João,
  there are severel approaches to do that, We use:
1. Communication program reading data from GPS, converting to needed
coordinate system and then sending to Internet explorer (OLE or DDE) where
location is shown in java applet above the Mapserver map. The advantage of
this is that GPS cursor position may be *continuosly* moved on the screen
without redrawing underlying map.

2. Sending position to server and storing it there (in relational database,
shapefiles or text file) and independently creating Maserver map (e.g. using
mapscript) to show these points. Advantage is enabling to show more GPS
etc... You can use mapservers built-in projection mechanism to get
cartographic coordinates.

3. Sending position to server with using inline features (GPS coordinates)
and then getting map from mapserver. You can also use projection mechanism
from mapserver here.

  Friends,
  I am developing an application, that from a position GPS, I must insert a
point in the map and visualize the image of my cartographic base with this
signaled point. Somebody could give a suggestion to me of as to make this?
  Thanks
  João Paulo
