Track a Cell Phone Using GPS
From LoveToKnow Cellphones
In emergency situations, it's good to know it is possible to track a cell phone using GPS. What this means is that when someone calls 911, but becomes unable to tell the operator his or her location, the 911 attendant can then team up with the mobile service provider to find the caller's location within approximately 100 meters. But what about other applications? And is it legal to track someone based on their cell phone signal?
Track a Cell Phone Using GPS
It is possible to track a cell phone using GPS technology, because at any time, a mobile phone is sending out a signal. This happens whether there is a voice call or not, meaning that even in standby mode, a signal is being sent out by the cell phone's "radio." This is true of both CDMA and GSM-based cell phones.
In order to determine the location of a cell phone (and thus, the person attached to it), technicians can gather data from three nearby cell phone towers. By comparing the relative strength of the signal between these towers in the service area and placing these figures into a complex algorithm, they are able to find the location within 100 meters or so. This comes in very handy for emergency situations, because a person may be in danger.
Verizon VZ Navigator Service
Verizon Wireless offers a GPS-like navigation service on many of their cell phones. Call the Verizon VZ Navigator Service, it is not true GPS, because the mobile phones are typically not equipped with GPS receivers. Instead, this turn-by-turn navigation Java application finds your location based on a similar triangulation method to the one described above. As such, it is not necessarily "smart" enough to know your precise location at all times and must constantly update itself by connecting to the cell phone towers.
Because the service is from the handset's point of view, it is not "tracking" in the traditional sense, but you can see the potential of such a possibility based on the technology that is already in place. The Verizon VZ Navigator service basically demonstrates what can be done without the need for an actual |GPS receiver.
Sprint-Nextel GPS Cell Phones
While not quite available for Sprint PCS phones, there are a few handsets in the Nextel lineup that come equipped with full-fledged GPS. These are mostly the iDEN-based Motorola cell phones and they are designed for business people and folks who work outdoors, particularly in industrial areas or rugged terrain. By launching the equipped GPS application, users can find their current location and navigate themselves appropriately. Eventually, this sort of functionality should extend to the entire Sprint-Nextel family.
At this time, there is no direct service that allows for remote tracking of individuals via this service. Instead, it is largely restricted for emergency personnel if a cell phone must be tracked externally. This is in line with privacy legislation.
Boost Mobile: Where You At?
Boost Mobile, an MVNO (mobile virtual network operator) that runs off of the Sprint-Nextel network, has a GPS-based service that allows friends to track one another's whereabouts. This is an opt-in service, so you shouldn't necessarily by afraid that a random person could be finding out where you are. At the same time, the possibility is there, and just as people can hack into computer networks, it is also possible that a hacker may infiltrate a cellular network.
Legal Ramifications
It is illegal to track a person without the proper legal authority, and as such, unless you have a justifiable reason for doing so, you probably shouldn't attempt to track a cell phone using GPS without the person's explicit permission. The exception to this, as mentioned above, pertains to emergency personnel, because by dialing 911 on the cell phone, the user has effectively granted permission to the emergency response team to track them accordingly.
Comments
Sbarr: One strategy that you can try taking is to simply change your cell phone and/or your cell phone number. If the person does not know what phone you are using or what number you have, they fundamentally cannot track the location of the handset. If the cell phone is turned off, it obviously does not give out any signals, and as such, will not be traceable. If your phone does not have GPS, it is still *possible* to track you by way of signal triangulation. This isn't as accurate as GPS, but it does provide some information.
-- Contributed by: MichaelKwanI have a question. I have a close female friend who has an obsessive stalker and he has managed to hack her phone so that he could track her exact location at all times. He also has my cell phone number along with some other friends of hers. He got all of our numbers when he stole her cell phone from her and gave it back the next day.
My female friend has Verizon, this stalker guy has Nextel, and I have Cingular. I there anything we can do about this?
Also, is it true that if you keep your cell phone OFF, they cant use the GPS to track you?
Also, if your cell doesnt have GPS, can they still track you?
Your response or suggestions would be greatly appreciated.
