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