2026-09-18 Dahewan Demonstration Area Positioning Terminal Test Data - 202208-09 doi:10.57760/sciencedb.iga.01192 en To evaluate and compare the positioning performance of different terminals, a specialized test was conducted in the Dahewan Demonstration Area from August 31 to September 2, 2022. Data collection was carried out simultaneously using a self-developed high-precision positioning terminal and a commercial Qianxun A20 board. The generated dataset comprises four independent tests, totaling 18 data files with a combined size of 635 MB, recording three days of raw observation data. The data is stored in the universal RTCM3 standard format with a sampling rate of 1 second, fully covering multi-frequency, multi-satellite system observations, providing a foundation for subsequent accuracy analysis.
