I've done something for real-time shipboard positioning, it would work
pretty well for aerial as well after adjustments for speed. It would need 
to be reworked by someone to be used for real-time land-vehicle use on a 
road network, using GRASS 5.7's v.net.path et al. That would include both
updating it to work with 5.7 vectors and intergrating v.net.*.

"NOT FOR NAVIGATION, USE AT OWN RISK" 
(It's a hack, but it works fairly well)

You can underlay GIS layers & do real-time display of say soil type 
or whatever at current postion.. (broken lines are from previous tracks)

To do non-realtime vehicle routing over road networks, use GRASS 5.7 
and d.path, v.net.*
