Abstract : The performance of a Rapid Carrier Acquisition circuit for low data rate satellite communications equipment is described. The results achieved for carrier acquisition at signal to noise ratios of 30 dBHz show that acquisition can be achieved in 300 milliseconds, giving two orders of magnitude improvement over currently implemented equipment. Details of performance with various modulation schemes and operation at signal to noise ratios as low as 25 dBHz are given.
