Aiming to measure the mountain's exact altitude above sea level, an eight-member Chinese research team has reached the summit of Mount Everest to erect on the summit a survey marker and install a GNSS antenna (global satellite positioning).
Complex calculations are needed to eliminate errors caused by factors such as temperature, air pressure, and refractive environment.
GNSS
After data analysis and processing, they will carry out theoretical studies and repeated verifications to determine the exact height, a job that will last two to three months.
China has carried out six major measurements on the mountain since the establishment of the People's Republic in 1949. The height recorded in 1975 was 8,848.13 meters while in 2005 it reached 8,844.43 meters..
If you ask us what is the highest mountain on Earth, everything will depend on where we start measuring. If you ask us which one is the furthest from the center of the Earth, then we must start forgetting such familiar names. like Everest or even Mauna Kea. Because that title is held by Mount Chimborazo, in Ecuador, which surpasses both measured from the Earth's core.
