Win Inaccuracy Mobile6 GPS

Question

I am writing an application that uses the built-in GPS on the Motorola MC75. I set it up correctly and ran the test solution that comes with the Win6 SDK. It works great, and the coordinates when connecting to Google maps select the exact location. However, the fluxes of longitude and latitude are significant (essentially, when measuring distances of 25 or so from each other). When standing, it will usually have a flow from 0.0002 to 0.0003, which is about 36 feet.

Is there a way to improve accuracy? I know that you can change QoP in a remote registry, but I'm not sure how this will change it, because I can not find any documentation.

Any suggestions? I will definitely vote for the most useful answer.

Thanks in advance. Zach

The problem with GPS is that its accuracy is up to 10 meters (10 meters = 32.808399 feet). There are technologies that help in a more accurate location, such as WAAS.

"... For example, imagine that a specific GPS receiver collected 1000 data points under ideal conditions. It can be assumed that the best data point can be accurate to 0.01 meters, and the worst, accurate to 15 meters ..." - GPS Link

Other devices use accelerometers and digital compasses to help get more "local" accuracy. Using such devices, you can fill in the gaps between GPS points to create a more fluid system.
