Data transmission method based on Tiantong satellite and broadband satellite fusion

Abstract

The invention discloses a data transmission method based on fusion of a Tiantong satellite and a broadband satellite, and the method comprises the following steps: S1, enabling a user to generate basic transmission content into Tiantong narrowband data through an application program, and transmitting the Tiantong narrowband data to a satellite broadband and narrowband fusion data gateway through a lightweight data transmission interface; and S2, broadband data transmitted by the satellite broadband indoor unit is accessed to the satellite broadband and narrowband fusion data gateway through an Ethernet module. According to the method, important data transmission is performed through link judgment and a lightweight protocol, so that the problems that the cost of an existing double-satellite data link is too high and a single broadband link is influenced by severe weather and is difficult to ensure the return of important data are solved, remote technical support before the broadband satellite terminal is opened and emergency communication requirements under special conditions are effectively ensured, and the service life of the broadband satellite terminal is prolonged. The user experience perception is improved, and the overall safety and service quality of satellite services are improved.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a data transmission method based on the integration of Tiantong satellite and broadband satellite. Background technique [0002] Tiantong Satellite is my country's first self-developed mobile communication satellite. Its satellites, chips, terminals, gateway stations and other systems are independently developed, which fills the gap in domestic independent mobile communication systems and breaks the current status of foreign satellite mobile communication services. . The satellite mobile communication system can provide users with large-scale, long-distance, flexible voice, short message, and packet data services through satellite relay and forwarding. Because the link is established quickly and the use of satellite frequencies is less affected by the weather, it can provide comprehensive coverage and emergency services. It has great advantages in communication an...

AI Technical Summary

Problems solved by technology

The broadband satellite communication system can process and transmit high-speed data, images and videos through broadband satellites, and has great advantages in emergency communications and universal services that require high-speed communications; at the same time, there are also complex satellite remote stations. , the problem that communication links are vulnerable to extreme weather

[0004] At present, in actual satellite communication cases, two different satellite resources are used as backup. Although the security has been improved, the satellite network resources are relatively scarce and expensive, and the cost is relatively large; emergency satellite broadband networks are often required before the establishment of a voice remote technical support
