You may be thinking of Scott Miller N1VG's  (of Argent Data and OpenTracker 
fame)   OpenTRAC   protocol. It was proposed as an alternative to the 
increasingly kludged APRS protocol.  It was intensively discussed on this list 
in the 2003-2004 time frame, but apparently went nowhere.   It's website still 
exists at:


but there appears to have been no activity for nearly 20 years.     A standards 
document IS on the web site that you might find useful as a starting point for 
your project.
