Abstract

In engineering and surveying, establishing a temporary bench mark (TBM) that have a reliable reduce level is extremely important since it contribute most of construction that is being done. This study is done to compare the heighting accuracy between total station and GPS with auto level serve as a reference. A total of 6 TBM is establish using fly leveling and these 6 TBM are re-observe using Total Station and GNSS levelling. Using the total station, the reduce level is transferred from reference point to all TBM using techeometry method. In GNSS leveling, a relative and absolute leveling method is used measure the orthometric height of each of the 6 TBM with fitted geoid as a reference surface. The values are compare with each other to reduce level (RL) that been establish using Auto level. The total station displays a wider range of errors from 0.13 m all the way to 0.004 m while the GNSS leveling gives a more consistence result from 0.011 m to 0.063 m. Thus, the total station give a more accurate result but low precision but that GNSS gives a high precision but lower accuracy
