I am working on a fleet tracking app for the cab company I dispatch for. This app would involve USB GPS units transmitting periodic position updates via 3G. This info would be used to show car positions on a map (ala VehiclePath), along with showing dispatchers the ETA for the vehicles to pickup locations, and possibly used as a meter system.

I would appreciate any pointers to good low-to-medium level info on working with the ActiveX control. One question in particular - is it possible to pull live GPS position info out of the control, so it can be used as real-time nav in the car and for unit tracking?

MapPoint EULA excerpt:.
<
For MapPoint 2010 and MapPoint with GPS Locator (“MapPoint”), you may not provide real-time vehicle guidance. You may not calculate or recommend a route or ordering of destinations based on the location of more than one vehicle.

For MapPoint, you may connect the licensed device to the systems of your vehicle only to receive power or use its audio system to output the software’s voice-based guidance notifications. You may not use the software to interface with those vehicle systems in any other manner.

I believe the time between signals isn't very long, though.

Hi,

For unit tracking you can display pushpins at each position of the vehicles. And yes indeed you may check EULA which changes with each version. I think there is also a fleet version of mappoint.
