Fargo ND | Here's the deal... RTK data is generic and there are really only three different protocols all the GPS manufacturer's use. They are RTCM, RTCA, and CMR. In the beginning of RTK most transmitted using RTCA but have begun to switch to CMR+. What you get here is that you can have anybody's receiver setup as a BASE station transmitting the data in one of the three formats than the Rover setup to accept that format. In example you could setup a Deere receiver to transmit as a base sending in a CMR+ format than setup your Trimble or Beeline receiver to accept CMR+ data. GPS receivers don't care who they get their corrections from as long as its in an accepted format. Now here is the problem.... each of the AG GPS systems use different radios. A trimble radio won't talk to a Deere or a Beeline and Vice Versa. If they would agree to a radio design than this would be a piece of cake and one base in any area would supply everyone's needs. Survey industry has been this way for a long time using UHF radios from Pac Crest for most the GPS suppliers out there.
Most receivers have an extra serial port or two on the them and if you wanted you could hook up a beeline radio (which is supplied by Freewave Tech) and hook it to an extra Com port on a trimble receiver and set that port to transmit CMR or RTCA and the Beeline would pick it up. So you would have two radios hooked to one receiver both broadcasting corrections.
I work with a 35 tower RTK setup in the Red River Valley of North Dakota and Minnesota. We currently are putting a trimble, beeline, and Deere receiver on every tower. I have been an advocate of getting the radios standardized for this reason. | |
