Psikey, everyone has product complaints. Yet these technologies march on. GPS systems are used everywhere. For architecture, engineering, navigation, map making, surveying… on and on and on. They work, they are relied on, and they are testable.
Were you aware of this? Were you aware that GPS systems are in use by everything and everybody.
I have owned a hand held GPS. A friend of mine has one in his car that he can attach to his bike. I own a 100 megahertz dual-trace Tektronix oscilloscope. I started making my living in electronics in 1972.
If you want to believe that anyone that disagrees with you is ignorant and or STUPID be my guest.
But if someone is going camping in the woods or hiking cross country then an error of 15 to 100 feet in a GPS may be totally irrelevant. But when you are driving down a 4 lane highway can the GPS tell which lane you are in? I don’t doubt that on a cost basis that the GPSes in 2005 were better than those in 2001 and the current ones are better than those from 2005.
But look at the circles in that Galaxy crop circle. I bet an error of 5 feet would make an easily visible asymmetry in the pattern. It is not my fault that you want to come up with simple explanations that have potential flaws that are child’s play to point out.
That is one of my problems with people that make a big deal about crop circles. I would think the big circles would be easy to survey once they were found and some kind of percentage of error from perfection could be computed. But I have never seen anyone mention that. They mostly just show pretty pictures and talk a lot of speculative paranormal bullshit. I am not interested in speculative bullshit FROM EITHER SIDE OF THE ISSUE. If someone wants to CLAIM it could be done with GPSes then the precision of the devices is obviously important just from casual observation of the big crop circles.
If I don’t know I admit I DO NOT KNOW..
But just because I don’t know does not keep me from admitting that it is
But where are the pictures of these crop circle artists working on huge partially completed works that had to take DAYS to make?
In its most accurate mode, GPS can determine location within a fraction of a foot. This level of accuracy could pose a national security risk, according to military experts. To prevent misuse of GPS, the military implemented a feature in the GPS signal called “Selective Availability” (SA). When SA is “on”, the accuracy of normal GPS receivers is degraded to about 150 feet by the inclusion of false position data. The civilian demand for more accurate GPS data resulted in the Federal Aviation Administration and Coast Guard implementing what is know as Differential GPS (DGPS). DGPS, which is accurate to within 2 meters, uses a receiver at a fixed location to broadcast corrections to nearby mobile receivers. Since these corrections eliminate the effect of SA, the military has agreed to eventually turn SA off. Until that happens, sailors with conventional GPS receivers will have to live with the reduced accuracy.
So civilian GPS is deliberately not as accurate as it could be in the interests of NATIONAL SECURITY. So is it accurate enough for crop circles?
