Well, I don't know if it's the most suitable, but we had
good success with using
PostGIS->Mapserver->HTML/JavaScript+Browser

We've implemented a system to track ships in the Caspian Sea
and overlay daily MODIS imagery for ice monitoring.  And
we've done a few sites to monitor land-based vehicles in
remote locations...

We don't have a site exposed for public viewing, but you may
find some others via Google.  A couple of non-mapserver
implementations: https://star-traxx.com/ and
