Antonio's software works ok, but it's an executable for Windows and Linux. So, you need a PC computer in terrain during GPS survey. And that's a problem because notebook computers are not very usable when used outdoor. I thought it would be good to have the same capabilities on my palmtop computer, but I didn't want to be bound to one specific type, so I decided to port gar2rnx software to Java language. That way it could be possible to use gar2rnx / Java on almost everything: from Unix workstation to smart cellular phone (like Nokia 9210). And, of course, on palmtop.
