[GPS develop] Delphi_GPS_Comp DL : 0: Here is a GPS component for your GPS navigation hobby project.The component was developed using Delphi 5 professional running with Windows XP Pro, Service pack 2. Review my comments in the source code for insight into how it works. The embedded COM port came from the public domain release of AsyncPro that was originally produced by TurboPower Software. Although it s much more complex than required, the default creation properties support NMEA communications. So, I provided only the ability to specify ComNumber, ComBaud and ComOpen. All Files required to build the COM port are included in the distribution. I changed the look of the port select dialog, the geekish wording of a few message strings and the baud rate property editor to make it compatible with the component.-Here is a GPS component for your GPS navigation hobby project.The component was developed using Delphi 5 professional running with Windows XP Pro, Service pack 2.

[GPS develop] GPS DL : 0: 在有限的实验条件下，为验证高动态软件GPS接收机信号的捕获和跟踪模型，提出了一种基于软件GPS 接收平台的高动态GPS数字中频信号模拟方法。介绍了软件GPS接收平台的基本结构框架，并根据高动态环境下伪随机码的多普勒效应及本地振荡器的频率误差对接收信号的影响，推导并建立了一种较精确的高动态GPS 数字中频信号模型。为使模型适用于更加复杂的环境，通过设置接收信号的噪声幅值来调整信噪比大小，以确定所需的信号强度；在信号参数的设置过程中调整入射信号与反射信号的幅度比值及反射信号的时间延迟参数，以模拟不同程度的多路径效应对中频信号的影响。仿真结果表明了该方法的有效性。-In order to validate the model for capturing and tracking the high dynamic signal of the software GPS receiver on limited experiment condition, a method for modeling the high dynamic numeric IF signal was presented based on the software GPS receiver platform. The basic frame of the software GPS receiver platform structure was introduced, and according to the impact of the Doppler effect of the pseudo-noise code and the frequency error of the local oscillator on the received signal in high dynamic environment, a more precise model of high dynamic GPS numeric IF signal was deduced and established. To make the model be applicable in more complicated environment, the required intensity of the signal was obtained by setting the noise’s magnitude of the received signal and adjusting the Signal-to-Noise ratio. In the process of setting the signal parameters, the ratio of the incident signal’s magnitude to the reflected one and the time delay of the reflected signal were adjust
