That looks like a perfectly normal GPS data string.  You're lucky it's 
not some wierd proprietary binary format!  You should be able to feed it 
into a serial port separate from the one your TNC is using, and then set 
UIview to use the port under "Setup, GPS Setup".   I.E you will require 
TWO serial ports (or USB-to-serial "dongles") on your PC -- one for the 
TNC and one for the GPS.  

Not sure which GPS "sentences" UI-View actually requires.  Can you 
enable $GPRMC and $GPGLL as well?  (These two sentences are required to 
get speed and altitude into an APRS posit.)
