U220-模块协议规范 北斗定位模块 对与GPS+BD开发者有参考价值。(U220- module protocol specification BD module)

说明：  关于GPS中BOC信号的产生，功率谱密度仿真，自相关函数以及与C/A码的互相关仿真程序。能够有效的对BOC信号的特性进行分析(On the GPS in the BOC signal generation, power spectral density simulation, the autocorrelation function as well as with the C/A code cross-correlation simulation program. Of the BOC can effectively analyze the characteristics of the signal)

单点定位就是根据一台接收机的观测数据来确定接收机位置的方式，它只能采用伪距观测量，可用于车船等的概略导航定位。(Single point positioning is based on observations of a receiver to determine the position of the receiver way, it only can use the false distance measurements, can be used to approximate the travel and other navigation and positioning)

SWAT模型的源代码。分布式水文模型SWAT在水文中享有较高的盛誉，它能够综合反映一个地区的水文地质状况，以及水文气象状况，而其源代码更是研究SWAT的必备“神器”，学习了解SWAT的源代码不仅可以在最短的时间内学习到SWAT的“精要”，更能学习其Fortran语言，了解模型到代码的转换，更能学习到其模型的“实质”。(Source code of SWAT model. The distributed hydrological model SWAT enjoys a high reputation in the hydrology, it can reflect a regional hydrogeological condition, and the hydrological and meteorological condition, and its source code is an essential artifact of SWAT, learn SWAT source code can learn not only to SWAT in the shortest time. "The essence of" better learning Fortran language, understand the conversion model to code, can learn the essence of the model "".)
