Daniel:
We typically take 10-100 points per location (Pathfinder will average
them all together), and also make sure you run the differential correction
algorithm. Granted, 1997 is a bit old so I'm not entirely sure the
capabilities of the software back then -- you might want to consider
upgrading! Also, is your GPS also that old? It might not have enough
channels or receive the differential signal to post-process it much better
than about 10m.
