Technology Formulated for Emergency Response Can Be Utilised for Tracking Your Teenagers. Cell tracking, mobile GPS and cell phone tracking tools are drawing focus from consumers, cellular phone companies and program makers. The most up-to-date mobile phones feature GPS locator attributes to track cell phone location.
In order to conform to Federal Communications Commission guidelines, cell phone companies are required to be in a position to deliver authorities with mobile phone latitude and longitude to an precision of 50 to 300 meters. Cell Tower Triangulation does not always satisfy this requirement. For comparison, commercially available GPS systems can certainly achieve precision down to 3-10m. This varies according to numerous factors, as GPS signals tend to be particularly weak and they are impacted by numerous environmental factors. With Mobile Location Services (MLS), the GSM cellular network provider utilizes triangulation algorithms to compute the location of the cell phone, its accuracy is proven to be less than than that of GPS. MLS is further impacted by factors similar to GPS in the sense of the interference affecting signal strength and the density of GSM towers to assist in the triangulation effort. In remote areas position accuracy may be off as much as a mile.
GPS Hot Start is the term for whenever the GPS enabled cell phone keeps its last known location, the satellites which were in range at the time, as well as the almanac information in memory, and tries to connect to the same satellites and compute a new position based upon the previous information. This is almost always the quickest GPS lock but Hot Start only works if the phone is generally in the same location as when the GPS was last switched off. GPS Warm Start describes when the GPS enabled handset remembers its last known location, and almanac used, but not which satellites were in view. It resets and makes an attempt to obtain satellite signals and computes a whole new location. The GPS receiver has a general idea of which satellites toseek because it saved its last known location and also the almanac data helps identify which satellites are within view. The Warm Start will take longer compared to Hot Start but not as long as a Cold Start. With GPS Cold Start, the device deletes all the previous information, and attempts to locate satellites and achieve a GPS lock. This normally takes the longest since there is no known reference information. The GPS enabled mobile phone receiver must attempt to lock onto a satellite signal from any accessible satellites.
As a way to have improved GPS lock times cellular phone manufacturers and network operators designed Assisted GPS technology. It downloads the ephemeris helping triangulate the handset general position. GPS Receivers will get a quicker lock in exchange for a few kilobytes of data transmission. Assisted GPS, also called A-GPS or AGPS, boosts the performance of normal GPS in smartphones connected to the cell network. In the United States Sprint, Nextel, Verizon Wireless, and Alltel all use AGPS. Which is a method of using the cell network to accelerate acquisition of GPS satellites.
A-GPS improves location tracking functions of mobile phones (as well as other related devices) in two ways:
One way will be helping to secure a more rapid “time to first fix” (TTFF). A-GPS receives and archives information in relation to the location of satellites utilizing the cell network so the coordinates information does not need to be downloaded from the the satellite.
The next technique is by assisting locate handsets when GPS signals are weak or blocked. Because GPS satellite signals may be impeded by tall buildings, and do not penetrate building interiors well Assisted GPS utilizes proximity to cellular towers to approximate location when GPS signals are not readily available.
When satellite signals are not readily available, or precision is less important than life of the battery, employing Cell-ID is a viable substitute to GPS mobile phone location. The location of the handset can be calculated by the cellular network cell id, which identifies the cell tower the cellphone is using. By knowing the position of this tower, you’ll be able to know roughly where the device is. Still, a tower can cover a huge area, from a couple of hundred meters, in high populationdensity regions, to a few kilometers in lower density zones. This is why location CellID precision is lower than GPS accuracy. Having said that tracking using CellID still supplies quite a handy substitute.
Another method of formulating mobile phone position is Triangulation or Mobile Location Services (MLS). Cell Tower Triangulation makes use of signal analysis data to compute the time it takes signals traveling from your mobile phone to no less than three cell towers to estimate location.
