A Working Front Page, please stand by

Soon to be the home of DSRCtools.com  and/or  DGPStools.com

A site for DSRC message sets, tools, source code,
and support for those using the SAE J2735 DSRC Message Set
At this time this site is used only by SCSC staff.
A similar site for our RTK, DGPS, NTRIP
and RTKLIB work will also be created. 
As with the above, still in beta development at this this.
You can find our NTRIP caster for open public use at here at the default port.
If you have a mountPt you wish to have added, please contact Jay at the below.
If you need an SAE J2735 stream for testing, please contact Jay at the below.

Developed code for DSRC, DGPS, RTK, and other GNSS items can also be found here.
All ASN.1 and XML and C/C++ code is still to be found at the www.ITSware.net site
SAE now has an official site to get the final published J2735 ASN.1, see here
