Description: 步进电动机的角位移量与输入脉冲数严格成正比，电动机转动一圈后，没有累积误差，所以步进电动机是数字控制系统常用的执行电动机，并且广泛的应用在小卫星上。为了
使步进电动机在小卫星上安全运行必需在地面做相应的检测。下面介绍在小卫星有效载荷地面检测仪中利用WindowsXP多媒体定时器实现步进电动机高精度控制的方法。-stepper motor angular displacement volume and input pulses strictly proportional to motor rotating ring, no accumulated error, the stepper motor is used digital control system implementation motor, and widely used in small satellites. To stepper motor in a small satellites necessary for safe operation on the ground do the same testing. Below introduced in a small satellite payload ground detector using Windows XP multimedia timer-- Stepping Motivation high precision control method. Platform: |

Description: 针对TCP (Transmission Control Protocol) 协议在高速卫星因特网中传输吞吐量低的问题, 提出了一种改
进TCP快速恢复的算法。该算法根据卫星信道由传输错误造成的分组丢失概率远大于由拥塞造成的分组丢失
概率的特点, 通过加快窗口的增长速度, 避免过早地进入拥塞避免阶段, 达到了提高TCP吞吐量的目的。通
过NS2软件模拟仿真了高速卫星因特网环境, 并对各个TCP版本和改进算法的仿真结果进行了比较和分析。
仿真结果表明, 改进算法的吞吐量比TCP2SACK提高了约10 , 比TCP2Reno提高了约30 。-A new algorithm is p roposed to imp rove the throughput of high speed satellite&internet network. In
satellite channels, most of lost package is due to transmission error instead of congestion. We can make some im2
p rovement on TCP (Transmission Control Protocol) fast recovery algorithm. Bymaking the window increase fas2
ter and not enter congestion avoidance too early. We imp rove the throughput of TCP. We use NS2 to simulate the
environment of satellite and internet network, and the results are compared. In simulation, about 10 through2
put in our algorithm is imp roved than TCP2SACK, and that is about 30 imp roved than TCP2Reno.
