Preplan variable polling control satellite communication method and system

Abstract

The invention discloses a preplan variable polling control satellite communication method and system. The method comprises: a community composed of a master station, a management base station and a plurality of slave stations establishes a point to multi-point communication mode under the organization distribution of frequency division multiple access, the master station controls the data transceiving states of the slave stations according to a polling control preplan draught in advance and transceives data with the slave stations, and each slave station transceives data according to the control of the master station and transmits data within the service time slot endowed by the polling control preplan, thereby realizing time division multiplexing of shared satellite resources. Further, the polling control preplan is edited in advance by the master station, and can be modified and retransmitted. The polling control preplan can divide slave station services into common services and important services, and can also comprise priority setting and delay starting of service data. The method and the system can realize time division design of shared satellite resources, realize quasi real-time transmission and quickest back transmission of data, and guarantee the fairness and accuracy of data back transmission.

Description

technical field [0001] The invention belongs to the control field of satellite communication service data transmission, and in particular relates to a polling control satellite communication method and system with variable preplans. Background technique [0002] After decades of development of satellite ground terminals, the industry standardization is becoming more and more perfect, the modularization of components is getting higher and higher, the social division of labor is becoming more and more detailed, and the product cost is greatly reduced, which provides a solid foundation for the large-scale use of satellite ground communication terminals ; With the widespread use of large-scale integrated circuits, the terminal design has gradually realized miniaturization, integration, and portability, which has contributed to the use of satellite communications tending to be flat, large-scale, and quantitative, and the number of users has increased dramatically. [0003] Since ...
