This article sounds well, but how everything is related together?

Bandwidth precedes data rates just as highways come before traffic. Doubling the bandwidth is like adding twice the number of lanes on a highway. The trends of the past and the predictions for the future indicate that data rates have been doubling ever…

I found your post comments while searching Google. Very relevant especially as this is not an issue which a lot of peaople are conversant with.

my post was a fact based refutation of your assertion that GPS are virtually infallible. They’re not, and there are reasonable doubts about the reliance of GPS systems, especially when the data are filtered through one of the contenders of an hostile situation. I did left out some facts (the article in wiki is really extense and accurate), as the one that the one disclosing (partially) the GPS system for civilian usage (I understand civilian as non-american military here) was due to not other than Reagan.

Wait a moment. Reagan and Iran? You can bet that there are security measures in the GPS standard (security as in military control of the accurate data flow), and I’m sure as h3ll that the USA has means to embargo the GPS service to regions or countries, based in the technology they use. It’s the typical paranoid mentality of the USA GOP (this and prior ones). And the USA controls the technology sold.

Aside of that, the GPS system help GPS receivers to place themselves globally, but don’t forget radars. I’m sure too that Iran has a good couple radars in their coast and vessels, so locating a ship in the sea isn’t an only GPS matter. Look, I’m contradicting my previous argument here? No, not really. I was only stating that the GPS system IS NOT 100% reliable, and in fact, subject to manipulation.

I’m defending Iran either? No, not so much as raising doubts about the USA behaviour. Is Iran acting as a bully and not reliable? For sure. But admit it, as of today, the USA has no better credibility than Iran, and this is thanks to the last 6 years policy. Your two countries are acting like schoolyard bullies, and you’re hellbent to war. And a mayority of the people of the globe is against war. But hey, you love to drive humvees in deserts under a rain of bullets and IEDs exploding left and right, it’s a manly man dream.

Note also that the doubts raised against the USA integrity here have the same credibility that the ones of Iran creating weapon grade uranium.

I agree with you there. Pitiful act. Just another reason I won’t vote for her.

Has she no shame?

Also, the GPS devices being used, were they Northrop/ Grumman? Were they part of an FBCB2 suite? What were the Iranians using? Were they using US/GPS? Were they using Russian/GPS? How did every one end up in the exact same place at the same time? Did the US/UK plant “remote control” devices on the Iranian vessels? WHAT PROOF HAVE THE IRANIANS PROVIDED TO SHOW THAT THE BRITS WERE IN THEIR WATERS? What about not only the NAVISTAR but the POSNAV readings?

Yes, for civilian models of GPS there is a deviation. Just like in the military models. Just maybe not the same amount. There is also a certain amount of deviation when using a map and compass. That is why a map has a declination diagram at the bottom. Could you hit an apple on persons head with an arrow from 300 meters? That is essentially what a GPS Satellite is trying to do.

But, for the record, I have seen the location of where the Brit position was. It appears that they were in Iraqi waters (and within appropriate declination of the GPS/NAVISTAR and POSNAV, not Iranian. And this is not the first time the Iranians have done this.

From wiki:

Developed by the United States Department of Defense, it is officially named NAVSTAR GPS (NAVigation Satellite Timing And Ranging Global Positioning System). The satellite constellation is managed by the United States Air Force 50th Space Wing.

Oh! The system was made by te DoD and actually is controled by the USAF!

To being completely fair, LET’S remember how the GPS system works: a series of USA satellites (at least three for every measurement) give its coordinates to every GPS device, to help the device determine its position. The information of the satellites must be then deciphered and interpreted by the GPS system.

Let’s remember also (don’t forget to explain this, hacker bob), that the technology sold for civil uses (and most probably for other countries’ use) makes the use of it far less accurate. As a matter of fact, many hitchhickers’ magazines inform of this deviation of civilian GPS. A deliberate deviation is introduced in non-military GPS receivers.

Also from wiki:

Calculating a position with the P(Y) signal is generally similar in concept, assuming one can decrypt it. The encryption is essentially a safety mechanism; if a signal can be successfully decrypted, it is reasonable to assume it is a real signal being sent by a GPS satellite. In comparison, civil receivers are highly vulnerable to spoofing since correctly formatted C/A signals can be generated using readily available signal generators. RAIM features will not help, since RAIM only checks the signals from a navigational perspective.

Oh! The GPS system can be fooled with false signals!

And also from wiki:

Jamming of any radio navigation system, including satellite based navigation, is possible. The U.S. Air Force conducted GPS jamming exercises in 2003 and they also have GPS anti-spoofing capabilities. In 2002, a detailed description of how to build a short range GPS L1 C/A jammer was published in Phrack issue 60[13] by an anonymous author. There has also been at least one well-documented case of unintentional jamming, tracing back to a malfunctioning TV antenna preamplifier.[14] If stronger signals were generated intentionally, they could potentially interfere with aviation GPS receivers within line of sight. According to John Ruley, of AVweb, “IFR pilots should have a fallback plan in case of a GPS malfunction”.[15] Receiver Autonomous Integrity Monitoring (RAIM), a feature of some aviation and marine receivers, is designed to provide a warning to the user if jamming or another problem is detected. GPS signals can also be interfered with by natural geomagnetic storms, predominantly at high latitudes.[16]

So a GPS signal can be jammed, the USAF conducted GPS jamming exercises in 2003, and a simple TV antenna amplifier can jam a GPS signal.

hacker bob, swear me that the british or USA military aren’t playing with the GPS precission of the Irani vessels, to force an invasion of the Iraqi territorial waters. And please, save me the “We are the good guys” explanation.

Oh French Canadian!

Hi Sharon, hugged a nice birch for you today. Blessings.

As I understand, the Brits were only armed with side arms (pistol) and were traveling in a small craft that they used to board a merchant vessel for routine inspection ( a practice that has been going on for years).

15 Sailors and Marines in a RIB (Rigid Inflatable Boat) only armed with sidearms are not in a position to “battle it out” with a patrol boat. That would not be bravery, but suicide.

And yes, the GPS/ “Blue Force Tracking” devices say they were in IRAQI waters, not Iranian. These devices are accurate, at sea, to within 100 meters (in most cases.) I work with these every day so I know they are VERY accurate.
