[ntp:questions] GPS NG type 46 refclock tests

I have just discovered that there is a new GPS NG type 46 refclock, 
which I would like to try on the Raspberry Pi.  Checking ls /dev I see 
no GPS devices listed, so I would appreciate help with how to handle 
that.  My device configured for the gpsd is /dev/ttyAMA0.  I guess 
creating some sort of permanent link would be the way to handle this, 
but my Linux knowledge is very elementary.  Would that be:

   ln -s /dev/ttyAMA0 /dev/gps0

Secondly, in the documentation "TVP" is mentioned.  It would be helpful 
if it were defined, but is not.  I guess time-velocity-position?  As I 
have those in cgps -s I appear to be covered, but what about the other 
objects?  WATCH, PPS and version are listed.  How you I know whether I 
have these?
