GNSS receivers (Global Navigation Satellite System receivers) are precision instruments used to determine geographic location by receiving signals from multiple satellite systems such as GPS (USA), GLONASS (Russia), Galileo (EU), and BeiDou (China). These receivers are essential in land surveying, construction, mapping, agriculture, and geospatial applications where high accuracy is required.
Total stations are advanced surveying instruments that combine an electronic theodolite (for measuring angles), an electronic distance meter (EDM), and a microprocessor with data storage and display. They are essential tools for land surveying, construction, and engineering projects where precise measurements of distances, angles, and coordinates are required.
A survey drone is an unmanned aerial vehicle (UAV) equipped with cameras, GNSS receivers, and sometimes LiDAR or multispectral sensors, used to capture high-resolution aerial data for mapping, surveying, and inspection purposes. These drones offer fast, cost-effective, and accurate alternatives to traditional land surveying, especially over large or hard-to-reach areas.
