Abstract

PURPOSE:To obtain the accurate delay time in a simple way by receiving and demodulating at the central station the test signal radiated from the satellite station in the form of the electromagnetic wave to be compared with the test signal at the central station with regard to the phase and thus measuring the delay time of the wired circuit. CONSTITUTION:The data is transmitted to satellite station 2 from the signal transmission part of central station 1 via the wired circuit and then radiated as the electromagnetic wave. In this case, the test signal is transmitted to station 2 from station 2 from station 1 via the wired circuit, and the test signal radiated from station 2 as the electromagnetic is received and modulated at station 1 to give phase comparison 29 to the test signal at station 1. And then the delay time is measured for the wired circuit, thus obtaining the accurate delay time in a simple way.
