Cell tracking, mobile GPS and cell phone tracking programs are really drawing curiosity from individuals, cellphone companies and application designers. The most current cell phones have GPS location attributes to track cellphone position.

In order to conform to Federal Communications Commission rules, cellular phone companies are required to be in a position to furnish authorities with handset latitude and longitude to an accuracy of 50 to 300 meters. Cell Tower Triangulation doesn’t always satisfy this requirement. By way of evaluation, commercially available GPS systems can achieve accuracy down to less than 10 meters. This is determined by many factors, as GPS signals tend to be really weak and are influenced by many variables. With Mobile Location Services (MLS), the GSM cellular network provider utilizes triangulation techniques to try to pinpoint the location of the cell phone, its accuracy is proven to be much worse than that of GPS. MLS is further affected by factors similar to GPS in the sense of the interference impeding signal quality and the density of GSM towers to help in the triangulation effort. In rural areas position accuracy may be off as much as a mile.

GPS Hot Start describes whenever the GPS enabled device retains its last identified location, the satellites that were in view before, and also the almanac data in memory, and tries to connect to the same satellites and calculate a brand new location based upon the previous information. This is usually the quickest GPS lock but Hot Start only works if the phone is generally in the same location as when the GPS was last turned off. GPS Warm Start means when the GPS enabled smartphone recalls its last known location, and almanac used, but not which satellites were in view. It performs a reset and attempts to obtain satellite signals and computes a new position. The GPS receiver has a general idea of which satellites toseek since it saved its last known position and the almanac data helps identify which satellites are visible in the sky. The Warm Start is going to take more time than the Hot Start but not as long as a Cold Start. With GPS Cold Start, the device dumps all the previous data, and tries to locate sa

tellites and obtain a GPS lock. This will take more time because there is no known reference information. The GPS enabled handset receiver must try to lock onto a satellite transmission from any available satellites.

In order to have better GPS lock times mobile phone manufacturers and telco operators introduced Assisted GPS technology. This downloads the ephemeris helping triangulate the cell phone general position. GPS Receivers can get a quicker lock at the expense of a few kilobytes of data transmission. Assisted GPS, also known as A-GPS or AGPS, improves the performance of normal GPS in smartphones connected to the cell network. In America Sprint, Nextel, Verizon Wireless, and Alltel all use AGPS. Which is a method of using the cellular network to accelerate finding of GPS satellites.

A-GPS assists location tracking functions of smartphones (along with other related devices) in two ways:

The first way is by assisting to secure a faster “time to first fix” (TTFF). A-GPS acquires and stores data about satellite location using the cellular network so the position details does not need to be downloaded from the the satellite.

The other approach is by helping locate handsets when GPS signals are weak or impeded. Because GPS satellite signals may be interfered with by tall buildings, and do not go through building interiors well Assisted GPS employs distance to cellular towers to calculate position when GPS signals are not available.

In the event that satellite signals are not accessible, or accuracy is less important than life of the battery, applying Cell-ID is a viable substitute to GPS smartphone location. The location of the smartphone might be approximated by the cellular network cell id, which identifies the cell tower the phone is using. By understanding the position of the tower, you may know roughly the spot where the handset might be. But, a tower can cover a large area, from a few hundred meters, in higher populationdensity zones, to several kilometers in lower density regions. For this reason location CellID accuracy is lower than GPS accuracy. Nonetheless location from CellID still supplies a really useful substitute.

Another way of calculating cell phone location is Triangulation or Mobile Location Services (MLS). Cell Tower Triangulation employs signal analysis data to compute the time it takes signals to travel from your telephone to no less than 3 cell towers to determine position.
