Dahewan Demonstration Area Positioning Terminal Test Data - 202208-09

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.
