[arm-allstar] BBB/Pi or RTCM

Thu Nov 19 17:26:40 EST 2015

People have stated over and over throughout the thread that the RTCM is the only Allstar compatible device that votes and simulcasts. So asking if Sam if he is using a RTCM for simulcasting or not shows that either you aren't reading people's posts all the way through or you are in the first week of trying to kick a bad caffeine habit. Please don't feel victimized because people grow sick of repeating themselves. 

The documentation on the RTCMs and the voting mechanics of app_rpt is very well done, and answers all of your questions. Many newbies have deployed RTCM systems from design to finish with no help whatsoever from the group, so one would think that a system administrator would have much less of a problem grasping the basics.

Our server is in a commercial data center now but it doesn’t need to be. It could be a RPi2 at one site and they would all talk one another. Our site vendor has 25 linked sites. Doing this would lower the latency. I assume that we could then run a remote base that could talk up to a site that allow other Allstar nodes into the system using a different node number.

That allows for proper GPS timing between the allstar server and the master RTCM.   In some cases people don't run any radios on this single RTCM.
