Problems solved by technology

[0003] However, due to the quality analysis performed by the offline receiver, if the observation quality is found to be poor in the post-event mode, it needs to be re-measured until the observation quality meets the requirements, which is time-consuming and laborious. Moreover, the offline method may also cause data loss

Embodiment Construction

[0039] In order to describe the technical content of the present invention more clearly, further description will be given below in conjunction with specific embodiments.

[0040] In order to achieve the above object, the present invention provides a GNSS receiver, which includes a receiver and a processor, the receiver is used to receive raw observation data from satellites, and the receiver may be a GNSS antenna of the GNSS receiver. The processor obtains the original observation data from the receiver, and processes the original observation data to generate a quality analysis result (for how to process the original observation data to obtain the quality analysis result, please refer to the description of the quality analysis method, which will not be repeated here).

[0041] Through the above-mentioned GNSS receiver, the original observation data can be processed online to obtain the quality analysis results. Compared with the offline offline processing method, the above-men...

Abstract

The invention relates to a GNSS receiver including a receiver and a processor. The receiver receives raw observation data from a satellite. The processor obtains the raw observation data from the receiver, processes the observation data, and generates a quality analysis result. The invention also relates to a quality analysis device including a receiver and a processor. The invention also relates to a quality analysis method. With the GNSS receiver, the quality analysis device and the quality analysis method, a data quality analysis algorithm can be written into the GNSS receiver to conduct real time online analysis of the raw observation data, so that a user can check the quality analysis result through a built-in webpage of the GNSS receiver and an LED display. And modeling is conducted on the basis of stored historical multi-path data, a predicted multi-path value of an assigned moment is deducted to reduce the influence of multiple paths, so that the method has a wider application range.

Description

technical field [0001] The present invention relates to the technical field of GNSS receivers, in particular to the technical field of observation data quality analysis of GNSS receivers, and specifically refers to a GNSS receiver, a quality analysis device and a quality analysis method. Background technique [0002] The quality of original observation data is closely related to the positioning accuracy of GNSS (Global Navigation Satellite System, Global Navigation Satellite System), which is the basis for realizing GNSS high-precision positioning. In the construction and operation phase of the continuous operation reference station network, in order to ensure the quality of GNSS solutions and the operation of the continuous reference system at the provincial level or larger areas, the observation data of the GNSS receiver must be checked for the necessary quality when selecting the site. It is of great significance to ensure the quality of system construction. Analysis and ...
