Do you actually know where your Staff or Children are? – GPS Technology Info To abide by Federal Communications Commission rules, cellular phone companies must be able to give authorities with device latitude and longitude to an precision of 50 to 300 meters. Cell Tower Triangulation will not always meet this requirement. By way of comparison, commercially available GPS modules can obtain accuracy down to less than 10 meters. This is dependent on numerous factors, as GPS signals are often rather weak and are affected by numerous environmental factors. With Mobile Location Services (MLS), the GSM cellular network provider utilizes triangulation techniques to compute the position of the cell phone, its accuracy is proven to be much worse than that of GPS. MLS is also affected 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 effort. In rural areas location accuracy may be off as much as a mile. GPS receivers, no matter whether inside a phone, or a specific Portable gps tracking device, calculate location through precisely timing the signals transferred by GPS satellites. This critical information includes the moment the message was transmitted, precise orbital information (formally referred to as the ephemeris), as well as the general system health and rough orbits of all GPS satellites (technically called the almanac). GPS receivers often take a long time to become ready to navigate after it’s turned on because it must acquire some basic information in addition to capturing GPS satellite signals. This delay is sometimes caused when the GPS cell phone has been unused for days or weeks, or has been moved a significant distance while unused. 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 satellite signals and determine initial location more quickly.

For you to track a cell phone involves various principal approaches of establishing cell phone position. GPS (Global Positioning System/Satellites), Triangulation, and CellID. Every one of these technologies convert smartphones into mobile tracking devices. These kinds of systems can be considered Network Based, Handset Based or possibly a Hybrid technique. GPS location is Handset based as it calls for software programs installed on the mobile phone together with GPS hardware. Triangulation and CellID are Network Based because they make use of the equipment and information from the wireless provider. Hybrid systems integrate techniques to make best use of available information and to help make perform faster.
