How to Track, Trace and Monitor Cellphones – GPS Technology TopicsUnder FCC regulations for emergencies (e911) GPS information, is transmitted only during an emergency 911 call. Smartphones could possibly have GPS and also the device might “know” exactlywhere it is, but it is unable to “tell” anyone else where it is, unless connected with a cellular network. To adhere to Federal Communications Commission rules, cell phone companies must be in a position to furnish authorities with cell phone latitude and longitude to an accuracy of 50 to 300 meters. Cell Tower Triangulation doesn’t always meet this requirement. By way of evaluation, commercially accessible GPS systems can certainly obtain accuracy down to less than 10 meters. This varies according to a lot of factors, as GPS signals are often quite weak and are impacted by numerous environmental factors. With Mobile Location Services (MLS), the GSM cell network provider utilizes triangulation techniques to compute the location of the cell phone, its accuracy is proven to be much worse than that of GPS. MLS is further impacted by the same issues as GPS in the sense of the interference affecting signal strength and the density of GSM towers to assist in the triangulation calculation. In rural areas location accuracy may be off as much as a mile. GPS receivers, whether in a cell phone, or a dedicated GPS tracking device, calculate location through process of precisely timing the signals transferred by GPS satellites. This critical information provides the moment the message was transmitted, specific orbital information (formally called the ephemeris), plus the basic system status and projected orbits of all GPS satellites (formally called the almanac). GPS receivers often take longer to become ready to navigate after it’s turned on because it must acquire some basic information in addition to finding GPS satellite signals. This slow start can be caused if the GPS mobile phone has been turned off for days or weeks, or has been moved a far distance while turned off. The GPS must update its almanac and ephemeris data and store it in memory. The GPS almanac is a set of data that every GPS satellite transmits. When a GPS receiver has current almanac data in memory, it can capture signals and determine initial position more quickly.

In order to trace a cell phone involves various key ways of formulating smartphone location. GPS (Global Positioning System/Satellites), Triangulation, and CellID. All these technologies convert smartphones into mobile tracking devices. These types of systems can be seen as Network Based, Handset Based or possibly a Hybrid method. GPS location is Handset based because it needs programs placed on the cell phone combined with GPS hardware. Triangulation and CellID are Network Based since they use the equipment and information from the wireless provider. Hybrid techniques bring together techniques to generate best use of available information and to help make perform faster.
