Beschreibung
Zusammenfassung:	The present invention relates to a Loran-C (hereinafter referred to as Loran-C)/eLoran (hereinafter referred to as eLoran) multi-chain positioning apparatus for using ToA (signal arrival time) measurements, and to a method thereof. In particular, a raw ToA measurement value provided from a Loran-C/eLoran receiver is adjusted, uses a Brunavs model to compensate a pseudo distance error of the adjusted ToA measurement value, removes any time error and receiver clock offset using a simple equation, and then obtains a position of a signal receiving point using the ToA measurement value. 본 발명은 ToA(신호 도달 시간) 측정치를 이용하는 Loran-C(이하, 로란-씨라 함)/eLoran(이하, 이로란이라 함) 다중 체인 측위 장치 및 방법에 관한 것으로서, 특히 로란-씨/이로란 수신기에서 제공된 원시 ToA 측정치를 조절하고, 조절된 ToA 측정치의 의사거리 오차를 부르나브스 모델(Brunavs model)를 이용하여 보상하며, 임의의 시간 오차 및 수신기 시계 오프셋을 간단한 수학식을 이용하여 제거한 후, ToA 측정치를 이용하여 신호 수신 지점의 위치를 획득하는, ToA 측정치를 이용하는 로란-씨/이로란 다중 체인 측위 장치 및 방법에 관한 것이다.
