TOA기법과 TDOA기법의 위치 오차 특성 및 DOP 비교

Comparisons of Position Error Characteristics and DOP Between TOA and TDOA Technique

This paper presents a relationship between DOP for TOA and TDOA is defined using the error covariance matrix of TDOA. It is analytically shown that the error ellipsoid of TOA is as same as that of TDOA in magnitude and in orientation, which means that DOP for TOA is identical to the DOP for TDOA. By computer simulation, the positioning performance of two methods is compared, and we verify our assertion.
