Problems solved by technology

The vertical delay of all grid points occupies 9*320=2880 bits in total, and the vertical delay error index occupies 4*320=1280 bits in total. If all these information are sent to the user terminal, the user cannot use all the information, then It causes a waste of traffic resources and will also affect the quality of service of mobile communications

Embodiment Construction

[0020] The solution of the present invention will be described in detail below in combination with the preferred embodiments thereof.

[0021] figure 1 A schematic flowchart of an embodiment of a method for processing positioning assistance information in the information processing method of the present invention is shown in .

[0022] Such as figure 1 As shown, the method in this embodiment includes steps:

[0023] S101: Calculate the coordinates (latitude and longitude) of the piercing point corresponding to the satellite according to the elevation angle, azimuth angle and other parameters formed by the user and the visible satellite;

[0024] Through the ephemeris and other auxiliary information transmitted through the network, the satellites visible to the user terminal are determined, and the connection between the terminal and the visible satellites has an intersection point in the ionosphere, which is called a piercing point, such as figure 2 shown.

[0025] The fo...

Abstract

The invention provides a method for processing auxiliary positioning information. The method comprises the steps as follows: piercing point coordinates corresponding to a satellite are calculated according to parameters such as evaluation angles, azimuth angles and the like which are formed by a user terminal and the visible satellite; numbers of grid points falling into a circle which adopts the piercing point coordinates as a circle center and a first preset distance as a radius are obtained; and deferred messages corresponding to the obtained grid point numbers are sent to the user terminal. The method can greatly reduce data size transmission of the auxiliary positioning information of the user terminal, so that the user terminal can obtain credible auxiliary positioning information with minimum data size, and the service quality of mobile communication is improved. Meanwhile, the invention further provides an information processing module and a terminal.

Description

technical field [0001] The invention relates to the field of satellite navigation, in particular to a processing method for positioning auxiliary information, an information processing module and a terminal. Background technique [0002] With the continuous development of navigation technology and communication technology, people have higher and higher requirements for location services. In order to improve the service quality of location and realize fast and accurate positioning, the navigation technology Network, the positioning assistance information is sent to the user terminal through the base station to improve the positioning efficiency and accuracy, which is A-BDS in our country. The correction of the ionosphere is also included, and the grid ionosphere is used to correct the positioning accuracy. [0003] The grid ionospheric correction model is a grid drawn at intervals of 5 degrees in the longitude and latitude directions of a certain area. Each grid point has a ...
