China’s field work for new measurements of Mount Everest — the world’s, highest peak — are now complete. However, it will take two to three months for scientists to calculate and release its exact height, according to CHC Navigation, whose GNSS receiver was used.

The eight-member Chinese survey team reached the summit on May 27. The team erected a survey marker and installed a GNSS antenna on the snow-covered peak. The team also conducted a GNSS survey, snow depth measurement and gravity survey, said China’s Ministry of Natural Resources.

Scientists will use multiple traditional and modern measurement techniques to perform comprehensive calculations of the measurement data. After data analysis and processing, they will carry out theoretical studies and repeated verifications to determine the accurate height. Complex calculations are needed to eliminate errors caused by factors such as temperature, air pressure and the refractive environment.
