Embodiment Construction

[0026] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0027] This embodiment provides a method for using ionospheric delay correction parameters, such as figure 1 As shown, the method for using the ionospheric delay correction parameter includes steps S102 to S104.

[0028] Step S102: the terminal acquires multiple sets of ionospheric delay correction parameters.

[0029] Step S104: The terminal selects an ionospheric delay correction parameter set suitable for the area where the terminal is located from multiple ionospheric delay correction parameter sets to correct the ionospheric delay.

[0030] Through the above steps, the terminal acquires multiple ionospheric delay correction parameter sets, and the terminal selects an ionospheric delay correcti...

Abstract

The invention provides an ionosphere delay correction parameter usage method and device and a terminal. The method comprises the terminal obtains a plurality of ionosphere delay correction parameter sets, and the terminal selects one ionosphere delay correction parameter set which is suitable for the area where the terminal locates from the plurality of ionosphere delay correction parameter sets so as to correct ionosphere delay. Therefore, the problem that in correlative technique, since same ionosphere models and ionosphere delay correction parameters are used globally, the positioning precision is low is solved, thereby improving the positioning precision.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and terminal for using ionospheric delay correction parameters. Background technique [0002] The BeiDou (COMPASS) Navigation Satellite System is an independently developed and independently operated global satellite navigation system being implemented by China. The Beidou satellite navigation system is committed to providing global users with high-quality positioning, navigation and timing services, including open services and authorized services. The open service is to provide positioning, speed measurement and timing services to the world free of charge. The positioning accuracy is 10 meters, the speed measurement accuracy is 0.2 m / s, and the timing accuracy is 10 nanoseconds. The authorization service is to provide positioning, speed measurement, timing and communication services and system integrity information for users who need high-precision and high-re...
