ETA on Linux and Galileo

Javad coulda put up a nice "splash screen" to make it look like "it's doin em all!".
I suspect some developers "went that route". At least, in measure.
I'd druther have "the ugly truth", than a beautiful lie. We all in this group would.
We selected Javad for this reason, in the first place.

And here's the follow up, which may describe the difficulty for Javad a bit better:
https://insidegnss.com/gps-alliance-asks-fcc-to-reconsider-denial-of-galileo-e6-signal/

I mean you spend years developing a solution including E6 band based on statements from Gov. that it will not interfere with Galileo use in U.S. and now it's restricted. Can't release the product without being in violation and must either completely change it for U.S. use or wait and hope for a revision of FCC ruling. Geez! Oops, checked Triumph LS specs and E6 not being tracked, so maybe this not an issue.

A lot of that kind of thing is beyond me.
One thing I know. How well does a coord value repeat? And, is the gps receiver giving me good error estimate values?
A poor man is better than a liar.

I agree, just wanted to get more information out there, folks seem to be wanting it.
To summarize all the links: Ligado (formerly lightsquared) (and possibly others such as Trimble) has lobbied against Galileo use in the U.S. to the tune of Millions of dollars the past few years. FCC compromised and allowed all but E6 (which is in the band Ligado wants to use). So, while manufacturers have had access to Galileo codes and such for maybe a year and a half to try coming up with ways to implement it; it's only been about 6 weeks that they have known what will be allowed in the U.S.. Along the way, government decisions have been postponed or delayed, and that's passed on to manufacturers which is passed on to us users. The Javad development team is the best in the business, but can't control these things.

If you did as I did, and bought a 3 pack. LS, T-2, and a radio, you still have a pretty good system. It pretty well won't lie to you. It is a faithful system.
Javad at al is expecting to be able to include more constellations. This has to mean that SOME of the resources in the LS get re-allocated. Will this mean an overall gain? Probably/maybe. I hope it does.
But, it does mean that the next generation of tools will be incredible. The T-3 has radio in it. I know, not a big one. But, we'll be able to run "short range" without a radio, or 3rd component. And, I'm sure, by then our dear LS will be a lot smarter, able to operate J-mate, etc.
But, I still ain't goin' Trimbull!
Happy New Year!

The current chip will handle all constellations. The question is a matter of implementation - the strategy for dividing the work between the six engines in the most productive way. We may not know for sure until more testing is done.

It's unlikely that one engine can process all signals from all constellations efficiently in our current engine scheme. Dividing different signals from different constellations in different combinations may prove to be the superior approach. Time will tell.

So, this approach requires a re-write of the software, in the gnss chip? I'm guessing this will then be implemented via the internet, just like J-field updates?
Not to put any pressure anywhere, but when?

Hopefully sooner than later. A lot of states are upgrading their RTN's to broadcast Galileo corrections. I know NC had upgraded about 1/2 of their CORS to broadcast the Galileo constellation corrections. So that means that All the of the NC RTN broadcast GPS, Glonass and now 1/2 the state is starting to get Galileo corrections. I am with Nate, can we get a realistic estimate on when?

James,
If we had it, we'd give it. We've passed along estimates that were passed along to us and it's led to understandable frustration. I can say they are making good progress. There are alpha versions being tested by a few right now. I'm not one of them yet. It is a high priority issue and it is more complex than it would seem.

Nate, GNSS firmware has always been part of the automatic updates to the Triumph-LS.

Truth be told...

(Where's that video!)

I'm not champing at the bit, like some others are. If it were available tomorrow, I could not use it. My plan is to keep on using what I have, even when it becomes available. When the bit champers start singing about how great it is, then I'll see about getting a T-3, and utilizing it. Until then, I'm not under pressure. If I'd bought a T-1M, then I would be more anxious.
I'm thankful to have one of the best gps's made, but good stuff takes time.
