1. Positioning accuracy: High-precision GPS measurement equipment can provide high positioning accuracy, usually in the range of a few millimeters to a few centimeters. It uses signals from multiple satellite positioning systems such as GPS, GLONASS, Galileo, etc. to achieve accurate location measurements2. Real-time differential correction: High-precision GPS measurement equipment is usually used in conjunction with a real-time differential correction system. By receiving correction data from reference stations, it can reduce the influence of factors such as signal propagation delay and atmospheric delay, and improve measurement accuracy.3. Data collection and recording: High-precision GPS measuring equipment has data collection and recording functions. It can record measurement data, location coordinates and other relevant information for subsequent data processing and analysis4. Environmental adaptability: High-precision GPS measurement equipment usually has good environmental adaptability and can operate stably under various climatic conditions. They are waterproof, dustproof and durable for outdoor use5. Scope of application: High-precision GPS measuring equipment is widely used in surveying fields, including land surveying, engineering surveying, building surveying, agricultural surveying, etc. They can be used to measure topography, land boundaries, building structures, roads, and water resources, providing accurate geographic information for various engineering and planning projectsThe accuracy, real-time and flexibility of high-precision GPS measurement equipment make it an indispensable tool in the field of modern measurement. They provide accurate, efficient, and reliable geographic measurement solutions and are widely used in various industries and fields.
