VC系统下,地球坐标转换的源代码,在WGS
VC系统下,地球坐标转换的源代码,在WGS-84坐标和北京54坐标之间的一套转换参数,可以全国通用的，在每个地方会不一样，因为它们是两个不同的椭球基准。-VC system, the Earth coordinates conversion source code, the WGS-84 coordinates and coordinate between Beijing 54 set conversion parameters can be nationwide, in every place to be different, because they are two different ellipsoid benchmarks.

跳频信号系统的仿真
说明： 跳频通信系统的仿真，其中还有误比特分析参数设置，误bit率分析（通过在不同的信噪比下传输多个帧做统计分析，可以通过增加传输帧数目获取更加精确的误比特率；更改信噪比获取不同信噪比下的性能），误bit率曲线(Simulation of frequency hopping communication system, including bit error analysis parameter setting, bit error rate analysis (through statistical analysis of transmitting multiple frames under different SNR, more accurate bit error rate can be obtained by increasing the number of transmitted frames; performance under different SNR can be obtained by changing SNR), and bit error rate curve)

Slip-ratio-based methods are commonly used to control
the wheel torque such that the wheel dynamics is stabilized
and the desired traction/braking force is attained; however,
slip-ratio-based controllers are incompetent for precise longitudinal
tire force tracking due to nonparametric tire model uncertainties.
