일본 및 기타 여러 국가에서는 긴급 전화를 걸려면 자동 위치 식별이 필요합니다. 하지만 GPS(Global Positioning System) 신호가 극도로 약한 곳에서는 신뢰할 수 있는 위치를 신속하게 제공하는 것이 문제가 된다. 우리는 타이밍 동기화 모바일 네트워크를 기반으로 하는 보조 GPS(AGPS) 아키텍처를 위한 획득 방식을 제안합니다. 시스템 오류, 코드 불확실성 범위 및 주파수 불확실성 범위에 대해 설명합니다. 이 방법을 사용하면 획득 검색 범위가 크게 줄어들고 장기간 일관된 상관 관계가 가능해집니다. 시뮬레이션과 실험을 통해 이 방법이 사용자 핸드셋에 대해 빠르고 효율적이며 절전 효과가 있음이 입증되었습니다. 또한 AGPS 수신기는 핸드셋에 천체력이 없어도 짧은 TTFF(Time To First Fix) 시작을 수행할 수 있습니다.

Abstract: Automatic location identification is required for emergency calls in Japan and many other countries. However, promptly providing a reliable position is a problem in places where the global positioning system (GPS) signal is extremely weak. We propose an acquisition scheme for the assisted GPS (AGPS) architecture based on a timing-synchronized mobile network. System errors as well as code uncertainty range and frequency uncertainty range are discussed. With this method, the acquisition search range is significantly reduced, and a long-time coherent correlation is made possible. Simulations and experiments prove that the method is fast, efficient and power-saving for the user handset. Furthermore, the AGPS receiver can perform a short TTFF (Time To First Fix) start even with no ephemeris kept in the handset.
