Implemented in the D-PRS specification.  Reference http://www.aprs-is.net/dprs.aspx  This specification takes into account the idiosyncrasies of using the D-STAR voice protocol for data transfer.

If the HamHUD project would use the D-PRS specification, it would be reliable and able to interact with APRS clients while also receiving Icom D-STAR GPS information.  This is the significant piece that continues to be overlooked in this thread.  D-PRS is designed for APRS clients to see Icom D-STAR radios in GPS/GPS-A modes AND allow those clients to use the D-STAR data subchannel for bidirectional communications.
