4 Overview

The Global Navigation Satellite System (GNSS) dynamic area measuring instrument is a real-time measurement system that uses the Global Navigation Satellite System (GNSS): Degree, latitude, elevation and other data information are used to obtain the coordinates of key points on the boundary of the measured area, and then calculated using mathematical methods: Electronic measuring instruments for distance, mileage, area and other data: Mainly includes GNSS antenna, GNSS positioning module, display Display screen (touch keyboard), microprocessor, data memory, etc:, its structure is shown in Figure 1: Figure 1 Basic structure of GNSS dynamic area measuring instrument
