Hello.
Check this link and these guys out. This is by far the best i've seen. I'm not sure how much they will share with you but asking never hurt anyone.

Thanks Paul,
If I've understood correctly!!! this is like many online trackers (ISS for example), in that the link points to a system that uses predictions to aim the aerial.
I don't want to use a computer simulation, just receive the NMEA 'sentence' which is used in a calculation to show where it is.
Also if I've understood correctly, the Ublox GPS sends NMEA signals. Either the same or similar, to aircraft, ships, satellites etc. I'm just beginning with this, and I think they send a 'sentence'. An example 'sentence' . $GPGLL,2222.22,N,1111.11,W,222222,A,*37 All NMEA sentences start with $GP the next three digits GLL refer to LAT/LON data they also include time. so $GPSGLL,2222.22,N,1111.11,W,222222,A,*37 would be Geographic position, latitude and longitude. [Latitude 22deg. 22.22mins. North Longitude 111 deg,11.11min. West Fix taken 22:22:22 UTC then checksum *37 (This might not be accurate, just my interpretation) I think the $ and checksum are for programming once received.
Hope all is clear?
Cheers, Camerart.
