In RTK operation work mode (RTCM3.2) if the GNSS (base) of Virtual Reference Station mode doesn??t use the L3 signal it is useless to have a Rover that operates with that signal?
Can someone explain my doubt and tell me were can I find information about that in particular (pappers, official documentation, thesis or other).
In differential GNSS solutions ONLY common signals count, often why solutions are better with your own local base (coupled with generally shorter baselines).

Do you know were can I find some papper about that?
Many thanks!
No, BUT by definition you can only difference common signals, if they don't exist on one end of the baseline you have nothing to difference. Same as using a GPS only receiver on one end and a multi-constellation receiver on the other end, you are able to ONLY use the common GPS signals, thus a GPS only solution.

I would not hesitate to use a GNSS receiver with a L1/L2 GPS VRS. VRS allows me to know in the field that I am getting a usable position. That I can Post Process GNSS at a later date only means that usable position can get better.?ÿ
I would like to hear from GNSS Post Processors if their software could utilize 3 CORS base files, one with L1,L2,L5 GPS, another with L1,L2 GPS and Glonass and a third with L1,L2,L5 GPS and E1,E5,E6 Galileo seamlessly or must they solve three rover positions from the 3 CORS and mean the results?
zyx, you do mean L5 or are your someone getting the L3 military signal?
Adding to what Shelby Griggs said it is not just "common signals" but it also must be "common satellites" within those "common signals" to resolve differenced positions.?ÿ It is quite possible to have 3 CORS with 10 satellites each but only 6 or 7 actually common to all three for the entire observation.

First, thanks for your replys! My doubt has gone...
Paul, you are right, I have mistake, I mean the L5!
