  I'd like to see what you've written, but I cannot reach your home page.
For whatever the reason, Navigator halts at the domain (mitglied.tripod.de)
and will not display any pages below that.

  My needs for the GPS software are mission planning and differential
correction. In many areas where we work (particularly in Oregon and
Washington, west of the Cascade Mountains), I can receive the real-time
correction signal from the US Coast Guard transmitters. This gives me
differentially-corrected positional readings (horizontal accuracy +/- 30 cm;
vertical accuracy +/- 60-90 cm) which I suppose I could download directly to
GRASS. However, when I have to differentially correct by post-processing the
raw data, I still need the software from my GPS vendor.
