Description

Mesh network-based space-based information comprehensive application and information distribution system
Technical Field
The invention relates to a Mesh network-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 types of on-orbit satellites are rapidly increased, and the application of satellite technology is gradually and continuously expanded in life. The future space is more complex, and how to carry out overall planning on space-based information becomes a research focus when being called in time.
The main applications of the existing space-based information include communication, navigation, positioning, weather, hydrology, environmental monitoring, scientific research and the like, the data categories are various, and the standards are not unified. Currently, different day-based information do not intercommunicate with each other, and data can be generally obtained from only a single angle. In the actual use process, users often need many operations to complete information acquisition, and available resource space is greatly wasted.
At present, in the using process of the space-based information, a user directly obtains the space-based information through a handheld device or obtains the space-based information through a center. The user directly obtains the space-based information through the handheld device and is influenced by the conditions of whether the satellite passes through the space-based information or not, whether the signal is good or not and the like, so that the using effect is limited greatly. When a user acquires space-based information through the center, effective information often cannot be acquired in time due to factors such as communication time and the like.
The inventor finds out in the process of research that:
the problems and defects existing in the current space-based information comprehensive application are as follows: the existing space-based information service cannot perform basic integration on the space-based information. When a user needs multidimensional information, a channel using space-based information service is continuously switched, so that the problems of slow information acquisition speed, non-visual information and the like are caused. When a user needs to compare and analyze a plurality of similar information, the information cannot be intuitively acquired. The real-time performance of space-based information is influenced by the running condition of the satellite, and sometimes the real-time condition cannot be obtained.
The problems and defects existing in the distribution of space-based information at present are as follows: when a certain user locally generates new information, the new information cannot be shared with all other users, and the purpose 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 but the users cannot share the same information, which causes waste of satellite resources.
