New simple, affordable solution floated by LightSquared to solve its GPS interference problem
As we reported a while ago, interference with nearby GPS signals has plagued LightSquared's attempt to offer a wholesale LTE network. And even though the company has a huge deal with Sprint to put up a nation-wide LTE network, we recently told you that the FCC wants more testing of LightSquared's signal to see if the recent improvement seen in the GPS interference is continuing. The FCC needs LightSquared to completely solve this problem since some of the GPS interference is taking place with military equipment.

LightSquared has come up with solutions before, but this time it claims to have a "simple, affordable solution" that won't require huge changes to its network The only change will come to the GPS hardware that it is allegedly interfering with. The company has signed a pact with Javad GNSS to reconfigure the filters and linear amps on the GPS receivers and make them compatible with the bottom 10MHz of LightSquared's spectrum. According to Javad, this will solve the problem with the interference.

The selling price of the reconfigured GPS receivers would not change from the current price according to Javad, although existing units will need to be retrofitted and that will force somebody to write a check. Next month, the first pre-production units will be available for testing with High Precision receivers expected to roll out in November with precision timing devices due out in March. Javad Ashjaee, Javad GNSS founder, says that the problem is not difficult to solve and that 25 pre-production models will be available within 2 weeks. "We are not talking about hypotheticals here," he said. Assuming that the new devices work as well in preventing interference as Mr. Ashjaee states they do, we should get the definitive word from the FCC and from LightSquared.

So LightSquared's solution is to step in and make up for the deficiency in the other camp.

[the degree of deficiency is debateable since the presupposition of GPS industry guilt assumes that GPS industry should have thought ahead to install $0.05 filters to protect from signal interference that wasn't there at the time]

Should work if the GPS industry doesn't try to cut off it's nose to spite it's face.

I will post the same response to your comment as I did for someone else who had the same retarded argument. It has nothing to do with who was there first, it has to do with who is playing by the rules and who owns that spectrum and has a right to use it. Your argument would be similar to saying you own property that you have lived on for twenty years, no one had lived on the adjacent property forever so you decide to build something on it. You live there with no neighbors or no problems and your structure stands with no problems or contest from anyone. Then I come along and buy that land from the previous owner who wasn't using it, I see that you have built something on my land and ask you to remove it because I now intend on using the property I just bought. You're argument is really going to be "No, I was here first" ? My response will rightfully be "you didn't own the land then and you don't own it now you moron, get the f**k off my land!"

No worries, I like and agree with the analogy, but was wondering why I prompted that response. Funny!

What? The fix will be in the receivers that have all been working fine until LightSquared came along? No matter how inexpensive the fix could be, it is flat out wrong to retrofit everybody else (incl military,industrial and agricultural equipments)just because LQ bungled their job.

What PoopyPants said, and where's your empirical evidence of LightSquared bungling anything? They have done nothing wrong except cave in and move to a different part of the spectrum they own.

this was completely the GPS maker's fault. Not LS's. The problem is though, that the GPS that we are talking about is extremely important military/agriculture, and pretty much every industrialized thing you can think of. its pretty important GPS.

Im glad they came to a conclusion that works. I have a sneaking suspicion that we as tax payers will be fronting 99% of the bill for these replacements though.

Unless LightSquared writes the check for re-configuring existing GPS receivers, their latest idea is a non-starter. And they are going to have to prove their solution really works.

LightSquared provides the GPS services on the devices in question this applies to, they could simply pull the plug on those services and then focus on the more lucrative mobile industry.

Then the GPS devices that were stupidly built without 5 cent filters will be great paperweights and LS won't have to worry about interfering with them and we can get our improved network.

Yeah right. Try telling that little fairy tale to the U.S. DoD. If LightSquared's signal is interfering with existing GPS receivers (especially the DoD's), their proposed solution is a non-starter unless and until LightSquared is going to pick up the tab for installation of the solution.

LightSquared isn't going to be making much progress now that is appears that there's been attempts to influence Congressional testimony on this issue. The chair of the FCC invested upwards of $500K into LightSquared before being assigned to the post. President Obama is in for a less, but not insignificant sum as well. While such things are in a blind trust while they're in office, the hanky panky is pretty difficult to ignore.

@ Gawain
If the FCC can ignore ATT's donations to congressmen, then they can ignore this too.

The FCC doesn't appear to be ignoring that, but it's not germane to the reality that the FCC and DoJ is positioned against the merger. With regards to LightSquared, the House oversight committee appears to be showing an interest now, especially given the testimony of the Air Force General who cited pressure to "soften" his testimony regarding this whole LightSquared deal.

Gotta give some credit to LightSquared about their moxy though - inking deals without even having a "proof of concept" in the bag with their spectrum - that's talent.
