Problems solved by technology
[0003] When the RTK system measures a large area, it is necessary to manually measure the height difference between the RTK device and the ground, and then process the coordinate information and the height difference calculated by the RTK system to obtain the actual position information on the ground. The efficiency of such a system or measurement method Low, requiring a lot of manpower, especially when measuring sandy beaches, soft mud and other grounds, because the bottom of the measuring rod cannot be fixed, resulting in a serious decrease in measurement accuracy

The invention relates to a self-stabilization distance measurement assisted RTK data acquisition system and a measurement method thereof. The system comprises an RTK measuring unit, a stabilizing unit, a distance measuring unit and a data processing unit. The stabilizing unit comprises a fixed assembly and a movable assembly. The distance measuring unit is fixedly connected to the lower side of the RTK measuring unit; the RTK measuring unit and the distance measuring unit are fixedly connected to the movable assembly and move along with the movable assembly; and the movable assembly is used for adjusting the connecting line between the RTK measuring unit and the distance measuring unit to be perpendicular to the horizontal plane. The data processing unit is in communication connection with the RTK measuring unit and the distance measuring unit, and the data processing unit stores distance information between the RTK measuring unit and the distance measuring unit. Manual complicated measurement rod fixing, ground distance information measurement and the like are not needed, and the method has the characteristics of high efficiency, automatic completion and the like.
Description
technical field [0001] The invention relates to the field of RTK measurement, and specifically refers to an RTK data acquisition system assisted by self-stabilizing ranging. Background technique [0002] Carrier phase difference technology (Real time kinematic, referred to as RTK) is a difference method for real-time processing of carrier phase observations of two measurement stations. The carrier phase collected by the reference station is sent to the user receiver for difference calculation and coordinates. With the continuous development of RTK technology, the application of RTK antenna is more and more extensive. [0003] When the RTK system measures a large area, it is necessary to manually measure the height difference between the RTK device and the ground, and then process the coordinate information and height difference calculated by the RTK system to obtain the actual position information on the ground. The efficiency of such a system or measurement method Low, it ...
