The invention provides a testing platform for position and attitude precision of a dual-antenna receiver and a testing method thereof. The testing platform comprises a supporting device, a linear guide rail and a traction system. The supporting device consists of a lifting support and a rotation support. The linear guide rail includes a U-shaped-groove guide rail with an upward opening, a sliding block, and a planar slipway, wherein the sliding block and the planar slipway are arranged above the U-shaped-groove guide rail; the U-shaped-groove guide rail is installed on a support platform; and two antennas are installed on the slipway. The traction system includes a speed regulating motor, a driving wheel, a gear belt, limit switches and a fixedly connection device; the speed regulating motor and the driving wheel are fixed on steel guard bar tubes at the two sides of the linear guide rail by the fixedly connection device; the gear belt is connected with the speed regulating motor and the driving wheel; one side of the gear belt is connected with the slipway fixedly; and the limit switches are arranged at the two ends of the linear guide rail. Therefore, the position and attitude precision of the dual-antenna receiver under different base line lengths and different speeds can be tested; and a problem of difficult positioning and attitude measuring precision evaluation of the dual-antenna receiver can be solved.
Description
technical field [0001] The invention relates to the technical field of positioning and attitude measurement of a dual-antenna (GNSS) receiver for agricultural machinery, in particular to a testing platform and a testing method for the position and attitude accuracy of a dual-antenna receiver. Background technique [0002] Automatic navigation of agricultural machinery is a core key technology in the precision agricultural technology system, which is widely used in agricultural production processes such as farming, sowing, fertilizing, spraying, and harvesting. Position and attitude information are important parameters in the automatic navigation control of agricultural machinery, and it is of great significance to study the accuracy of positioning and attitude measurement for agricultural machinery navigation control. [0003] At present, there are two common agricultural machinery positioning methods. One is relative position measurement, that is, the relative position meas...
