Use of new GNSS update - Galileo

18 months ago our State RTN added two Mount Points that added GPS L5 and Galileo. The new GNSS update supporting these constellations came out recently. Are there any instructions available? I tried RTCM3.2MSM4 iMAX (network) and RTCM3.2 MSM4 Nearest. The LS does not indicate that these additional constellations are being used. The V6 screen shows only 5 0 0 4 positions. Systems & Systems Tracking screen show columns and rows of available signals. At the bottom "Independent Tracking" or "Conventional Tracking" with no explanation. Any precedures for settup or getting Galileo & L5 to work?

Matt, I presumed that yesterday's GNSS update for 3.7.6.190624 was the one that added Galileo. My mistake. For the future, are there recommended combinations of the GPS, Glonas, Galileao constellations and their individual components? I want to make the most of what we have available.

The default configuration is setup for GPS, GLONASS and Galileo. DPOS has been utilizing the new consitilations when the data is present for a over a year now.

Typically I use a set-up that connects the LS to the State RTN and click the Record GNS button when I want a static point collected with the RTN point. Until new Javad GNNS is released I am using RMAX (State Leica Network) which only processes GPS L& Glonas. In this setup there is the newer list of all the available networks and signals. These are all on. When I collect a point with Record GNNS and send it to DPOS it only comes back with using GPS and Glonas L1,L2,O1,P2. I have not been able to find a setting which includes the newer constellations into the DPOS settings.

I need to clarify. Currently only the Developer server has Galileo turned on. It can be selected in J-Field DPOS by choosing the DEBUG server and is also available online at https://dpos-dev.javad.com/jca/#/home. Galileo use was disabled in the Production server about 6 months ago because the use of Galileo was found to cause an incorrect solution in one case.

I just ran a couple files on the Developer server. The reports do no list what constellations were used. Also, the position residuals all came up 0.00. The coordinate results were consistant.
