Embodiment Construction

[0049] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of systems and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0050] The present invention proposes the Beidou high-precision service coding method aiming at the most commonly used virtual reference station method in network RTK technology. The principle of network RTK virtual reference station technology is as follows: figure 1 shown. The user terminal U is in the reference station network and can communicate with the data processing center throug...

Abstract

The invention relates to a service coding method and system for Beidou navigation in transportation. The method comprises the following steps of encoding service data to be sent to a user terminal according to a preset coding mode, wherein the preset coding mode comprises a step of encoding the service data to corresponding observation value messages and virtual reference station description messages according to different satellite navigation system types and message group signal types, and each satellite navigation system corresponds to the observation value messages of four different message group signal types; sending the coded data to the user terminal; and controlling the user terminal to decode according to an encoding protocol corresponding to the preset coding mode in order to obtain the coded data. According to the technical scheme, the data transmission amount is reduced, the message protocol format is simplified, and standardized customization requirements are provided forhigh-precision service coding of receiver analysis of the user terminal in the transportation industry.

Description

technical field [0001] The present disclosure relates to the technical field of satellite navigation, and in particular to a service coding method and system for Beidou navigation in transportation. Background technique [0002] The transportation industry has the characteristics of "many points, long lines, wide area, and mobile". It is the largest application field of satellite navigation systems. Because satellite navigation systems can provide positioning, navigation, and timing services all day The modern comprehensive transportation system occupies an important position in the development process, and is widely used in highway, waterway, civil aviation, railway supervision, command, dispatch and other fields, and has achieved significant economic and social benefits. Relying on the support of the national Beidou industrial policy, the transportation industry has become the industry with the first popularization of Beidou applications, the largest number and the widest ...
