Abstract
The invention reveals a global position system (GPS) antenna system of multiple antenna selection usage. The system is used in a GPS navigator. The GPS antenna system comprises: at least two antennas, which are respectively arranged on two adjacent sides of the GPS navigator; a gravity sensor, which is used to acquire analogue data of GPS navigator space position transformation through sensing; an analog-to-digital converter, which is connected with the gravity sensor so as to convert the analogue data of the GPS navigator space position transformation sensed by the gravity sensor to digital data; a antenna selection parallel table, which records a corresponding selection relation between the digital data of the space position transformation and the antenna; a processing module, which is connected with the analog-to-digital converter, is used to call the antenna selection parallel table, acquire the selected antenna according to the digital data of the space position transformation and let the selected antenna start. By using the GPS antenna system, the GPS navigator, which changes different display directions, can receive signals very well.
Description
[technical field]
The invention provides a kind of gps antenna system, refer to the gps antenna system that a kind of many days line options are used especially.
