Abstract :
An L1 band (1575.42 MHz), C/A (coarse/acquisition) code GPS receiver for precise time comparisons has been developed. GPS measurements in common-view have been carried out between the Korea Standards Research Institute (KSRI) and the Communications Research Laboratory (CRL), Japan. The frequency stability of the KSRI master clock has been measured against the master clock of CRL for 50 d. The frequency stability is about 1 part in 10/sup 13/ for the averaging time of 4 d.<>
