摘要

随着空间科学技术的发展，载荷数据种类和数据传输速率不断提高与数据处理传输能力不足之间的矛盾日益凸显，为了解决这一问题，设计了一种基于CCSDS AOS协议的星载数据复接器设计方案.该设计方案能够通过LVDS接口接收实时遥测数据，回放数据，以及1553B总线数据，通过RS422接口接收工程遥测数据，话音数据，并将以上各路数据复接组帧加扰下行.

Abstract

With the development of space science and technology

the contradiction between the increasing load data type and data transmission rate and the insufficient data processing and transmission capacity has become increasingly prominent. In order to solve this problem

a kind of onboard data multiplexing based on CCSDS AOS protocol is designed. The design scheme can receive real-time telemetry data

playback data through the LVDS interface

and 1553B bus data

receive engineering telemetry data and voice data through the RS422 interface. And multiplex the above data

framing

scrambling

and then downlink.
