Description

Technical Field

[0001] The utility model relates to the technical field of engineering surveying equipment, in particular to a device for increasing the signal coverage of an RTK base station. Background Art

[0002] RTK (Real-time kinematic) is a new and commonly used satellite positioning measurement method that can obtain centimeter-level positioning accuracy in real time in the field. It plays an important role in engineering stakeout, topographic mapping, and various control measurements, greatly improving work efficiency.

[0003] When using RTK for field measurement, it is necessary to select a location with a wide field of view and high terrain near the operation area to set up a base station to provide operation signals for the mobile station. In addition, there should be no strong electromagnetic interference within a range of about 200m around the measurement station, such as TV towers, microwave stations, high-voltage transmission lines, etc.

[0004] When the operating range is large and the RTK base station cannot fully cover it, it is necessary to relocate the base station according to the actual situation, select a suitable location to re-install the instrument, and restart the base station calibration.

[0005] RTK measurement technology relies on the signal emitted by the base station, and the signal strength needs to meet the accuracy of the mobile station to measure accurate positioning data. In actual measurement operations, the signal quality is often reduced due to the obstruction of ground obstacles (such as steep slopes, buildings, trees, etc.) between the base station and the mobile station, resulting in poor RTK measurement data accuracy.
