Title: Azimuth search method
Inventor: KITAGAWA OSAMU
IPC: H01Q3/02
Filed: 1998-05-15
Abstract: PROBLEM TO BE SOLVED: To provide a receiver by which an initial acquisition can be finished in a shorter time than before. SOLUTION: In order to acquire a satellite just after makeup of a power source or the like, a last channel search program 400, an adjacent channel search program 402 and a total channel search program 404 are executed successively. The last channel search program 400 is a program by which the satellite is acquired by setting an oscillation frequency of a built-in synthesizer based on the information stored at the time of power source disconnection, and usually acquisition of the satellite succeeds in this step. In the case that the satellite acquisition by the last channel search program 400 resulted in failure (406), the adjacent channel search program 402, which is a search relative to two satellites adjacent to the satellite acquired before the power source disconnection, is executed.  In the case that the satellite acquisition by the adjacent channel search program 402 resulted in failure (408), the total channel search program 404, which is a search performed for all satellites, is executed for the first time.
