Description

Space-based information comprehensive application and information distribution system based on Mesh network

Technical Field

The invention relates to a Mesh-based space-based information comprehensive application and information distribution system, and belongs to the field of aerospace.

Background

With the rapid development of satellite technology, the number and variety of in-orbit satellites have increased dramatically, and the application of satellite technology has been expanding and expanding in life. Future space is more complex, and how to comprehensively plan the space-based information becomes a research key point.

The main application of the existing space-based information comprises communication, navigation, positioning, weather, hydrology, environmental monitoring, scientific research and the like, and the data are of various types and are not uniform in standards. At present, different day-based information is not mutually communicated, and data can be obtained from a single angle. In the actual use process, a user is often caused to need a lot of operations to finish information acquisition, and the available resource space is wasted greatly.

At present, in the use process of the space-based information, a user directly acquires the space-based information through a handheld device or acquires the space-based information through a center. The user directly obtains the space-based information through the handheld device and is influenced by whether the satellite passes through the environment, whether the signal is good or not and the like, so that the use effect is greatly limited. The user can not acquire the effective information in time due to the factors such as communication time when acquiring the space-based information through the center.

The inventors found during the course of the study that:

the problems and defects existing in the current space-based information comprehensive application are as follows: the existing space-based information service cannot integrate the space-based information on a basic basis. When the user needs multidimensional information, the channels using the space-based information service can be continuously switched, so that the problems of slow information acquisition speed, non-visual information and the like are caused. When a user needs to perform contrast analysis on a plurality of similar information, the information cannot be intuitively acquired. The real-time performance of the space-based information is affected by the satellite running condition, and sometimes the real-time condition cannot be obtained.

The problems and defects existing in the current day-based information distribution are as follows: when a certain user locally generates new information, the new information cannot be shared with all other users, and the aim of intercommunication and interconnection of all information cannot be achieved. When a part of users need common space-based information, the space-based information can only be pushed to each user, and the users can not share the same information, so that satellite resources are wasted.
