Last month, a Russian Soyuz ST-B rocket has launched from the French Guiana space base in Kourou carrying the first ever six OneWeb satellites. OneWeb is a planned 648 constellation of satellites providing satellite internet globally.

And a possible OneWeb user terminal. Looks familiar:

(tap USER TERMINAL)
User terminal will vary in size, but I can imagine at least a ATV/backpack configuration with Wi-Fi coverage directly to an external GNSS receiver.
This means that Justin will be able to process multi-constellation static data using RTCM 3.x messages from CORS or any other base, right in the field, anywhere in the world. The processing power from the server side could eliminate some actual "tryings to move the processing for the extra constellations to the Linux system instead of the GNSS chip". And the "strategy for dividing the work between the six engines in the most productive way" could be handle by the server with any scenario we want.
Dear friends, I was able to saw the power of 5G network during a live holographic rock concert, here. Now I doubt that a 2.5kg GNSS receiver is the right device for surveying in the field, after 2020. 5G ready network and broadband from space could change everything. I love and respect Javad receivers but right now I think we could better focus for some proof-of-concept demos/videos with Justin multi-signal multi-constellations RTK++ processing engine through a "relay service" in a broadband configuration.
Keeping the LS form factor with some minimal inside interface and server side RTK++ will increase processing power with multi-signals/multi-constellations/limitless channels and will reduce weight/price, also keeping in use a slightly modified J-Field onboard software.
