Abstract

PURPOSE:To expand an acquisition range, to widen a search angle interval, and to shorten the time required for initial acquisition by lowering an alarm level set value at the time of the initial acquisition. CONSTITUTION:A scan is made from a scan start position 3 along a scan track 4 and a satellite is acquired at a satellite acquisition position 5. In this case, the alarm level set value at the time of the initial acquisition is set low, and the acquisition area 2 is set to theta1 larger than before. The interval of the scan track 4 is therefore widened and the time required to acquire the satellite is shortened.
