Embodiment Construction
[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0035] figure 1 It is a software implementation flowchart of the present invention, a method for planning and predicting meteor trail link based on GIS system, specifically comprising the following steps:
[0036] (1) After loading the electronic map, according to the geographic information data provided by the GIS system, select the sending end site and the receiving end site of the meteor trail link, and equip the sites with appropriate meteor trail communication equipment. Connect the icons of the two sites selected on the electronic map in pairs to complete the link building.
[0037] Such as figure 2 As shown, the specific process of establishing the meteor trail link includes the following steps:
[0038] (101) In the GIS system, select the specified electronic map file, open the map and load the geographic information data,...

The invention discloses a method for planning and predicting a meteor trail link based on a GIS (Geographic Information System) system, and belongs to the technical field of communication. The construction process of the meteor trail channel model is relatively complex, and the meteor phenomenon has a strong regionality. The traditional meteor trail link analysis method relies on the manual prediction of the operation on the map, which has a large workload, low prediction efficiency and results. Poor accuracy. In order to solve the above problems, we rely on the GIS platform and combine the specific elevation data to analyze and predict the communication quality of the planned meteor trail link, which is completely realized by the program, which is efficient, reliable and convenient. The present invention fully considers the influence of actual terrain environment on link opening, greatly improves the accuracy of site selection and link planning of meteor trails, and is especially suitable for communication stations in the design stage of meteor trails communication system under complex terrain environment address selection and link planning prediction.
Description
technical field [0001] The invention belongs to the technical field of communication, and relates to a meteor trail link planning and prediction method based on a GIS (Geographic Information System) system, and is particularly suitable for communication site selection and link planning in the design stage of a meteor trail communication system in a complex terrain environment predict. Background technique [0002] Meteor trail communication is a long-distance burst communication method, which can realize reliable information transmission with a single-hop communication distance of 500-2000km within the frequency range of 30-50MHz. As an important means of minimum emergency communication, meteor trail communication is widely used in strategic emergency communication systems in the national defense and military fields, as well as emergency communication guarantees such as meteorological data collection, hydrological monitoring, and disaster reporting in the civilian field. ...
