我们正在开发具有成本效益的车辆跟踪系统,据我所知,使用 GPS 跟踪车辆成本更高。所以我们正在寻求开发使用成本更低的GPRS系统。
我怀疑是否可以仅使用 GPRS(根本不使用 GPS)来跟踪车辆。这是否可能。如果我错了,如果您有任何文档或链接有用,请更正。
在此先感谢,马赫什
If you don't need an exact location you can use cell tower information and some external api to get the coordinates for each tower. It's the same function that google uses in their mobile Maps application.
