摘要：
A digital and an analog phase-locked loop receiver were operated in parallel, each tracking the residual carrier from a spacecraft. In this way, two separate Doppler measurements were obtained for one observation window. The two receivers agreed on the magnitude of the Doppler effect to within 1 mHz. There was less jitter on the data from the digital receiver, and this was due to its smaller noise bandwidth.
