POB Magazine And Javad

> Is Javad pushing too hard or are we being too complacent?
He must have some backers who are financing his research, production, and marketing. No doubt these backers demand that he push hard.

I've never actually seen a Javad receiver in the flesh. So I put it down to "sound and fury, signifying nothing".

Okay Mr. Blue Sky, where do I insert my $0.10?

Wow, he really did a 180° - and not very long ago, either. :-S

Dr. Henry Wild designed the Wild Heerbrugg line of theodolites: T-1, T-2, T-3, T-4, etc. I heard of a story that once they got the factory started and the machinery tooled up, Dr. Wild had a change of heart and wanted everything re-done according to his NEW design which he thought was far superior. The backers of Wild Heerbrugg refused, so he moved from Heerbrugg to AArau and gave his NEW design to Kern.

Some people have more than one idea.

Hey! He has a new new 864 channel receiver that will track around a 140 satellites at one time!!! o.O

OK guy..

:good:

Oh yeah?

Considering he is spending as much money as he is on ads, and I don't think I have ever seen one operating our area, it makes me wonder what is going on....

If I were Light Squared I'd be trying to get a GPS company to show how easy it is to get around the issues caused if Light Squared gets licensed, and to promote that technology.

Oh yeah? No immediate miracles.

As a freshly minted member of the established press, it would seem incumbent upon you to fully research this issue and report on your findings. I think you'll find that about half of what you are suggesting is untrue. There are two issues in this- science and policy. Science is verifiable while policy is debatable. I've spoken with Javad about this personally and recently. He found a solution and had that solution tested by an independent third party laboratory (his words). He also worked out an arrangement that LS would install GNSS receivers at selected sites to provide rtn access inexpensively (again his words). The precise gps band requires 30mhz while the ca code band is only 2mhz wide. Manufacturers have been filtering 150mhz. He discovered this in his own receivers and fixed it admitting to his mistake (his words) It's like they've been selling tickets to a picnic on someone else's property for years and get upset when the property owner (the citizens of the US) try to reclaim it. I personally have mixed feelings about it. I have a few receivers that exceed 10 years in age. I'm not excited about them no longer working even though we seldom use them. But then I think what other tech am I still using that is that old? Implementing light squared could have been more costly than it was worth. It's a debate worth having. Unfortunately we never got past the science. Furthermore we all know that the DoD was who turned the music off on this dance because ls ostensibly interfered with military GNSS. If this is true we should be concerned. If it isn't we should be concerned. If it's true it reveals a dangerous vulnerability. If it's not true it reveals that someone influenced the military's position.

Dear Norman,
My good friend, a well known respected PLS, insisted that I respond to your "without a doubt " comment.

I don't have now and never had a "backer". I had a short technical contract with Lightsquared to prove that filter technology to protect GPS existed. I did that and the contract finished a long time ago. If you find any money that I received from a "backer", multiply it by 10 and I will donate to you or a charity of your choice. All my advertisements are paid fully by myself.

I also did not do a 180. I wrote that 30 Mhz wide band of GPS must be protected. Then I noticed our filters were 150 Mhz wide.

If you want to know more of the truth, write me at javad@javad.com

I do things that I believe in my heart. No one can pay me to say or do things that I believe not to be 100% true.

Regards,
Javad

As long as I know if it's been genetically engineered, or not, it's all good.....:-D

Oh yeah? No immediate miracles.

You'll find no argument from me regarding delayed implementation nor if it should have been implemented at all. My initial thoughts about this ran to the airline industry as well and for the same reasons. Components are cheap but safety of life certifications are not nor is installation.

All of these issues are political. What sacrifices are acceptable for what perceived gain... all within fair limits of healthy debate. As Javad has said the science is not debatable. It is provable. According to him filters are available to prevent the interference light squared threatened to create. This was my only point as well as clarifying the 180 issue as it was misleading. It is all largely moot now of course but perhaps history will benefit from clear recounting of the facts.

I also have great respect for you Gavin and respect your knowledge. It excites me to see you heading Professional Surveyor.

I wrote the "Light Squared Attack" when I heard the results of the tests that others had done. In a phone call ( from the director of an organization) I was told about the test results and I was asked to write a letter to FCC within 12 hours to protect GPS. I did write to FCC within few hours of the request to block LightSquared and wrote the "LightSquared Attack" article. I wrote the whole 30 MHz wide band of GPS should be protected because we needed the whole 30 MHz band (unlike the 2 MHz wide of low cost receivers which had passed the test).

Then I tested myself and found that our filters were 150 MHz wide. Way more than 30 MHz. Others wrote that the technology to build narrow filters did not exist. We worked intensely for a few weeks and proved that we could build it. I was then invited by our official government body to PNT (government meeting) and presented results in two meetings to about 30 high level scientists in Washington DC. No questions remained un-answered. Several independent organizations, including US Air Force, tested our units.

Later I pushed LightSquared for two things (if they get authorization): 1) Put about 400 RTK GNSS reference stations in their stations across the US for the high precision GNSS users at a fraction of current charges (a US nationwide RTK network, at charge of $300 (three hundred) per year). 2) Charge GPS high precision user community whole sale price for their LTE network (same as they would sell to Sprint and others; much less than we pay to AT&T and others). This would have saved RTK users more than $3,000 per year, plus a US nationwide reliable RTK network all over US. We were working in that direction and I worked with LightSquared engineers on technical details. That is when I wrote "LightSquared is a gem".

Having a functional GNSS receiver AT THEIR STATIONS would have guaranteed that receivers further away would have not get affected. IMHO It was the best thing for the GPS community in the long run.

With my suggested retrofit plan, manufacturers would have not lost any money and RTK users (including owners of old units) would have ended up over $15,000 in their pockets in 5 years plus latest modern GNSS unit NOW from their selected manufacturer .

All these messages got lost in political noises and intense lobbying; and by those who repeated words of others without verifying.

I leave it at this, because some details of "hiding the truth" are pretty ugly and more political that you may imagine.

I know all are tired of hearing about this subject. I kept silent for months. Some of my friends that knew the story encouraged me to write it for the audience of this site. I write it, because I can prove it.

There are many areas where we can get RTK correction from the state DOT at no or little cost to the user. Florida, any many other states have free or low cost network RTK. If LSQ had gone through with their plan, I'd say there is a good chance that politicians would have scrapped the State run RTK networks rather than buying a new system to replace the prematurely "obsolete" one. Regardless, I can't see how having to convert my Hipers to paper weights (maybe I could have sold them cheap to a country that protected GNSS), buy new equipment (20K?), and then potentially pay $300/year for something I was already getting for free, is going to result in a windfall of $15,000 for me in 5 years.

Further, since LSQ had no plans to build out in rural areas, and I'm willing to bet that most urban areas already have an RTK network, I fail to see how they were really adding any new network RTK functionality into the mix, but rather, just finding a way to disrupt, then undercut, the current suppliers. And even further, I'm pretty sure there are over 100 free DOT stations in Florida, so 400 LSQ RTK stations nationwide sounds like a tiny reward for such a huge disruption and loss of business capital and public infrastructure. Honestly, from the beginning, this sounds like a huge burden and something I should not be in favor of.

Regardless, thanks for taking the time for posting here and giving your side of story. If true, some of the positive elements you were working on never came out. Maybe people would not have been so hard on Javad if they had put out press releases to explain some of this?
