Embodiment 1
[0039] An adaptive satellite communication device includes various satellite communication monitoring units, an attitude monitoring unit and an adaptive communication control unit.
[0040] Such as image 3 A variety of satellite communication monitoring units include GPS positioning monitoring module, Beidou satellite communication monitoring module, Iridium satellite communication monitoring module, Tiantong satellite communication monitoring module and satellite communication monitoring data analysis module.
[0041] The GPS positioning monitoring module is used to collect current GPS positioning information at a fixed frequency, sort out valid data, and send it back to the satellite communication monitoring data analysis module in real time. This module uses the ublox-GPS chip as the core acquisition component, and is independently developed on the basis of combining the STM32F1 series platform control chip, signal noise reduction circuit, amplifier circuit and antenna man...
Embodiment 2
[0056] A link intelligent selection method, including a method for processing satellite communication link index data and a calculation method for optimal path selection;
[0057] The processing method of satellite communication link index data is as follows:
[0058] First, combine the data sent back from various satellite communication monitoring modules and attitude monitoring modules to the adaptive communication control module for data analysis;
[0059] Secondly, by comparing with the satellite communication quality standard, cross-comparing the communication quality of different satellite communication channels under the current communication posture again, and finally sorting to form a dynamic communication link table;

Abstract
The invention relates to adaptive satellite communication equipment and an intelligent link selection method thereof. The adaptive satellite communication equipment comprises a plurality of satellite communication monitoring systems, an attitude monitoring system, a link preferential selection system and a self-adaptive communication control system. The satellite communication monitoring system is used for analyzing and processing information data such as wave beam irradiation areas, pointing precision and quality factors of various satellite communication modes, so that a function of providing real-time accurate basic analysis data for the link preferential selection system is realized; the attitude monitoring system is used for realizing a function of monitoring attitude information of transverse and longitudinal communication angles and communication orientations of the satellite communication module in real time; and according to the adaptive satellite communication equipment constructed by the invention, the satellite communication requirement of a large-range area can be met, multiple satellite communication modes are realized, the practical problems of small coverage area and poor communication quality of a single satellite communication mode are reduced, the satellite communication quality is improved, the satellite communication cost is reduced, and the equipment is suitable for various user terminal devices and is suitable for popularization and application.
Description
technical field [0001] The invention belongs to the technical field of satellite communication, and in particular relates to an adaptive satellite communication device and a link intelligent selection method. Background technique [0002] With the in-depth advancement of marine scientific research, the technology of marine mobile observation platforms has developed rapidly. Ocean observation equipment, including underwater gliders, autonomous underwater vehicles (AUVs), Argo buoys, etc., are used in environments with extreme communication conditions, and the means of communication can only be satellite communications. At present, the communication equipment based on the Iridium satellite module of the United States is widely used. In actual use, there are problems such as delay, poor signal, high tariff, and poor communication quality in the Chinese sea area. As domestic Beidou satellite modules, Tiantong satellite modules, and Guanlan satellite modules have been launched s...
