Journal of Sensors, Volume 2021, Issue 1, 2021., 2021 Due to the short peak observation time of global navigation satellite systems (GNSS), the accuracy of the tropospheric delay estimation and the positioning are poor. In this study, a rapid GNSS network solution for mountainous regions is presented. The high‐precision tropospheric delay at ground points is obtained from long‐term ground observation data
