GPS Tracking Device Beats Radar Gun in Court
MojoKid writes "According to a release issued by Rocky Mountain Tracking, an 18-year old man, Shaun Malone, was able to
successfully contest a speeding ticket in court using the data from a GPS device installed in his car. This wasn't just any old make-a-left-turn-100-feet-ahead-onto-Maple-Street GPS; this was a vehicle-tracking GPS device — the kind used by trucking fleets — or in this case, overprotective parents. The device was installed in Malone's car by his parents, and the press release makes no mention if the teenager knew that the device was installed in his vehicle at the time."
Take that, you oppressive pigs!
We've got counter-measures.
Good thing: enabling people to install these devices voluntarily to defend themselves against false claims of speeding or reckless driving.
Bad thing: having the government mandate their installation, and at some later time mandating that the data be uploaded to a central processing facility.
God invented whiskey so the Irish would not rule the world.
I believe insurance companies give discounts to drivers (especially young ones) for having gps tracking installed in their cars.
The highly accurate radio wave reflection system or the highly accurate satellite positioning system? One of you must be wrong! Machines can't lie?! MACHINES CAN'T LIE?!!??!!

The article says that he was doing 62 MPH according to the radar gun. The GPS says 45. If the GPS was right, why was the gun wrong? Bad calibration? Operator error? Dyslexia?
How many other people were caught "speeding" by the same gun,and are they planning to notify any of them that they have reason to believe the gun was wrong?
If only.
GPS device gets time from GPS satellite, not user.
is the so called professor revising his "expertise" so quickly and so radically. Now it would be interesting to know (or the court forcing him to say) on WHAT he based his first expertise and what new publicly available information made him change his mind, and why he did not make use of this information for the first written testimony. I get the feeling this guy is as much expert in GPS & radar gun, as my expertise in medicine forensic is (not much).

It's the same thing as a desktop, web client, or indeed the browser itself - the client can never be trusted.
Are the cops or the courts going to audit every GPS device or line of device code to ensure that 20 mph is *not* being deducted off what is written to the log above a certain speed?
Come to think of it, that's a great idea for OS or FSF - create code for popular GPS devices, and then produce the code for audit when you go to court contesting a ticket, while asking that the cops produce the code off of their device!!

I have a handheld Garmin GPS (with car mount) that specifications claim that it is within .75 knot accuracy on the speed display.
I used it to get out of a speeding ticket outside of El Paso. I said the GPS said I wwas doing 75, the cop said his radar gun said 76 and it is calibrated. I responded thatt my GPS uses government satellite signals. He let me go.

My thoughts...
Good Thing: Everyone thinks the output of electronic devices is the truth, the whole truth, and nothing but the truth.

If I mod you up, it doesn't necessarily mean I agree with what you've said, sorry.

A variation of this has been done in a number of DUI/DWI cases. A number of defendants have demanded that the source for the breathalyzer be made available for review by the defense.
In the cases I'm aware of, the manufacturer has refused to release the source as their agreement/license with the relevant law enforcement agency does not provide for this.
I believe the outcomes have ranged, but in general this has been a successful defense.
Only if the drivers allow themselves to be tracked at all times and allow the data to be uploaded to a location where the insurance company can monitor the data at their own whim and fancy. You are right though - I know Progressive gives discounts for kids who have GPS trackers in their vehicles.
Is new guns and their "pop" mode. Basically it is an ultrafast start and shutdown mode for the gun. The reason is, of course, RADAR detectors. They've gotten quite good. They don't necessarily need the gun to be on and transmitting to pick it up. When the gun is in standby (with it's electronics operating but not transmitting a beam) they can still be picked up. Same sort of way RADAR counterdetectors work. Even though the detector itself isn't trying to emit anything, it does anyhow (as does any superheterodyne device).
Ok, great, however you might pause to wonder about the ability to electronics operating in the 30GHz range to quickly come on and stabilise and, well, you'd be right. Guns in "pop" mode aren't accurate. In part due to the fast start, in part due to less data points, they can produce unreliable readings. The gun manufacturers say that pop mode isn't to be used as a final speed measurement, but that doesn't stop police forces from doing so anyhow.
Or it could be even more simple: The gun wasn't calibrated. Like any precision device, they need periodic recalibration. Had this been allowed to happen, it is entirely possible the gun was producing inaccurate readings.
It is a good idea for all drivers to take a little time to educate themselves about various speed measurement technologies and such. While I'd say the majority of police departments use their equipment right and the tickets are legit, they aren't always. If you get nailed with a bogus ticket, you don't necessarily need GPS to fight it. Tell the department you want the calibration records for the gun in question, find out if it was in pop mode, etc, etc. If they screwed up, let the judge know and they'll most likely drop the ticket.
To this date, no hard factual science has proven that speed cameras have saved lives or reduces accidents.
Yeah, I've noticed that the Brits found no use at all for their systems - it's not like tracking down the speeders in central London has saved lives. I guess that the Lancet was just not hard or factual enough a source...http://www.thelancet.com/newlancet
If your GPS time was off by even one second, your position would be off by about 300km -- give or take depending on satellite geometry -- there's no way to separate the two.
Sure there is. The GPS clock system is independent of our common business-day clock. GPS does not incorporate time zones, does not incorporate daylight savings time adjustments, does not incorporate leap years or leap days or leap seconds or anything else. It is not tied to any earth time system. The GPS network simply counts its own seconds, independent of our earthly wall-clock time conventions.
The GPS unit likely has an independent clock circuit so that you can have a clock even when you are not receiving any GPS signals. And if it is running off of satellite time, it would have to have some stored translation factor to convert the satellite time to an earth-clock time, to account for time zones and daylight savings time and other adjustments, and to account for the fact that the satellite time *does* drift out of sync with official earth time systems. In fact due to leap seconds and whatnot, GPS time has drifted 14 seconds out of sync with GMT / UTC Coordinated Universal Time.
The fact that it was even physically possible for him to manually set the clock proves that the satellite time was not being directly displayed on the clock, that there is either an independent internal clock and/or some stored translation factor to convert the GPS network's internal clock system into whatever "common local time" you want displayed on the user-clock. None of this would would be used in the GPS position calculations.

Considering that The Lancet recently got caught with their hand in the cookie jar making up bogus statistics about the number of war dead in Iraq at the behest of George Soros, I too have a hard time accepting anything said in The Lancet (http://www.liveleak.com/view?i=7b2_1199991668) as factual. They really have pooped in their own nest when it comes to integrity.
No mod points, no meta-moderating/Firehose/all the other free work Slashdot wants me to do.
I think that if I gave them a car, that would be just enough rope to hang themselves.
... then they'd either accept the car WITH lojack, or not accept the car. Either way, I offered.
... and watch them go crazy trying to find the second, non-existant one....
If I gave them a lojacked car
and if my kids are smart, they'd find a way around being tracked, and I'd congratulate them for it. Then I'd tell them I actually had two tracking devices in it (which I wouldn't)
Sure takes the fun out of being a teen tho....thank God my folks didn't have this when I was young. I had a blast....but, didn't get into trouble, made my grades....worked etc. But, I ran around...partied...didn't get DWI's (hell, I got pulled over once half tanked, but, was close to home and the cop let me drive home warning I'd go to jail if he saw me out again that night, man, you'd not see THAT happen again these days).
There are only 'consequences' of actions if you do something wrong or get caught. Kids have to make mistakes and take chances in order to grow. If you parents are so over protective, how are you going to learn....and being young is the time to be a little reckless and have fun. You get to be 'resposible' and adult acting soon enough...
Light travels faster than sound. This is why some people appear bright until you hear them speak.........
Completely Wrong. ALL GPS devices calculate your position in three dimensions. The military uses them to fly missiles. They could not do this if they were as poorly designed as you think. While it is true that the LCD DISPLAY only show your horizontal position, the machine knows your exact location in all three dimensions (plus time) and uses those numbers calculate your speed etc. You need to realize the difference between what the machine knows and what it tells you. It almost always knows a LOT more than it shows.

And well you shouldn't! You endangered everybody you encountered on the road that night. In my opinion, the cop was irresponsible to let you go. If getting pulled over for DWI vas a virtual guarantee of a visit to jail (assuming that you actually fail the test, of course) then maybe fewer people would be so casual about operating complicated and deadly machinery while under the influence of mind-numbing drugs.
If you mod me Overrated, you are admitting that you have no penis.
You claim that many people can drive just fine at .08 BAC, do you have any cites or evidence for this? I ask simply because I don't believe it. I know that there are many people who think that they can drive just fine at .08 BAC (or some other level), but this is mainly because moderate amounts of alcohol tend to mess with your perception in such a way that you feel like you're doing the same as before, when in fact your reactions and judgement are significantly degraded. People who believe that they experience no impairment after "just a couple of beers" are, from what I've seen, just plain wrong about it.
Your rant against the police is very strange to me. You're taking charge of a large, dangerous machine, one which is dangerous not only to yourself but to anyone who comes near you. You owe it to yourself and to society to be in good mental condition when you do this.
I don't drink and drive, period. If I'm driving somewhere within the next couple of hours I do not drink. If I want to have a beer with dinner, I make sure that I can stay in the area for a while afterwards, or I go someplace within walking distance, or I have somebody else drive. I tried driving with "just one beer" a couple of times. I felt fine, with no effect on my driving. Thinking about it afterwards I realized that my reactions were significantly slower, and my judgement was much worse. So I never did it again.
I consider the legal limit to be quite a bit higher than it should be. I'm a pilot, and the FAA has very strict limits on alcohol. The BAC limit is .04, which is basically any detectable alcohol in the blood. In addition to this limit, they have a strict limit (hard to enforce, of course) that you may not drink any alcohol in the eight hours before you take the controls of an aircraft. This is vastly more strict than any automobile laws I'm aware of. But guess what, I've never heard any pilot complain about the rules.
The trick to avoiding police action is quite simple: if you drink, do not drive. They won't be able to convict you of anything if there isn't any alcohol in your blood. And you shouldn't have any alcohol in your blood while operating a car, no matter what the law allows.
I agree that the law should be based on a much broader definition of impairment, rather than being so specific to alcohol. But I think the standard of impairment should be much lower than it is as well.
