摘要

In order to improve the data transmission efficiency of remote sensing satellite,and make full use of link re-source in remote sensing satellite data transmission with fixed rate,the remote sensing satellite data transmission technology based on link adaption is researched to improve the utilization rate of link resource. The simulation and calculation results show that,in comparison with the traditional technologies,the data transmission quantity during the remote sensing satellite transit is increased by 2.62 times while the transmitting power and transmission bandwidth maintain the same.%为提升遥感卫星数据传输的效率,针对传统遥感卫星数据传输中固定速率存在链路资源未充分利用的问题,研究基于链路自适应的遥感卫星数据传输技术,提升链路资源利用率.仿真计算结果表明,在星上发射功率和传输带宽不变的情况下,与传统方式相比,遥感卫星过境期间的数据传输量提高了2.62倍.
