For the tracking system, the means that can intellectively assist the fault diagnosis and maintenance is significant. Then we can avoid relying heavily on the experiences of the engineers and can reduce the probability of the event that engineers climb up to the antenna with heavy instruments when the faults turn out. For the data channel, to get the high-qualified remote sensing images, we need to get the quantitative data about how the factors influence the BER of Receiver .The data can help the design of receiver and the evaluation of the performance of a receiver. This thesis mainly contains those two parts.

对于跟踪系统，研究一套能辅助系统故障诊断及维护的智能手段是非常有意义的，这样系统维护时可以避免过多依赖技术人员的维护经验，特别是接收天线发生故障时携带仪器攀爬天线的情况；对于数据通道，面对高质量的遥感图像数据要求，我们需要得到影响接收机误码性能的各主要因素对应的量化数据，这些数据对于接收机的设计及性能评估是非常有帮助的。

The second phase of networking ,which occurred in the 1960s ,included three major milestones:software switching, digital transmission ,and satellite deployment,in 1965 ,american telephone and telegraph introduced the first stored program control local switch ,the 1 ees switching system ,with the ues of software control, a family of custom calling services (speed calling,call waiting ,call forwarding and three way calling ,etc ,) was mande possible, the first software program for the 1ees switching system had approximately 100,000 lines of codes, today switches may contain ten million lines of code.

第二阶段是网络化，其发生在20世纪60年代，包括三大里程碑：软件交换，数字传输，卫星的运用，在1965年，美国电话电报介绍第一个存储程序控制区域交换机，第1 ees交换系统中，软控制运用在家庭式的呼叫服务中（快速呼叫，呼叫等待，呼叫转接和三方呼叫等，成为可能，第一个软件程序，为1ees切换系统大约有 10万行代码今日交换系统可能含有1千万行的代码。

Applying the software ADAMS for dynamic simulation and Pro/E for three-dimensional design creates the mechanical system of virtual prototyping model of the 200t crawler crane. The models of the drag bar, the spring backstop, the luffer rope and the crawler in the system are established well by ADAMS/View module. The dynamic simulation of the complete mechanical system is researched at series of work condition, which occurs possibly the crawler crane boom backward tipping as the crawler crane unloads suddenly.
