RTK self-solution GNSS receiver

Abstract

The invention provides a RTK self-solution GNSS receiver which comprises a CPU module; the CPU module is connected with a plurality of GNSS modules, and the plurality of GNSS modules are connected with a power divider; the power divider is connected with a GPS satellite antenna; the CPU module is also provided with a plurality of wiring ports; one GNSS module of the plurality of GNSS modules is used as a base station, and the other GNSS module is used as a mobile station. The invention can improve the stability and reliability of the equipment working under the complex environment. Differential data sources are obtained from within the receiver, which are not subject to external equipment, and are not dependent on the network or the radio station; the receiver automatically realizes RTK self-solution.

Description

technical field [0001] The invention relates to the field of GNSS receivers, in particular to an RTK self-calculating GNSS receiver. Background technique [0002] With the continuous development of GNSS and RTK technology, there are more and more implementation schemes for RTK calculation of GNSS receivers. The traditional differential data transmission schemes include radio stations, mobile networks, wired networks, etc., and some other data transmission schemes There are also some applications for short-range solutions such as Bluetooth. However, these solutions all rely on external differential data sources without exception. There are fewer RTK solutions based on internal differential data sources. [0003] There is following shortcoming in prior art: [0004] The acquisition of RTK measurement differential data sources is overly dependent on external equipment modules. In traditional RTK measurement, the differential data required by the receiver of the mobile stati...

AI Technical Summary

Problems solved by technology

The structure of the receiver with RTK measurement function is complex, the cost is high, and the internal noise interference is serious. The traditional RTK receiver integrates a total of multiple communication devices and modules, such as 3G / 4G network modules, radio modules, Bluetooth / WIFI modules, etc., resulting in reception The cost of the machine is expensive and the structure is complex. The problem caused by many network and communication modules is that the internal noise interference of the receiver is serious, which affects the signal quality of the GNSS board positioning module.
