Core Viewpoint - The article commemorates the 50th anniversary of China's first independent measurement of Mount Everest's height, highlighting the significance of accurate height measurement for international standards and environmental monitoring [1][3]. Measurement Process - The precise determination of Mount Everest's height aims to resolve the inconsistencies in international height data, providing essential information for glacier monitoring and ecological studies [3]. - The 2020 measurement utilized a global elevation benchmark agreed upon by China and Nepal, incorporating gravity measurements and advanced satellite data to create a high-precision gravity field model of the Everest region [3][5]. - The measurement involved a team of climbers establishing a benchmark at the summit, with simultaneous triangulation and intersection measurements conducted from six reference points at the mountain's base [4]. Technology and Equipment - The climbers employed Beidou satellite navigation signals for accurate positioning and used ice and snow radar to measure the thickness of the snow layer at the summit [5]. - The measurement process required human presence due to the extreme conditions at the summit, which rendered helicopters and drones ineffective for stable operation [8][11]. Climatic Conditions - The measurements have historically been conducted in May, as this month offers a brief window of relatively stable weather conditions, avoiding the harsh winds and precipitation typical of other months [12][13]. - The peak's summit area is limited in size, making helicopter landings impractical, and the measurement equipment necessitates direct human operation to ensure accuracy [11][14].
