Аннотация

The purpose of this study is to analyze the stage of development of the geodetic network in Tashkent city, conduct satellite observations, and preprocess measurements to establish a urban frame network. The stages of development of the geodetic network in Tashkent were analyzed and evaluated. A preliminary reconnaissance was conducted at the work site to verify the suitability of selected points for satellite observations. Suitable days for field measurements were scheduled using software. Observations were carried out at 9 points of the designed frame network using 6 Chcnav i90 GNSS receivers in 2 sessions employing the Static method. The sessions were linked by 3 points, and each session lasted four hours. Measurement data from the Chcnav i90 GNSS receivers were obtained in ‘RINEX’ format for processing. Joint measurements from the two sessions were processed using Trimble Business Center software version 5.52. Initial adjustments were made to the measurements of the lengths between points, and their accuracy was verified. The maximum root mean square error of side measurements was found to be less than the specified value for the frame network. A figure closure program was utilized to accurately determine baseline length errors.
