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