Cell Phone Tracking Basics

GPS Technological Topics

Under FCC regulations for emergencies (e911) GPS data, is sent only during an emergency 911 call. Mobile phones could have GPS and the device may “know” exactlywhere it is, nevertheless it really is not able to “tell” anyone else where it is, until linked to a wireless network. To help adhere to Federal Communications Commission guidelines, cell phone companies have to be in a position to give authorities with handset latitude and longitude to an precision of 50 to 300 meters. Cell Tower Triangulation fails to always meet this requirement. By way of evaluation, commercially available GPS modules will be able to realize accuracy down to less than 10 meters. This hinges on several factors, as GPS signals are often rather weak and they are influenced by many factors. With Mobile Location Services (MLS), the GSM cell network provider uses triangulation techniques to determine the location of the cell phone, its accuracy is proven to be much worse than that of GPS. MLS is also impacted by the same issues as GPS in the sense of the barriers impeding signal quality and the density of GSM towers to assist in the triangulation effort. In remote areas location accuracy may be off as much as a mile. GPS receivers, regardless of whether in a smart phone, or simply a dedicated Portable gps tracking device, calculate position by way of precisely timing the signals passed on by GPS satellites. This critical information contains the moment the message was transmitted, exact orbital data (formally referenced as the ephemeris), and also the basic system condition and projected orbits of all GPS satellites (technically called the almanac). GPS receivers sometimes take a long time to become ready to use after it’s turned on because it must acquire some basic information in addition to finding GPS satellite signals. This delay is sometimes caused when the GPS device has been turned off for days or weeks, or has been moved a significant 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 acquire signals and calculate initial location more quickly.
