A Study on the Improvement of Accuracy in Plane Positioning by Trilateration

삼변측량에 의한 수평위치 결정의 정확도 향상에 관한 연구

In this paper a two dimensional network adjustment theory is developed to analyze the plane trilateration network of single triangle network, of quadrilateral network, of polygon trilateration network and of combined network. The characteristics of error were analysed by developing an error propagation equation for each form of plane trilateration network. In case of combined network, the result of error analysis was represented by error ellipses and gross error detection was carried out by data snooping method.

본 논문은 2차원망조정이론을 정립하여 단열삼각망, 사변삼각망, 유심삼각망과 복합측지망의 각 평면 삼변망을 해석하였다. 이들 수평삼변망의 형태에 따른 오차전파식을 유도하여 오차특성을 해석하였고, 또한 복합측지망에서는 오차해석 결과를 오차타원으로 나타내었으며, Data Snooping 방법에 따른 과대오차검출을 시도하였다.
