[aprssig] Waypoints to GPS Receiver: Navigation

[gerheim at cox.net]

I finally have a GPS receiver that _receives_ NMEA data. A little experimentation has shown that the GPS receiver (GPSmap 60) attempts to uniquely name each waypoint it receives, even if they come from the same station/SSID.  

For example, waypoints from WA1XYZ-15 may be named "WA1XYZ 151", "WA1XYZ 154", etc...

This leaves about 3 questions:
1) Is there a way to navigate to a "moving target"?  If I navigate to "WA1XYZ 151", it'll keep sending me to where WA1XYZ _was_ when that waypoint was sent.  

2) Is there any rhyme or reason behind the naming convention?  I couldn't figure any out.  The characters it appended seemed to be random.  
2a) How many unique names can it associate with the same call/SSID? My guess is that it'll repeat or jam up before it runs through the complete set of valid characters.   

3)  Is there a way to identify the most recently-received waypoint?
