Garmin GPS 45 - Limitations and/or compatibility
-Accuracy estimated to be about 30m
-Differential only works on or near the coast (possibly some other large
bodies of water)
-The Garmin GPS 45 comes with 9 pin serial port and sould easily be
hooked into the fujitsu or any other portable PC.
-I have obtained a newer model of GPS. The Garmin GPS 45 XL. I have
tested this GPS at all however. I assume it performs much the same as
the 45 except maybe a little better.
Software Issues
1. Have obtained Garmin GPS PC software, but I have not tested it at
all. I would like to evaluate it on a portable as soon as possible.
2. Have made contact with a man at GTRI who has written a Visual Basic
application that takes the coordinates of the GPS and using some
averaging technique to achieve under 5m accuracy. This would be the best
thing for our project if this works out like it has been described to
me. I am in the process of obtaining the source code now. I will turn
it over as soon as I have it. This code could give our group a great
deal of breathing room in the GPS area and allow our programmers to
concentrate heavily on Map/Tiger data programming.
3. I am not sure what the transfer rate from the GPS to the PC. I
don't consider this to be a huge software issue.
