Embodiment Construction

[0029] The present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0030] IGSO inclined geosynchronous orbit satellites, the sub-satellite point is in the shape of "8", covering high-latitude areas with high elevation angles, which is a key factor for communication in high-latitude areas. The communication method in the frequency-hopping and time-hopping data link communication system based on IGSO satellite adopts variable-speed fast frequency-hopping and time-hopping technology, which can realize fast, reliable, and trans-horizon communication between high and low latitude regions.

[0031] figure 1 It is a schematic structural diagram of an IGSO satellite-based frequency-hopping and time-hopping space-based data link system provided by an embodiment of the present invention. The system can provide services such as networked dynamic access, anti-interference relay transmission, and cross-regional data inte...

Abstract

The invention discloses a frequency hopping and time hopping data link communication system based on IGSO. The frequency hopping and time hopping data link communication system comprises an IGSO satellite, a ground service management station, a user data link terminal and a handheld terminal. The user data link terminal can be directly connected with the communication satellite; the handheld terminal can establish connection with the communication satellite through the ground service management station. The communication system adopts variable-speed quick frequency hopping, time hopping and parallel synchronous demodulation technologies, and has the characteristics of strong anti-interference capability, low time delay, high transmission rate and the like; by utilizing an inter-satellite link, three satellites can realize single coverage of about a half of the whole world, and space-ground integrated data exchange and wide-area communication between high-latitude and low-latitude regions can be realized.

Description

technical field [0001] The invention relates to the field of satellite communication, in particular to an IGSO-based frequency-hopping and time-hopping data link communication system. Background technique [0002] The IGSO (Inclined GeoSynchronous Orbit, Inclined Geosynchronous Orbit) satellite subsatellite point is "8" shape, which has relatively good coverage for high latitude areas, which just solves the problem of blind spots in high latitude areas of GEO (Geostationary Earth Orbit, Geosynchronous Orbit) satellites. disadvantages. IGSO satellites have the same orbital height as GEO satellites, and have good coverage and utilization. The IGSO satellite constellation can achieve continuous multi-satellite coverage in my country, and can achieve effective space diversity. The constellation composed of multiple IGSO satellites can achieve better coverage performance than GEO satellites. [0003] The space-based data link is a system that uses satellites to communicate betw...
