"Tragic Destruction"?

No. More like intentional act of inhuman cruelty. The fighter pilot KNEW it was an airliner, not a military aircraft.

Want to find out how your ideas could help launch the next iteration of GPS technology?

Sure, you gonna provide us with a link or something?

Well, what if he had just seen "Red Dawn" ? That would make you paranoid about airliners.

The REAL story is that the Soviet's didnt want competing foreign chemtrails in their airspace.

Article fails to mention Selective Availability, which made GPS pretty useless to civilians for a lot of the things we use it for these days.  Although GPS has been around for 30 years, it's been accurate for normal people for less than half that time.

I'll take this over GPS any day.

It took the US Air Force wanting to lob a bomb through a window 7000 miles away is more like it.

Err, so the nation fighting the "Evil Empire" and trying to developer nuclear first strike capability so they could wipe the USSR off the map without fear of reprisal due to their space laser defense system wouldn't stoop to using civilian planes to launch a sneak attack against their enemy?

They didn't even follow ICAO procedures to contact the aircraft.

Paper maps are obsolete now that we have GPS? Huh? It was tiny computers that could display a map that made paper maps obsolete. GPS is compatible with paper maps and if we didn't have the same advancements in computers we'd all be using little devices that spit out GPS coordinates and looking them up on our paper maps. Don't confuse mobile Google maps with GPS technology.

A sneak attack on Sakhalin Island?  What a devastating blow that would have been to the Soviet Union....

CSB:
My dad was posted to El Segundo as part of a NATO contingent regarding GPS Navstar (that's how I always knew it not the reverse) so as a 10 year old kid moving from a small town of 8,000 outside Ottawa to L.A. it was a bit of a change. We ended up going back a year after we were posted back (I think it was 90) and drove there and were given a Magellan unit with a little magnetic egg antenna to try out. Looked like this:

Barely could get 2 satellites let alone 3.

When the Persian Gulf War 1 occured he assisted in procuring some for our ships that were sent over. The sailors were under strict orders not to play with them as they were "very important". He heard US Marines were using them to helidrop pizzas in field.

You misunderstand, like Radak explained two posts before yours, GPS itself was invented for military purposes, yes, but it was encrypted and unavailable to the public (and, more importantly, to our enemies).

After the KAL incident, Reagan decided to unlock GPS most of the way.  For the first several years thereafter, civilians and foreigners could initially not pinpoint closer than 100 metres or something, thus making it less useful for the Ruskies and Chinese to aim bombs or call-in artillery, et cet.  But 100 metres was more than good enough to keep airliners safe from crossing into forbidden territory and to keep boats and ships off of most large rocks (and to call the Coast Guard close enough to you that they could find and rescue you).

Space Command still has the ability to turn off civilian/foreign availability at the flip of a switch, in the event of war or emergency, but the fact that the switch is flipped the other way now is because of a decision not to allow another KAL 007.

That's why the Europeans wanted their own GPS sats so they couldn't be turned off or screwed with by the US.  The US told them they had to allow them access to the sats.  The Europeans told them to go pound sand.  The Europeans then found out they needed special Cesium atomic clocks only manufactured in the US.  The US said no Cesium clocks for you.  So the US can now turn off/screw with European sats too.

FTFA:And if you have to call 911 for an accident outside the store, the EMTs have your location on lock.

Gah, this seems to be the most common misconception I see these days. 911 operators DO NOT LOCATE YOUR PHONE WITH GPS

ONE plane for a sneak attack?  That would make sense for a bunch of idiots living in grass huts, not for two superpowers going at it.

Maybe they feared that it was a bomber whose  CRM 114 discriminator was damaged and couldn't pick up signals with the OPE prefix.

I thought it was the need for first strike accuracy from our ballistic missile submarine fleet that gave rise to GPS.

See my Boobies to clear up your misunderstanding.

KAL 007 had nothing to do with the creation of GPS.

It had everything to do with you, me, On-Star, and everyone else outside of the U.S. military being able to use it.

GPS NAVSTAR was around long before KAL007.

The opening up of GPS may be due to what you say but the system was up and running for years before Reagan was elected.

"A second phase of Enhanced 911 service is to allow a wireless or mobile telephone to be located.

To locate a mobile telephone geographically, there are two general approaches. One is to use some form of radiolocation from the cellular network; the other is to use a Global Positioning System receiver built into the phone itself."

I just got that from the E911 article on Wikipedia. It seems you are the one with the misconception.

If you could lob a bomb through someone's window from 7,000 miles away, ... wouldn't you want to?

There's a lot of people I'd have on my shortlist.

I should have clarified further. Federal law requires mobile phone operators to be able to locate a phone within a certain precision. The current requirements are beyond the capabilities of gps enabled phones, thus every carrier in the US has implemented various additional steps to help locate the users. These are almost all tower based technologies, they aren't using your phone's gps abilities to locate you when you dial 911.

But when are you going to show us your boobies?
