Future Plans
Our future plans are to distribute RTCM-104 messages over the
internet. This will probably get the form of UDP messages linked
to a specific TCP/IP port. The aim is that on the mobile site,
you can run a program that is accessing that port to receive the
RTCM-104 messages, after which you either send that data through
a serial port to you differential GPS unit, or you use it for your
own differential corrections.
Of course I realize that to have a mobile GPS and PC with a life
internet connection is not for everybody feasible. However giving
products like data-roaming, such a solution is not that far away
anymore. The advantage is that after equipping your notebook with
a wireless modem, you don't need any special receiver.
Another approach could be to use normal cellular phones and modems
for the connection with the ISP.
For any questions or suggestions, please send and
email to Willem van Schaik.
