Embodiment Construction
[0041] An embodiment of the present invention is given below to describe it in detail.
[0042] Such as figure 1 As shown, the present invention discloses a multivariate composite weighted modeling and calculation method for satellite communication traffic, and the flow chart of the traffic estimation method is as follows figure 1 shown, including the following steps:
[0043] S1, analyze the topographic factors affecting broadband low-orbit satellite communication traffic, and establish a topographic business model;
[0044] Plains, mountains, forests, deserts, and oceans are scattered across the earth. In plain areas, the construction of ground optical fiber networks is relatively complete, which can achieve communication coverage. In remote areas such as mountains, deserts, and oceans, the information infrastructure is weak. It is necessary to realize the transmission of information through satellite communication; different continents have different levels of economic de...

The invention discloses a multivariate composite weighted modeling and calculation method of satellite communication business volume. Firstly, it analyzes the business volume terrain influence factors, value area, day and night influence factors and sudden business event influence factors, and establishes terrain business model and regional business volume respectively. Model, traffic time weighting model and burst business weighting model; then calculate the sub-satellite point position, and use the visible function between the satellite and the user to calculate the grid set within the satellite coverage; then determine the terrain of each grid Business volume, regional traffic volume and time weighting factor; then determine whether to add emergency business events; finally add the topographic traffic volume in the grid to the regional traffic volume, and multiply by each weighting factor, so as to get the satellite coverage area total business volume. The method of the invention fully considers the demand characteristics such as the value attribute and the burst attribute of the business volume, and can provide important support and basis for the configuration design of the satellite communication constellation.
Description
technical field [0001] The invention belongs to the field of satellite communication, in particular to a multivariate composite weighted modeling and calculation method of satellite communication traffic. Background technique [0002] With the rapid development of aerospace technology and satellite communication technology, broadband LEO constellations have become a hot spot for research and development and construction by many national and international institutions. To build a broadband LEO satellite constellation, the design of the satellite constellation must be completed first, and traffic estimation is one of the important links in constellation design. The design and planning of key parameters such as constellation orbit distribution, number of satellites, and satellite communication capabilities can be better carried out on the premise of mastering the traffic distribution and demand conditions. Therefore, it is necessary to accurately estimate the traffic volume of ...
