Why GPS for asset tracking? (Score 1)

You're going to do the asset tracking in the middle of a field, with a clear view of the horizon, right? Most users have a pretty good idea where they are currently located on the planet, and can manage to key the details in. Are you really sure you need GPS? PS. You may want to look at Psion's ruggedised handhelds which include integral bar code readers and are readily programmable using a VB style clone.
