Abstract: The invention discloses a 2D dynamic calibrating table, for calibrating a GPS system arranged on a construction, comprising: a bearing frame, a moving platform, a double-layer two-way movement mechanism arranged between the bearing frame and moving platform to drive the moving platform to make 2D motion in two orthogonal directions, an electronic control system arranged on the bearing frame to control the driving action of the double-layer two-way movement mechanism, a GPS receiver arranged on the bearing frame, a computer system for sending control instructions to the electronic control system according to original input movement signal; besides, the computer system also obtains the GPS information received by the GPS receiver so as to obtain the GPS system-monitored result of 2D motion of the moving platform. By comparing the monitored result with the motion signal of the moving platform, the invention obtains the monitoring accuracy of the GPS system.
本发明公开了一种二维动态校准台,用于校准布设在结构物上的GPS系统,包括:一支承框架;一运动平台;一双层双向运动机构,设置在该支承框架和该运动平台之间,用于驱动该运动平台沿正交的两个方向作二维运动;一电子控制系统,设置在该支承框架上,用于控制该双层双向运动机构的驱动动作;GPS接收机,其设置在该支承框架上;和一计算机系统,用于根据原始输入的运动信号,向该电子控制系统发出控制指令;同时,该计算机系统还获取该GPS接收机接收到的GPS信息;从而得出该GPS系统对该运动平台的二维运动的监测结果,并通过将该监测结果与运动平台的运动信号相比较,得出该GPS系统的监测精度。
