However, they are usefull in mobile robotics and any autonomous vehicles. The day when the cars will become automatic vehicle under control by a highway system, then compasses will be required. There is actual research in this domain in order to obtain fluid trafic and improved safety in heavily crowded highways around big cities.

I have a legal survey which shows azimuths which can be converted to compass headings. In order to find the actual survey stobs in the ground I need a GPS that will track my direction but also show me what direction to start walking, say for 315 degrees north. Any suggestions on what unit to look for that will do this? Thanks I am interested in purchasing a large tract of land in a very mountainous area.

It is very good and very accurate and kind of worthless. The only advantage I can see is to get started on the right foot. For example, when I program a route to somewhere on my TomTom from my home, it will invariable show the wrong way to head out and immediately go around the block. Most people can see this and make the necessary correction and the GPS will quickly catch on. The same sort of problem might occur if you stop for gas and wonder which way to go. It shouldn't take a GPS to get you going in the right direction but if you do go the wrong way, it will help you correct your direction. However it may take you a long way around figuring there was some reason you left the interstate besides just stopping for gas. In short you still need to pay attention to where you are and where you came from and where you should be going. I actually HAVE an auto compas on the built in GPS in my Toyota Prius.
