基于高级在轨系统的可重构复接器的设计

随着空间科学技术的快速发展,航天器的数据传输系统的任务变得日益复杂。传统复接器所支持的业务类型比较单一,其复用方式和调度策略往往都是固定不可变的。本文采用CCSDS建议的高级在轨系统(AOS)体制,设计一个可重构复接器,支持多种业务类型,兼容多种复用方式。通过配置寄存器的方式重构其复用方式和调度策略,具有极大的灵活性。

Implementation of reconfigurable multiplexer using advance orbit system

Following the fast development of space science technology, the data transfer system of spacecraft becomes more and more complex. Traditional multiplexer only supports one or two types of services, and its multiplexing method and scheduling strategy can not be changed during the space mission. Using the advance orbit system suggested by CCSDS, this paper introduces a method to design a reconfigurable multiplexer which supports four types of services and is compatible for three multiplexing methods. The mult...
