Compared to the development of computers, or the Internet, or even cars, the evolution of aviation equipment appears to be very unhurried. Several factors contribute to this very gradual pace, but one of the most important is the extreme care with which any innovation affecting safety has to be examined, evaluated, analyzed, and tested. Satellite navigation equipment for aircraft is not an exception, so predicting its future for the next20 years is relatively easy compared to predictions for other fields. In this paper first of all we will describe briefly the challenges that satellite navigation must solve to be available solution for aviation. Then, we will describe the systems that have been developed to overcome these challenges and the performance they offer today, or will offer very soon. There is currently an explosion in satellite Navigation: before the end of this decade there will be over three times more satellites, offering civil signals in two distinct frequencies (as opposed to one today).

首先，读者可以先将DDK原来的packet例子程序备份，然后用改动后的驱动程序源码覆盖原先的代码（即覆盖packet->driver目录下的代码，修改后的代码已经给出）。 然后开始编译。顺次选择开始->程序->Development kits->Windows 2000 DDK->Checked Build Environment，将出现一个控制台窗口。使用cd命令进入D:programsNTDDK src etwork ndispacket目录（即驱动程序和相应应用程序所在的目录），键入build命令开始编译，在该目录下的dirs文件的控制下可以同时编译driver目录下的驱动程序和testapp目录下用于测试驱动程序的应用程序；即同时得到改动后的驱动程序和测试该驱动程序的应用程序。-First, readers can DDK first example of the original packet backup procedures, and then change the driver covered the original source code (that is, covering packet-gt; Driver directory code, the revised code has been given).
