I suppose that if anybody can solve this, it's Javad.
Don't like it ... it sounds like this solution will not be compatable with older equipment, and I doubt the manufactures are going to work with consumers to retrofit older equipment when this will give them an opportunity to sell you new gear ... I've been skeptical all along about how serious the GPS industry is in stopping LSQ, when selling new LSQ compatible GPS units will be a windfall for the industry.
er..."site"...(dang fat fingers"
Wow. I sort of guessed this was coming.
Just the other day, I watched Javad's video that discusses how LSQ affects the GPS signal and he briefly discusses a fix.
http://www.javadgnss.com/javad.com/downloads/javadgnss/video/lightsquared/LightSquared-7.mp4
It was pretty obvious to me that he would be approaching them or vise verse to discuss his "fix" and now here it comes.
The more I think about this, the more disappointed I am with Javad. The #1 priority should be making LSQ change their plans in way that does not affect existing GPS users. Javad has switched teams, and now will be feeding LSQ talking points and giving credibility to their claims that GPS and LSQ can coexist, when the fact of the matter is it’s going to put a huge burden on GPS users …
Javad has seen the opportunity here to be the first manufacture on the block with LSQ compatible GPS (if it’s even possible), and they seem to think that will be good for business. And, undoubtedly, Javad will have better access to LSQ’s technology and will have a development advantage, then patent whatever solution they come up with. If Javad helps LSQ push this through, I will remember this when it comes time to purchase a new GPS system. I don’t care if I have to wait a few extra months for Trimble or some other brand to put out their new stuff … screw Javad.
JAVAD is a very intelligent individual and a savy business man as this move has shown.
JAVAD has said LSQ MUST stay within the lower end of their spectrum and that they are the ones that need filters to keep their signal doing just that. I think Javad sees the potential for RTK corrections to be broadcast over the potential LSQD system to assist with positioning and he is thinking many years down the road. Does that help with the right now? No. Does that help with the ag industry that utilizes the Starfire/Omnistar signal. NO, One can see from the signal breakdown on Javad's site that they Starfire/Omnistar are still in the Hot scrambled zone.
AND, as you mentioned, the worst thing is this potential merger will do, is give LSQD a "I told you so" card.
Im not going to jump on the "I hate Javad" bandwagon, (like everyone is doing to today with the "I hate Facebook")
but, I am very curious on how this plays out. It does seem that the fix being presented is simply, Here, buy a JAVAD unit and your problems are solved. Logistically that solution won't work.

In other words they've outfoxed the competition, or they're trying to.
Makes me like them more.

Will this fix for the US GPS system be engineered in Russia?
I for one am glad to hear of this partnership. I watched Javad's video about this issue, and I believe that this is an engineering issue. Keep in mind that JAVAD has lots of users that use their older non-JAVAD and JAVAD equipment. Why would JAVAD cut its own customers' throats with a solution that would make ineffective all of the older equipment? I don't think it will. I think it'll solve this by allowing all the older gear to continue to be used without filters, filtering the outgoing signal at the Lightsquared source. I have contemplated the possibility that this won't be possible and that older equipment may have to be modified in order to function in conjunction with the LightSquared signal, however that may come to pass. But, I don't think Javad would take on this partnership if that was required, because it would spell the death of that company. Javad has a solution to this that will not require any modification of existing GNSS receivers. They're on top of their game on this one, and I'm glad they've partnered with LightSquared. I look forward to seeing the solution.
>filtering the outgoing signal at the Lightsquared source
The best transmitter filtering in the world will not prevent interference in a receiver that was designed only to reject satellite-strength signals in the adjacent band, when faced with strong terrestrial transmitters in that band.
Anyone who believes that a powerful ground transmission system covering a nation will not interfere with the GPS signal when using the same or nearly same bandwidth is dreaming. May start out with little interference in order to get permitted to operate, but once that is done, Katie bar the door, many past examples to look at. They need to be moved clear out of all GPS frequency's. Big money, big corruption and bending of rules is what the LS and those who pardner with them represent. Unless the military has some other guidance system on standby our defensive navigation systems will be subject to an instant scrambling of all GPS signals. Any compromise with such a potentially disruptive system is foolishness. We should be guarding those frequencies with our lives with very harsh penalties in place for those proposing construction of any system built or to be proposed being built that could compromise our GPS frequencies. Our lives may depend on those frequencies being compromised. Don't understand why this has been allowed to get as far as it has, it reeks of treason to me and those who opened the door and those who left it open to LS plans, need to be made into examples that would discourage similar proposals being ever pursued again.
The inconvenience of surveyors loosing GPS is not the main worry at all. We would get along fine, we have more known points on the surface of the Earth than we ever have had in the past to work from.

I agree, Bill. It's not a transmitter problem, it's a receiver problem. The current batch of receivers were designed with the assumption that there would not be a high powered earth based transmitter on an adjacent freq... and that was a good assumption at the time. I don't see a solution that allows LSQ go through with their plan that doesn't make older GPS equipment obsolete ....
I agree with Jud that Lightsquared has consistently upped their demands, and changed their plans on the fly. Even now are saying that using the lower end of their band is a temporary solution, which of course means that after they get thier foot in the door, they will continue to push for more use of their band until they have full use. And it amazes me the government is even considering this. There are dozens of options when it comes to communication, there is only one GPS. I can't believe the goverment is seriously considering endangering GPS for yet another communication company.
