Problems solved by technology

For example, celestial navigation is to determine its own position and course by observing the position of celestial bodies. This method has simple equipment, but is limited by meteorological conditions; radio navigation is to receive radio waves sent by coast stations to determine the position of the ship itself. Although it Unaffected by weather conditions, but difficult for long-distance voyages due to the limited range of radio waves; other navigation methods are not satisfactory

Abstract

The invention relates to a regional satellite communication navigation multimedia transmission exchange control system. The system comprises a transmission exchange system which is a CAPS-based multimedia exchange system serving as a control center of multimedia service logic with various types and used for controlling and continuing various services; a video monitoring system which has conference control functions and supports multimedia conferences and multi-part communication; and a video conferencing system which enables sound, images, figures, data and text mode information to be transmitted or interacted. Through adoption of the system, the channel time delay is long, the utilization rate of resources or channels is high, network topology and routing is simple, and the broadcast scope is wide.

Description

technical field [0001] The invention relates to a regional satellite communication navigation multimedia transmission switching control system. Background technique [0002] With the progress of mankind and the development of science and technology, mankind has invented a variety of navigation methods in production and life practice. For example, celestial navigation is to determine its own position and course by observing the position of celestial bodies. This method has simple equipment, but is limited by meteorological conditions; radio navigation is to receive radio waves sent by coast stations to determine the position of the ship itself. Although it Not affected by weather conditions, but due to the limited propagation distance of radio waves, it is difficult to use for long-distance voyages; other navigation methods are not satisfactory. Judging from the current technical level and the foreseeable future, satellite navigation technology is an ideal navigation tool. ...
