Members of a Chinese surveying team reached the summit of Mt. Qomolangma in the morning of 27 May 2020 via the northern Tibetan route, a crucial step in the country's mission to remeasure the height of the world's highest peak. After reaching the summit, the expedition team erected a survey marker and installed a GNSS antenna.
The surveyors used a global navigation satellite system receiver, a gravimeter, snow-depth radar and a meteorological measuring instrument to determine the height of Qomolangma. Innovations applied in the latest survey include the application of the BeiDou-3 Navigation Satellite System, domestic surveying equipment, the airborne gravimeter and 3D interactive virtual reality. It will probably take two to three months for scientists to calculate and release the exact height of Mount Qomolangma.
According to the Joint Statement Between the China and Nepal published on 13 October 2019, both countries will jointly announce the height and conduct scientific researches. The Nepali government's efforts to measure the height of Mt. Qomolangma come amid speculations from some scientists that the world's tallest mountain has shrunk after the devastating earthquake in 2015 in Nepal.
