Abstract
Description
당 기술 분야에서 이들 및 다른 문제점들을 극복하는 본 발명은, 일 관점에서 안정한 기본 레퍼런스가 디바이스의 통신측을 구동하도록 사용되는 기본선 주파수 레퍼런스로부터 GPS 목적들을 위해 유도될 수 있는 조합된 통신/위치 확인 시스템에서의 주파수 관리를 위한 시스템 및 방법에 관한 것이다. 이 기본선 레퍼런스는 실시예들에서, 예를 들면, 소프트웨어 온도 보정, 하드웨어 온도 보정, 제조 시의 주파수 바이어스(bias)의 측정, 자동 주파수 제어(AFC) 또는 디바이스의 통신 부분에서의 정확도를 확립하기 위한 다른 기술들과 같은 직접 보정 없이 동작할 수도 있다. GPS 수신기 부품은 따라서 합성기(synthesizer) 또는 다른 소자(element)에 일체화된 중간 발진기를 사용하여 기본선 레퍼런스를 수신하고 이 기본을 GPS 주파수들에 상향 변환할 수도 있다. 따라서, 디바이스의 위치 확인부를 위한 주파수 레퍼런스는 또한 원래의 통신(기본선) 클록과 동일한 범위의 주파수 편차를 나타낼 수 있다. 그러나, 본 발명의 실시예들에 따르면, 디바이스의 통신부와 통신하는 프로세서 소자가 셀룰러 베이스 또는 다른 팩터들로부터의 편차에 기초하여 주파수 드리프트(drift)를 트래킹할 수도 있다. 이 프로세서 또는 다른 논리 소자는 따라서 디바이스의 위치 확인부에 도플러 검색 또는 다른 논리 디지털 메시지를 통신하여, 원래의 통신 주파수 레퍼런스의 편차를 지시할 수도 있다. 이 논리 디지털 메시지는 실험적 데이터 및 연관 알고리즘들과 함께 시스템의 열역학적 특성들로부터 유도될 수도 있는 주파수 드리프트율과 같은 예측 주파수 정보를 포함할 수도 있다. 위치 확인 수신기는 그후 더 빠르고, 더 낮은 신호 강도들에 민감하며, 더 양호한 위치 정확도를 갖도록 위치 수집 및 트래킹 처리를 구동하기 위해 중심 주파수 또는 도플러 검색 윈도우의 폭, 주파수 스캔율, 또는 다른 검색 파라미터들을 조정할 수도 있다. 따라서, 조합된 디바이스의 GPS 또는 다른 위치 확인부는 그 자신의 국부 발진기를 포함할 필요가 없고, 여전히 비교적 적은 비용으로 충분한 GPS 성능을 달성한다.
