Abstract:
The patent describes a control circuit having a digital memory for providing sweep voltages to receivers in a doppler satellite tracking station of proper amplitude and duration to ensure searching in the correct doppler frequency range. An internally generated ramp function voltage is combined with a reference voltage to produce a composite sweep signal for the receiver. The reference voltage level is determined either from a set of digi-switches or from digital memory circuit which outputs a digital signal that is a function of the frequency of a received doppler signal.
