Embodiment Construction

[0020] The technical means or technical effects involved in the present disclosure will be further described below. Obviously, the provided examples (or implementations) are only some of the implementations that the present disclosure intends to cover, but not all of them. All other embodiments that can be obtained by those skilled in the art based on the embodiments in the present disclosure and the explicit or implied representations of the pictures and texts will fall within the protection scope of the present disclosure.

[0021] In one aspect, the present disclosure proposes a method for obtaining positioning error data, which includes the following steps: obtaining the first positioning data of the measured positioner in multiple epochs, which includes influencing factor data and first coordinate values; obtaining standard The second positioning data of the locator in the same plurality of epochs, which includes a second coordinate value; in response to the instruction fo...

Abstract

The invention relates to the technical field of satellite positioning, and discloses a method for acquiring positioning error data. The method comprises the following steps of: acquiring first positioning data of a measured positioner in a plurality of epochs, acquiring second positioning data of a standard positioner in the same epochs, and correspondingly processing a second coordinate value inresponse to an instruction of determining a positioning state to obtain a standard coordinate value; according to the first coordinate value and the standard coordinate value, performing calculation to obtain a positioning error value of the measured positioner in the plurality of epochs; and associating the positioning error value of each epoch with influence factor data, and then performing storing to obtain a positioning error data set. The invention has the technical effects that: in the acquisition method, the automation degree of data collection and processing is higher, the requirementfor the site is relatively low, meanwhile, the obtained positioning data can reflect numerical value changes of influence factors of the measured positioner in different states, and help can be provided for analyzing positioning errors more sufficiently and more dimensionally.

Description

technical field [0001] The present disclosure relates to the technical field of satellite positioning, and in particular to an acquisition method, device and processing method of positioning error data. Background technique [0002] More and more user terminals (such as mobile phones, portable computers or car navigation equipment, etc.) have satellite positioning functions, but in the process of satellite positioning (hereinafter referred to as "positioning"), due to the influence of external factors, high-precision The positioning results of the mobile terminal, such as the relative position transmission change between the satellite and the mobile terminal, and the satellite signal propagation process being blocked by trees or tall buildings, etc., will affect the positioning accuracy of the mobile terminal. [0003] The positioning error data is generally used to evaluate the performance of the user terminal in satellite positioning. In the prior art, the positioning erro...
