Problems solved by technology

Although the above can achieve high-precision positioning, RTK equipment is expensive
[0004] For most scenes in life that do not require high-precision positioning requirements, the use of RTK equipment for positioning is not worth the loss. At the same time, ordinary terminals cannot meet the requirements due to the low positioning accuracy.

Abstract

The invention discloses a GNSS receiver, and a positioning system and method based on the GNSS receiver. The GNSS receiver comprises a GNSS board card, a GNSS antenna and a main control board. The GNSS board card is communicated and connected to the GNSS antenna and the main control board. The GNSS antenna collects the wireless signal of a satellite and sends the wireless signal to the GNSS boardcard. The GNSS board card generates an original receiver positioning information according to the wireless signal. The main control board sends the original receiver positioning information to a terminal after receiving a positioning request from the terminal. The main control board receives differential information which is generated by a CORS station according to the original receiver positioning information and which is forwarded by the terminal and sends the differential information to the GNSS board card. The GNSS board card generates the corrected receiver positioning information according to the differential information. In the invention, high precision positioning is realized and simultaneously cost is reduced, and portability is possessed.

Description

technical field [0001] Embodiments of the present invention relate to positioning technologies, and in particular to a GNSS receiver, a positioning system and method based on a GNSS receiver. Background technique [0002] RTK (Real-time Kinematic, carrier difference technology) is a differential technology for real-time processing of carrier phase measurements of two measuring stations. It can provide real-time three-dimensional positioning results of the measuring station in the specified coordinate system, and reach the centimeter or even millimeter level. positioning accuracy. Based on this, RTK-based receivers (referred to as RTK receivers) are widely used in the fields of navigation and surveying and mapping. [0003] In the prior art, in the case of high-precision measurement, the RTK receiver usually uses the network 1+1 or station 1+1 working mode, that is, it is assumed that an RTK receiver is used as a base station, and the difference is sent through the network o...
