Feel free to add marine, GPS, and NMEA related files - but please send me email (to email@example.com) so that I can add the necessary info to this file. Please place any uploads in sundae.triumf.ca/pub/peter/incoming.
This site (ftp://sundae.triumf.ca/pub/peter/index.html) is mirrored in Germany at
ftp://ftp-i2.informatik.rwth-aachen.de/pub/arnd/GPS/peter/index.html. European readers may find that site easier to access.
It is also mirrored here at Vancouver Webpages using HTTP, which might be quicker for some North American users depending on the state of the net.

Navigate is a Windows program from Paul Mouland (firstname.lastname@example.org). It will receive NMEA data from a GPS and plot the position and track on a bitmap chart (you supply the charts). It will automatically select the best available chart file from those available. You can build waypoint lists and routes in the program, and it will display the appropriate navigation information.
