The swift advancement of sensor fusion methodologies in global navigation satellite systems (GNSSs) and inertial measurement units (IMUs) presents a significant prospect to enhance the practicality, efficiency, and user experience of very precise real time kinematic (RTK) GNSS positions. Now that Topcon Integrated Levelling Technology (TILT) compensation technology is available, GNSS RTK can be used more effectively and adaptably in scenarios with greater constraints by automatically adjusting pole tilt from plumb. However, most conventional tilt compensation methods need laborious on-site calibrations and are vulnerable to magnetic disturbances. In addition, it is common for the tilt correction range to be 15 degrees. This research, instead, looks at the precision and repeatability that the RTK GNSS was able to achieve on 20 December 2023, using various satellite configurations. The United States' National Standard for Spatial Data Accuracy (NSSDA) governs how spatial data accuracy is reported. At 15-degree tilt angles, where a three dimensional positioning precision of approximately 1-15 cm that is possible in our investigation, the receiver IMU-based tilt correction is appropriate.
