GNSS positioning and measurement technology plays a crucial role in modern engineering, especially in key operations such as control network construction and displacement monitoring. This technology is based on the Global Navigation Satellite System (GNSS), and its core workflow is to efficiently collect satellite signals by reasonably arranging two or more GNSS receivers. These receivers, with advanced RF technology and signal processing algorithms, are able to stably and accurately capture signals from multiple satellites

After the collection is completed, technicians use professional measurement data processing software to conduct in-depth analysis and processing of the satellite data obtained. These software typically integrate precise solution models, including carrier phase difference (RTK), real-time dynamic positioning (PPP), and other technologies, which can effectively eliminate various error sources and accurately calculate the three-dimensional coordinates of control points, providing high-precision spatial benchmarks for engineering construction.
GNSS positioning measurement technology has a series of outstanding performance characteristics:

Millimeter level ultra-high precision: By using advanced carrier phase measurement technology and combining with multi satellite system fusion algorithms, it can achieve a positioning accuracy of up to 1mm, ensuring the ultimate accuracy of engineering measurement data.

Super strong climate adaptability: It is not restricted by severe weather conditions. It can stably receive satellite signals and maintain high-precision positioning in extreme weather environments such as rainstorm, sand and dust, or dense fog, so as to ensure the continuity of engineering survey work.

No visibility restrictions: Breaking through the bottleneck of traditional measurement methods where observation points must have visibility, even in areas with complex terrain and numerous obstacles, flexible measurement operations can be carried out, greatly expanding the scope of application of measurement work..

Fast observation and efficient operation: With the ability to quickly collect data, it can complete a large number of observation tasks in a short period of time. Combined with real-time data processing technology, it significantly improves work efficiency and greatly shortens the engineering measurement cycle.
