This sudden loss of position information is why many "modern"
navigation instructors (ie, those who admit that GPS exists and
teach how to use it wisely) still suggest at least periodically
logging (ie, writing down) one's position if not actually keeping a
plot.

Quoting Frank Reed: "GPS nav system often (normally?) has no hard-copy output of any sort" Depends on the receiver/system. If you lose GPS signals but the equipment is still functioning otherwise, you might be able to consult the unit's track log for the positioning history. If the unit output NMEA sentences and these were stored, they could be consulted. And you could periodically do a screen dump and save as needed. These outputs could be printed for a hard copy IF a printer was available. Perhaps on a large ship but I doubt if smaller vessels would have one. -- Richard Langley ----------------------------------------------------------------------------- | Richard B.
