摘要：
An absolute calibration of V-band crosslink transmitting channel for inter-satellite communication is addressed. The satellite crosslink signal is band-sampled along with the pulse per second (1PPS) generated by satellite time keeping system. The sampling data of the crosslink signal is down-converted to intermediate frequency carried signal and then the high rate data stream is converted into several low rate data streams with a serial-to-parallel transformer. Acquisition is done for each low rate data streams. With sampling data of PPS, the absolute delay of crosslink signal transmitting channel can be calculated. The simulated result indicates the precision of the calibrated algorithm is main dominated by the sampling frequency.
