Apparatus and method for receiving of GPS signal

The invention of the GPS-signal receiver apparatus, and relates to the method, the first type antenna and each GPS antenna section, the first type antenna and a plurality of second-type antenna comprising a plurality of second type antenna having different directionality either selecting the selected GPS signal connecting unit, and the first type of antenna and analyzes the plurality of the GPS signals received from any one of antennas selected one of the two types of antenna, for detecting a jamming signal contained in the GPS signal including a jamming signal detection unit, the GPS signal selection unit when a jamming signal is detected from the GPS signal sequentially connected to a plurality of second type antenna, the jamming signal detecting section from the second type of antenna in the order associated with the selected GPS signal unit by measuring the strength of the jamming signal contained in the received GPS signal, the intensity is the weakest of the second type do not jamming signals of a plurality of a second type antenna And controls so that the antenna with the final connection.
