You might want to think twice about leaving it on. The US District Court in Mass just passed a law allowing the authorities to get a historical record of your movements via your cel phone if it has "relevance to an ongoing investigation."

CLICKY

Weak, super weak!

One could pop the battery AND sim card out, then hold the power button to drain any last power...

of course shutting off the phone totally might be a tip-off also...

One step away from being miro-chipped and barcoded.

How accurately could one's movement be tracked such as county wide, city wide, specific neighborhood you were located?

According to this...50 to 500 meters.

All phones have GPS now. plus with triangulation they can get to about 15 meters of accuracy in some areas.

if you're that paranoid, simply turning it off will do.

if it is on, your location will be known within a 50m radius.

i may or may not have done this in conjunction with certain gov. agencies.

look out! you're being watched! hahahahahaa.

Does signal strength of the triangulating diminish the accuracy? Also, provider towers, etc? When I am in some cities, I do not get very good reception at all? I thought the GPS alone was nearly dead accurate.

Oh no it is much worse than you all thought, they can track your phone even while it is off!! You actually have to take the battery out here is a news report on just this very subject.

I had a situation where I had to investigate 40 stolen cell phones, that were stolen from the cell phone company (the carrier who owns the cell towers).

I saw the super-secret maps and cell logs - that normally you can't get without government action - that were available to the cell tower owners. I was given a spreadsheet that logged each call by tower, number called, time of call, call duration, and all the handoffs to new towers.

The best they could do is report which tower was "hit" with the cell phone calls, and the mode (analog/digital) of the phone at the start of the call. This gave a donut shaped "high", "medium" and "low" probability zone around the cell tower - and using handoffs you could assume the person was between the two towers. Using that, plus the phone number called, linked the thief's house to the phone based upon the stupid person calling their own house.

To turn on the GPS for non-911 calls, it is an option inside the phone - or at least the phones I have used. Normally not logged, but sent to the receiving party - for an example - the nextel phones that have GPS will send text messages to the owner's server for tracking realtime employees.

There is a difference between historical data logged versus real time tracking. I have no doubt they could see exactly where a phone is at the current time... Where it was yesterday is a farther stretch, especially with accuracy, unless calls were made.

Why?

Verizon has 56 million subscribers. If they polled the network every 10 seconds and recorded the location of each subscriber, the database would have 176,601,600,000,000 entries per year. This amount of dataload (that is trillions, right) would be insanely expensive to store, and require insane amount of processing power to process.

I am not worried about tracking unless I make a call from the object, and even then, it would be hard to prove anything other than the fact I was somewhere in the region.

But that is my phone, with my settings... Your phone may be different.

hahaha! that is absolute bullshit. but believe what you want. fuckin' propaganda.

if all you're doing is base jumping and trespassing, you really don't need to worry about being tracked by the FBI, i assure you.

I am not woried about being tracked by anyone except my X-girlfriends they are the dangerous ones

that however, IS a serious threat.

I take my home phone. Land-lines are more reliable than cell phones in remote areas.

well if the police has nothing else to do than figure out who the person who jumps this object is,oh well then good on them.. ill leave my phone on anyday..
best advice for the cops..
If you know im a basejumper and follow my pathen becourse catching basejumpers is on your top 3 list then simply stand by the object and get me there..
paranoied fuckers!!!

a much larger concern is the smell of my shit after a long night of drinking. seriously, if you are worried about the government tracking you because you are BASE jumping, you should put the crack pipe down and get some professional help. Right away, if not sooner.

well a cell phone helped locate a dead hunter...

Technology is getting better....

What about the tower owners? What about other third parties? NPS? It's not like cell phone tracking is some secret voodoo only allowed to the selected few. Have a look at Osmocom e.g. And SDR are getting better and cheaper by the day.

Both second and third generation protocols contains flaws in them allowing anyone to use cell phones as triggers for proximity alarm systems. Methods for identification of the device exists as well.

When i say anyone, I mean anyone. The law might not agree with that depending on your gouvernment though.

I jumped with a cellphone twice. Mostly I use radios. Cheaper and more reliable in the long jump.
But, as being a safety minded dude, It is very efficient if you are jumping with cellphones and NOT radios, to let the others on your jump know the number. Emergency services are way cool with speaking to the injured about to be rescued. Also the cellphone can ring and serve as locator when you are unconscious or...

Safety is important, I agree. But if a jumper carries an active phone in some way associated with him, there's technical solutions out there to track his movements. And, since BASE jumping has a dependency on physical objects, proximity alarm systems identifying cell phones are bad. While I'm not aware of any such products on the market, I've seen some pretty cool homebrewn stuff.

Someone said that it's just too much data. But you will only need data from one or a few cells if you wanted to track people going to a cliff in the dead of night. Hell, you wouldn't even need cell data if you just want a limited area inside a cell covered.

There's other (and better) safety systems out there than carrying an active cellphone.

I'm laughing so hard I'm crying!!!!

HAHA!!! Good one Bro!

However, there is the technology to do this, as a female friend of mine found out the hard way. Her husband suspected something wasn't right, tracked her phone and,.....well he was right

Not that much data if it is stored here .

Sorry, I forgot about them ill-eagle jumps. I am hangin in Europe. Are you guys still dying to not get busted? That is so last century...:-) The NPS should get a clue.

Actually, I am also in Europe. I was born here. Though the particular area where I reside lacks any open sites, so you either make do with what you've got or you'll need to take a vacation to go jumping. I would love to be able to leave my house for a weekend of hiking and jumping openly, but then I would have to depart from my native land and seek my fortune elsewhere, as there is no such place around. In the meantime, there's a few places where I can jump, but if people found out, they would try and stop it. So it's important to take certain measures to prevent this.

Also, the legal sites in our world today might not always stay legal. Would you respect such a ban?

The NPS was just an example, I could've mentioned some local parties instead, but then less people could relate to that.

Of course I would respect a ban
I would get off my asss (not accusing you of anything, just sayin) and do it the democratic way. It works in other countries. I and others have worked with the guv to keep great sites open.

I want to say that for some, the "Get away" factor was a driving force. I cannot say that I didnt get this at times. But it didnt become my driving force. No probs with this.

Just finish the equation. Is it worth it?

Tower emulators are monitoring you....
