Evaluation of the accuracy of the new Primary Precise Geodetic Network in Korea
Accuracy of the Primary Precise Geodetic Network (PPGN) established during the period of 1975–1994 in Korea is investigated through an analysis of residual from free network adjustment. The PPGN, composed of 1155 points with mean side-length of 11 km, was surveyed by EDM trilateration to revise old...

The PPGN, composed of 1155 points with mean side-length of 11 km, was surveyed by EDM trilateration to revise old triangulation network established in 1910 s. A-posteriori standard deviation of unit weight is 3.8 × 10−6 of the observed length. Most of the estimated error ellipses of horizontal coordinates are nearly circular with a radius |
