摘      要：Determining the altitude of mountains is one of the most fundamental challenges for ***,the main objective of the study is to determine the altitudes of the three main summits in Ecuador through GNSS positioning,referring to the official vertical datum of Ecuador and the geo-potential surface(W_(o)).The three peaks are active volcanoes named Chimborazo,Cotopaxi and Cayambe,all of which are known to be over 5700 m above sea *** GNSS was performed on the summit of the volcanoes,and the GPS leveling method was applied on nearby *** these summits,the correction of the potential difference between the mean sea level and W_(o) was *** altitudes referred to the mean sea level were compared with other registered heights,and the results are more accurate than previous geodetic missions.
