The dynamics of orbit uncertainty in an unstable orbital environment are discussed with specific application to the orbit determination of a halo orbit about the Earth{Sun L1 point. This article documents a simplified orbit determination covariance program developed under Telecommunications and Mission Operations Division Technology support. The program is ideally suited to investigate spacecraft trajectory navigation in challenging environments, where the basic dynamics of the trajectory can no longer be modeled using near-Keplerian motion.

链路路径损耗包括距离相关的路径损耗，阴影衰落，快衰落和天线增益。仿真考虑了域频 和时域快速信道变化。在每个RB中，信道（TX和RX天线之间的链路）被假定为具有零均值的复杂性白高斯随机变量，这在RB的频率范围内（180千赫）和 1 毫秒的持续时间内是恒定的。相邻的RB和时间间隔之间的信道变动是独立的。

分层空时码的自己编写的zf分解检测程序，包括判决无误和判决有误差两种情况-Layered space-time codes zf prepared by decomposition of their own testing procedures, including the accurate judgments and sentences a margin of error of two cases

今年上半年我为现公司一款流量计产品编写的上位机Modbus通讯程序（下位机程序也是我用C编写的，由于受到法律许可限制，在此不能上传，不过在将来我会把设计思路传上共享），包括自创的Modbus协议的Delphi实现及其完整调用，还有一份我编写的该产品的完整的Modbus协议说明书，非常有参考价值。-First half of this year the company I am now prepared a flowmeter products PC Modbus communications procedures (the procedures are under-bit machine I use C prepared, because of license restrictions by law, can not upload here, but I will in the future design ideas Chuan-share), including self-Modbus protocol Delphi to achieve their full call, there is also a preparation of the product I am a complete Modbus protocol specification, a very good reference material.
