We determined three dimensional precise WGS 84 coordinates if two points in Bohyunsan Optical Astronomy using the GPS. One if the two points is the center on the top of pier for 1.8m telescope, and the other one is placed on the hill beside the dome of 1.8m telescope. We performed the simultaneous GPS observation at the KAO GPS station and Bohyunsan Observatory for 5 days from December 18 to 22, 1993. We employed three Trimble 4000SST receivers for these observations. The observed data were processed by TRIMVEC-PLUS software of Trimble with the MBPS method and the Triple Difference L1/L2 ION free technique. Through this research, we determined WGS 84 latitude, longitude and height of 1.8m telescope in Bohyunsan Optical Astronomy Observatory with the values of 36'9 53."1943N ± 0.d0018, 128'58 35."6829E ± 0."0029, 1162.47m ± 0.04m, respectively.
