So I live in the GPS world. I am a Topcon GPS guy, but I run into Trimble constantly. Currently the Topcon is 400mhz and the Trimble is typically 900mhz, but the issue isn't as much converting 900 to 400. It's more the "talk" of the radio. Currently Topcon uses what is referred as RTCM 3.X. And Trimble uses CMR, CMR , and CMRx. I would like to know how to convert CMRx to something I can use as a Topcon guy. Something I can convert to RTCM3.x but maybe I just do not understand what those formats stand for or how they actually work. I am attempting to receive and decide CMRx so I can use it for RTCM 3.x. Anybody that can help with this? I know it's a long shot.
