 This project allows you to track cell phones periodically. For instance every minute or every five minutes. You can watch the cell phone being tracked in real time using google maps and you can store and reload routes easily. You have the choice of two server stacks. Either using asp.net and sql server or using php and mysql. Historically, devs have downloaded the asp.net server project 2 to 1 over the php project. I have included both now in the same download but you only need to use one.

针对长输管道地理坐标定位问题，提出了一种基于组合导航技术并应用管道磁标处地理 信息进行分段修正的管道地理坐标定位算法． 该算法基于惯导/里程仪组合导航的基本原理，应用 误差模型对航迹误差进行修正． 通过研究陀螺仪和里程仪的误差特性，建立了陀螺仪和里程仪的 误差模型，针对低精度加速度计应用于惯性导航系统时存在速度和航迹解算误差较大的问题，提 出了应用加速度信息对里程仪速度进行修正的速度解算方法． 实验结果表明，算法解算所得位置 误差为0. 16%，可为长输管道提供三维地理坐标定位信息．
