From what has been posted previously here about Javad, I am skeptical that this is a "fix" but rather a means to know whether the GPS signal has been compromised by interfering signals of Ligthsquared (or other sources), enabling the user to disregard a corrupted signal.
It looked like it would work, but I didn't see anything about roadway staking.
Javad has been an industry leader for as long as I've been surveying, and is apparently also a very astute businessman as well. He has consistently been at the bleeding edge of the industry, sells his present design to one of the big boys, then releases the next design that makes his old stuff obsolete.
I don't believe there is anyone more qualified to fix the incompatibility issues, hopefully this will allow both LightSquared and GPS to continue to evolve without conflict.
The only thing that is certain is time and technology marches on, and we cannot expect our 15 and 20 year old equipment to work forever. Get current, or get left behind.
> Javad sold out ... we should be showing a unified front against LightSquared. Love that Javad is conspiring with Lightsquared to disable your current gear, then offering to "fix" your old recievers for $800 each ...
Yes they did. Sorry to have to break this to you, but that is how things work here on Planet Earth.

Serious question; how much precision and accuracy does the military need to do what it does? Survey grade? Mapping grade? Recreational grade?

It doesn't matter if the signal is overwhelmed.
All I'm saying is that priority #1 for GPS users/manufactures should be forcing LSQ to change their plans to something that doesn't disable current GPS devices. Javad is actively giving LSQ ammo to say "Problem solved", when in fact, it's only solved for future equipment (maybe), or at a cost of 10s of millions of dollars to "fix" all the existing equipment.
Besides, Javad doesn't say they are going to "fix" everyones equipment for $300. It's start at $300 for their equipment, and goes up from there. They didn't quote a price for fixing Topcon, Trimble, Ashtech, etc ... Do you really think anyone is going to "fix" a Locus or Stratus, which are older equipment, but which still work as well as when they were made? I doubt it.
> Get current, or get left behind.
As far as I know, their isn't a single RTK device that's ever been sold that is LSQ compatible. It's not a matter of using 15 year old recievers... RTK systems sold yesterday won't work, either.

My guess is that Javad's "fix" is a precise filter that goes between the antenna and the receiver, so that it will work with many older receivers without requiring surgery. Integrated receiver/antenna systems (e.g., Locus, Stratus, Hiper, 4800, 5800, R7, R8) would require a more involved (= expensive) application.
I believe something like Jim Frame mentioned above that could be a generic application. I'm not certain of the details, but he claims to have a solution.
Trust me, I'm using 15 year old technology exclusively and dread having to spend the money to upgrade, so I understand your frustration. I guess I'm always in search of the win/win situation, where both cheap broadband and a stable GPS constellation can exist side by side.
How about this win-win? There are many other boradband plans in the works that will not affect GNSS. How about the FCC stops the LSQ plan and then the upgrades replacements are not rammed down our throats and at our expense.
A good long term plan could see someday a plan like LSQ's in that band when the constellations reach full upgrade and there has been sufficient time to develop solutions for all segments of GNSSS use, not just the questionable generic soltuion (yet to be tested) that only serves as another weapon by LSQ. This current fast track will be at our expense.
I have said it since I met him 23 years ago, Javad is one of the most genius and talented electrical engineers that walks the planet. He has suffered some on his business ventures as he has admitted of "having his head in the box, or in the lab" but this recent ploy is brilliant. Design a fix and offer not only to upgrade his equipment, but offer it for all of the other high precision GPS receivers plus why not give them some more channels of GNSS. Makes you wonder who is working for a fix at the other manufactures, or maybe they were hoping to call their recievers obsolete and have everyone pony up to new boxes. Hey, kinda like TGO and the WAVE processor, why patch it when we can force people to buy a new upgrade.
Right on Javad Ashee... I encourage everyone to look at the Javad upgrades as a way of supporting a man who was in this LightSquared fight for a win-win fix. The RTK is going to blaze with LightSquared coverage for data com as long as the filter in the receivers works. I don't doubt Javad has come up with that fix.
