and control, and frequency stability featured prominently as factors in the precision of its tracking.

	STADAN’s two [[Range and Range Rate\|RARR]] systems were examples of the continuous wave (CW) ranging process. Both used ranging tones; upgraded to digital coding for the S-band system in later years. A feature of CW systems is calculating spacecraft velocity from the frequency shift between the uplink and downlink signals; commonly known as the Doppler effect - the ‘eeeee-aaaaah’ engine sound you would hear as a racing car comes towards you standing at the side of the track, and as it goes past you and off into the distance - a change from a high tone to a lower one. Sub-carriers also provided telemetry and command facilities.		STADAN’s two [[Range and Range Rate\|RARR]] systems were examples of the continuous wave (CW) ranging process.
