Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of GPS receivers, in particular to a leveling bracket for distance measurement of a GPS receiver. Background Art
[0002] A leveling bracket is a device used to mount a GPS receiver. Its main function is to ensure that the GPS receiver is placed horizontally at the installation location. This is crucial in the distance measurement process because the GPS receiver needs to accurately receive signals from satellites to determine the location and calculate the distance by the time difference of the signals. If the receiver is not placed horizontally, it may cause unstable or inaccurate signal reception, thus affecting the accuracy of the distance measurement. In distance measurement applications, especially in scenarios that require high-precision measurements, such as geological exploration, land surveying, and construction surveying, it is common to use a leveling bracket. By ensuring that the GPS receiver is placed horizontally, errors caused by inaccurate posture can be minimized, thereby improving the accuracy and reliability of the measurement.
[0003] The height of the top of the existing leveling bracket can generally be adjusted, but the height adjustment mechanism generally needs to be manually stretched and then fixed by a fixing nut. The process is relatively laborious and the adjustment time is too long. In addition, the leveling angle of the leveling mechanism is limited and cannot achieve 360-degree infinite adjustment in the circumferential direction, which has certain limitations when used.
