That's easy to count. Let's say you log 100 bytes every second (that's
more than enough for longitude, latitude, timestamp, velocity, height
and some satellite information). Then that will be 60*60*24*100=8640000
bytes for a whole day. That's about 9M. If you just need location and
timestamp then it is 16-20 bytes per sample and can be dramatically
compacted using differential encoding.
If you are interested in Geocaching you should check the Yama map viewer
project:

It has an online Demo applet here: http://yamamap.org/demo.php
