Abstract

PURPOSE:To collect a monitor data in a short time by predetermining a reference polling signal from a central monitor satellite ground station and a monitor timing of each monitored satellite ground station with respect to the reference polling signal. CONSTITUTION:Each of monitored satellite ground stations 2a-2c sends sequentially a monitor signal and when a central monitor satellite ground station 1 receives a monitor signal 7c from the final monitored satellite ground station 2c, the central monitor satellite ground station 1 sends a reference polling signal 6 of a succeeding monitor period again. The monitor signal is sequentially returned from each of the monitored satellite ground stations 2a-2c to the central monitor satellite ground station l sending the reference polling signal 6 and the central monitor satellite ground station 1 collects a data from each of the monitored satellite ground stations 2a-2c. In this case, the timing of the monitor signal of each of the monitored satellite ground stations 2a-2c is predetermined. Thus, the monitor data are collected in a short time.

A reference polling signal 6, which serves as a timing reference, is sent to each monitored satellite ground station 2a to 2C using the reference slot, and the monitored satellite ground stations 2a to 2c that have received the reference polling signal 6 transmit the reference polling signal. The number of received slots is counted based on the number of slots received, and when the slot is in the order assigned in advance to itself, a monitoring signal is sent back to the central monitoring satellite ground station 1. That is, the monitored satellite ground station 2a sends the monitoring signal 7a to the -th slot counting from the reference polling signal 6, and the monitored satellite ground station 2b sends the monitoring signal to the second slot counting from the reference hauling signal 6. Send 7b. In this way, each monitored satellite ground station sends a monitoring signal in sequence, and when the central monitoring satellite ground station 1 receives the monitoring signal 7c from the last monitored satellite ground station 2c, it sends the reference polling signal again for the next monitoring cycle.
