Abstract

본 발명은 무선 호출기의 GPS 수신장치에 관한 것으로 무선 호출기의 무선호출신호 수신기능은 물론 GPS 신호 까지도 수신하도록 한 것이다.The present invention relates to a GPS receiver of a wireless pager, and to receive a GPS signal as well as a wireless call signal reception function of the wireless pager.

이와 같은 본 발명은 안테나를 통해 수신된 무선 호출신호 및 GPS 신호를 검출하여 각 신호에 맞는 발진 주파수를 혼합하여 해당 신호를 출력하는 무선 수신 수단과, 상기 무선 수신부에서 얻어진 GPS 데이타 중간 주파수와 무선 호출 신호의 중간 주파수에서 데이타를 분리한 신호처리수단에서 얻어진 데이타를 식별하여 출력수단을 통해 사용자에게 전달하도록 제어신호를 출력하는 제어수단으로 구성한다.The present invention detects the radio call signal and the GPS signal received through the antenna and the radio receiving means for mixing the oscillation frequency suitable for each signal to output the corresponding signal, the GPS data intermediate frequency obtained from the radio receiver and radio call And a control means for identifying the data obtained from the signal processing means that separates the data at the intermediate frequency of the signal and outputting the control signal to the user through the output means.
