Description

인공위성에 의한 측위방법
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 GPS시스템의 측위원리의 표시도.
제2도는 위성배치와 측위결과의 오차발생과의 관계도.
제3도는 오차방향을 구하는 플로챠트.

Claims (4)

  1. 위성으로부터의 위성궤도에 관한 정보를 수신하여 자기의 위치를 결정하는 방법에 있어서 이용하는 위성의 위치로부터 오차가 생기는 방향을 연산하여 그 오차방향에 대하여 도로지도정보를 이용하여 자기의 위치를 결정하도록 한것을 특징으로하는 인공위성에 의한 축위방법.
  2. 위성으로부터의 위성궤도에 관한 정보와 시각에 관한 정보를 수신하여 자기의 위치를 결정하는 방법에 있어서 이용하는 위성의 1조 조합에 의하여 1개의 오차가 발생하는 방향을 연산하여 이용하는 위성의 다른 조합에 의하여 다른 오차가 생기는 방향을 연산하여 이들의 오차가 생기는 방향의 교차점에 의하여 자기의 위치를 결정하는 인공위성에 의한 측위 방법.
  3. 제1항에 있어서 측위연산의 결과가 지도의 적절한 위치인가 아닌가를 판단하여 적절한 위치가 아닌 경우에는 위성의 배치로부터 오차방향을 계산하여 상기 측위연산위치와 오차방향으로 그려지는 직선상에서 더우기 적절한 위치를 구하여 그 위치를 자기 위치로 하는 인공위성에 의한 측위방법.
  4. 위성으로부터의 궤도에 관한 정보와 시각에 관한 정보를 수신하여 자기의 위치를 연산에 기초로하여 결정하는 방법에 있어서 위성으로부터의 정보에 기초하여 자기의 위치를 연산하는 스텝(200)과 자기 위치가 지도의 도로상에 있는지 어떤지를 판단하는 스텝(201)과 자기위치가 도로상에 있을경우 위성의 배치로부터 오차방향 θ를계산하는 스텝(100)과 상기 자기 위치를 통과하여 상기 오차방향 θ의 경향의 직선을 그리는 스텝(202)와 전회 및 전전회의 위치를 통과하는 직선과 상기 직선과의 교차점을 구하는 스텝(204)과 상기 교차점에 가장 가까운 도로상의 점을 자기 위치로 하여 출력하는 스텝(205), (206)에 의하여 성립되는 인공 위성에 의한 측위방법.
