Discover how GNSS RTK technology revolutionizes surveying by providing superior positioning accuracy and operational efficiency.
Understanding the Basics of GNSS and RTK Technology
Global Navigation Satellite System (GNSS) and Real-Time Kinematic (RTK) technology are two pivotal components in the realm of high-precision surveying. GNSS encompasses various satellite constellations such as GPS, GLONASS, Galileo, and Beidou. These systems provide global coverage for geolocation and time synchronization.
RTK is a technique used to enhance the accuracy of GNSS positioning data. It achieves this by utilizing a fixed base station and a mobile receiver. The base station sends correction data to the receiver, which significantly reduces the errors caused by atmospheric conditions, satellite orbit deviations, and clock discrepancies. This correction process allows for centimeter-level accuracy, making it indispensable for surveying applications.
The Integration of GNSS and RTK for Enhanced Precision
Integrating GNSS with RTK technology brings about a transformative leap in positioning accuracy. This integration works by combining real-time satellite data with correction signals from the base station. The result is a highly accurate and reliable positioning system capable of achieving centimeter-level precision.
Spatix offers advanced solutions that seamlessly integrate GNSS and RTK technology. Their products, such as the SpatiX H7 SLAM and X5 Laser RTK, are designed to deliver unparalleled accuracy in various surveying environments. These devices support single-person operation, real-time 3D point cloud modeling, and non-contact measurement, even in GPS-denied and low-light conditions.
