Abstract

The invention relates to a GPS positioning differential base station device. The device comprises a shell, an integrated main board is arranged in the shell, a voltage-stabilized source module, a three-star positioning differential module and a serial port output module are arranged on the integrated main board, the voltage-stabilized source module is electrically connected with the three-star positioning differential module and the serial port output module, three-star multi-frequency chips are arranged on the three-star positioning differential module, the serial port output module is connected to a data output connecting tube on the front end surface of the shell, and wing plates are arranged on the two side faces of the shell. The device has high signal stability, only one base stationis needed, the installation is convenient, and the cost is reduced.

Description

technical field [0001] The invention relates to a motor vehicle driver examination system, in particular to a GPS positioning difference base station device. Background technique [0002] With the rapid development of the modern driving test field, intelligence is more and more favored by people, and the requirements for the motor vehicle driver test system are getting higher and higher, especially for the positioning and orientation requirements of the vehicle. But with regard to the positioning and orientation devices in the field of driving test at present, most of them are single-satellite multi-frequency (such as GPS navigation) or double-satellite multi-frequency (such as GPS navigation and BDS navigation), and the accuracy is not very high. [0003] Since most of the existing positioning and orientation devices are single-satellite multi-frequency or dual-satellite multi-frequency, this is not suitable in some places with high requirements, wide sites or obstacles, so...
