Well, with DGPS SA can be completely eliminated, so that'd wouldn't really work. Read the article, they talk about this very thing. Look up OmniSTAR or StarFIRE. And those are just two examples of world wide dgps, you can also get free radio corrections from the US Coast Guard in the US, or help from WAAS.
Yes, besides using different frequencies for the different bands, they are using a completely different message format and spreading their spectrum differently. I don't think the industry will have much troubles covering the cost, because it will certainly pay off in sales. Having multiple services, bands, and frequencies are a really good thing for us as consumers. Our accuracies will only go up!
There are mining companies already using GPS (google gps mining) to control trucks and to do surveying. Also, you can use GPS repeaters to blast the signal underground from the opening of the cave. It's not pretty, but it works marginally. Buildings are another problem, and all of the cell phone companies are working on it in the USA for the e911 system that requires gps locators in all cell phones by 2004, which probably won't happen. This requirement was laid down in 1996, with the first phase ending in 1998 and final phase in 2004.. of course that's probably changed by now, but IDWFACPC (I don't work for a Cell Phone company).
The satellites are NOT in a Geo-stationary orbit, so they would have to constantly be turning satellites on and off, and to top it all off, they could only command the updates while the satellites were in line of site to the ground station in US, so pretty much impossible without seriously effecting the US's use of GPS.
First off, the US can't just block out who they want with GPS, that is the beauty of it, it's a one-way connectionless communication protocol, it is either OFF or ON. Second, the US would NEVER, EVER turn OFF gps, we have much more riding on GPS than anyone else. Third, our only control over GPS at this point is Selective Availability, which besides having a presidential and congressional mandate to never turn ON again, it is completely useless with today's technology. Any corruption and error caused by SA can be eliminated with L1/L2 carrier phase tracking. That is one reason SA was turned off in the first place. The other being to jump start the civilian use of GPS to increase the technology worldwide.
I know everyone likes to think that the USA is evil in every way, but I hate that no one sees the gift that was GPS. The military could have used it all for themselves, but no.. they shared with all, and turned off SA to boot. Not only that, but they didn't hide any of the implementation details. Which also makes me wonder why the GALILEO project is costing so much, much of what was done by the US won't even have to change. And the US did it cheaper than Europe is proposing.
I do not work for the GPS JPO, but I do work in the navigation field, so I hate when people spread FUD about GPS when they really don't know what they are talking about.
By the way, if you don't believe me on the L1/L2 carrier phase tracking, look up Trimble, NavCom, Ashtech, etc. etc.
"...It [Carbon Fibre] is so tough that Kockums had to develop the cutting technology to build the Visby. "We had diamonds in the beginning but they were destroyed after a very short time," says Göthe. "What we use now is an extremely high pressure water jet. I think it is a bit incredible but a water jet is better."
Finally something that can get the coffee stains out of my mug!
Agreed. At the same time though, reality is that some people don't want change. If/When someone decides to switch to linux, it is good to know they can still open all of their old files, whether simple or feature complete in their new OS. This limits the ACTUAL amount of change they have to deal with. It's enough of a concern worrying about hardware working or not, but when you have to worry about converting all personal or corporate documents, you just about eliminated any gain from the change.
I'm just glad they didn't mention one of the *nix clients 'BitchX'. Who knows where they would take that one. Linux would be made evil *AND* misogynistic!
The whole board of directors thing is a interesting one, many companies like a diversified group on their board from all sorts of industry. The fact that they have Bill Gates on their board isn't for his knowledge of drug companies, but for his knowledge of business (whether messed up or not). The board of director guys get paid a load of money for really not doing much work. It's one of the perks of being an ex-CEO these days.
First off, I'm really bothered by all of the idiotic posts saying something along the lines of "I bet those 60% just haven't tried it." Why, just because someone doesn't agree with you, is it because they don't understand your side? Pretty egotistical.
Anyway, I love my dialup at home. $8 a month, always connects fast, and it does what I need. I spent 5 years in school getting a bs/ms in cs&ce and now spend my time programming/designing/etc 10 hours a day at work, why the hell do I need broadband at home? And why if I don't have it, is it because I don't know any better. Personally, if there is something I NEED, I download the s.o.b. onto my USB drive at work, and take it home. That saves me $35 a month that I can spend on other things. Oh, and, hold your breath, I don't have cable either. Holy shit, I must entertain myself by reading and/or spending time with my family... oh man, what a fucking looser.
May I recommend something from Barsuk or Sub-pop records. There are tons of great bands out there looking for music lovers like you. San Diego has a great radio station (not Clearchannel) that plays a lot of GOOD music. They also stream online (MS Media player ONLY unfortunately) and have a very knowledgable list of DJ's. I am not one of them, I'm just a happy listener who finally found a decent station.
94.9. Check them out at fm949sd.com They also have a recommended list of albums, of which I have not bought three, and every one of them so far has been great.
I think you'd be suprised to know who some of the readers of slashdot are and where their experiences lie.
When writing up something quick, I always put the constant first, because I know I won't want to come back and debug a 'variable = constant' comparison mistake later on. But, I guess since the airplanes I write code for, obviously run on PHP, I must not know shit.
Maybe I missed it when I read the article, but what language are they referring to when they say,
"Yet the system still runs code from 1962, written in an
archaic programming language almost no one alive understands"
?
I bet there are at least 1000 people right here on slashdot who could understand it just fine, and wouldn't mind putting a few "exceptions" in the tax code:
Microsoft technologies are the best-supported in the world, providing resources where, when and how you need them.
Have these people ever called Microsoft for customer support?
I don't consider when I need them being hours on hold, and I don't consider how I need them setting me back a couple hundred bucks.
If it was Henry, then he would have enough money to implement his plan to buy every hot woman a 357 magnum. His idea was, to give em' all guns, so the next time they're walking by a contruction site and some chicken s&*# worker yells something from 6 stories up, the woman can at least shoot back.

Indeed. And don't forget there are Russian GLONASS satellites up there as well.
Okay, let me chime in.

Indeed. I stand corrected. And somehow offtopic even considering "rich white man" was in my post about Bill gates. Go figure.

Once they start throwing white women in jail (Martha), nobody is safe, even rich white men!
Once they ruled against Martha, I knew that Michael Jackson and Kobe were screwed.

I found that wierd as well. I mean, that'd have to be a pretty hefty radar gun to pick up Mach 2!

Wow, that was a big possesive noun.
last sentence, change "not" to "now"
sorry.

I guess I don't understand your response, not to mention the fact it is way offtopic.
Did you hear somewhere that people who believe in God are supposed to be immortal here on earth?
I don't think the fact that they are dead gives any points to either side of the debate on the existance of a higher deity/creator/lord.
Who really knows, maybe their belief in God got them alot, maybe not, but certainly the fact that they are dead doesn't give rise to either answer.
Oh, and the grandparent poster forgot, L. Wall, but I guess he doesn't really belong in that list (yet).

According to all the Atkins/Southbeach/idiot diets out there, bacon IS good for you. It's got NO carbs whatsoever!! So eat away my friend!
If it was Henry, then he would have enough money to implement his plan to buy every hot woman a 357 magnum. His idea was, to give em' all guns, so the next time they're walking by a contruction site and some chicken s&*# worker yells something from 6 stories up, the woman can at least shoot back.
I thought it was a good idea.
Sorry, incredibly offtopic.
After watching 'Office Space' for the first time, I was really close to switching to a construction job. I still consider it on a bi-monthly basis.
