The pfinder software supplied by Trimble must reverse the original
position of the easting and northing.  After collecting the GPS data
files I differentially correct the data on my PC, make a GRASS vector
ASCII file, and then send it to my unix Sparc Station via kermit.  Once
in the unix machine I move the file to the dig_ascii directory.  I
haven't needed to do any other manipulation.

I hope all this discussion helps.
