aprsazel

An utility to track azimuth/elevation/distance/speed/altitude of a moving 
APRS target. It prints the following information out separated by tabs:

[timestamp][server/port][target call][azimuth][elevation][distance][speed][altitude]

-c --coordinates    WGS-84 coordinates of the observer in APRS format
-s --server [name]  APRS Internet Server and port,
		    e.g. aprs.sral.fi:2345,
		    can also have an optional name,
		    e.g. aprs.sral.fi:2345 sral
-p --port	    AX.25 port, e.g. ax0 or 2m
-t --target	    station to be followed, can be multiple stations
		    separated by commas or spaces, wildcard is accepted
-z --azimuth	    show azimuth of the target (degrees)
-e --elevation	    show elevation of the target (degrees)
-d --distance	    show distance of the target (kilometres)
   --distance_miles	show distance of the target in statute miles
   --distance_nautical	show distance of the target in nautical miles
   --distance_attoparsecs    show distance of the target in attoparsecs
-g --speed	    show speed of the target (kilometres per hour)
   --speed_mph	    	show speed of the target in miles per hour
   --speed_knots	show speed of the target in knots
   --speed_furlongs	show speed of the target in furlongs per fortnight
-a --altitude  show altitude of the target (metres)
   --altitude_feet	show altitude of the target in feet
   --altitude_miles	show altitude of the target in miles
   --altitude_attoparsecs    show altitude of the target in attoparsecs
-l --all	    print all above parameters with default units (-zedga)
-v --verbose	    print some debug information
-V --version	    aprsazel version
-h --help	    prints this page
