part of the problem here is that the mappoint gps tracking REQUIRES nmea2 at a slow baud rate.

nmea2 contains a dumpload of data to transfer the satellite information (up to 12 satellites worth on most gps units).. and as far as i can figure it, mappoint doesnt even USE the satellite data. the actual lat/long data only comes once per cycle through all the nmea2 data. the bottom line is that it can only track as often as it receives that data.

if mappoint allowed nmea1 at a faster baud rate, it would be able to get the position every couple of seconds...
