Abstract

The invention discloses a cross-platform converged communication method in a satellite-ground integrated frequency hopping satellite system, and belongs to the technical field of satellite communication. Aiming at comprehensive application of different types of platforms such as vehicles, ships, helicopters, unmanned aerial vehicles and the like in a satellite-ground integrated frequency hopping satellite communication system, uplink and downlink transmission parameters are configured as required, time slots in an uplink carrier group and a downlink carrier are divided and distributed, and theuplink and downlink transmission parameters are changed by time slots. Specialty requirements of different types of platforms are met, and cross-platform converged communication based on unified carriers and signal frames in an uplink and a downlink is achieved. Under the condition of meeting the comprehensive application requirements of various platforms, the equipment implementation complexityand cost can be reduced, and meanwhile, the system resource utilization rate and the platform application flexibility are improved.

Description

technical field [0001] The invention relates to a cross-platform fusion communication method in a satellite-ground integrated frequency-hopping satellite system, belonging to the technical field of satellite communication. Background technique [0002] With the expansion of application requirements and the development and construction of satellite communication systems, the application of satellite communication in the civilian field has become increasingly widespread, gradually expanding from ground fixed applications to vehicles, ships, aircraft and other types of platform applications. Therefore, the design of the satellite communication system is required to fully consider the particularities of different platforms such as vehicles, ships, helicopters, and drones, so as to meet the needs of satellite communication for multiple platforms. [0003] At present, the application of different types of platforms in satellite communication mainly uses different frequency bands o...
