Solutions Launched for Emergency Response Can Be Employed for Tracking Your Children. GPS tracking, mobile GPS and cell phone tracker applications are gaining notice from potential customers, cellular telephone businesses and program creators. The up-to-date smartphones provide GPS locator functions to track smartphone location.
In order to adhere to Federal Communications Commission guidelines, cellular phone companies have to be in a position to supply authorities with handset latitude and longitude to an precision of 50 to 300 meters. Cell Tower Triangulation does not always meet this requirement. By way of evaluation, commercially accessible GPS systems are able to acquire precision down to 3-10m. This varies according to several factors, as GPS signals tend to be quite weak and they are influenced by many environmental factors. With Mobile Location Services (MLS), the GSM cellular network provider utilizes triangulation techniques to compute the position of the handset, its accuracy is proven to be less than than that of GPS. MLS is further affected by the same issues as GPS in the sense of the barriers impeding signal strength 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 Hot Start is the term for whenever the GPS enabled device recalls its last known position, the satellites that were in range before, together with the almanac information in memory, and makes an attempt to lock onto the same satellites and compute a fresh position based upon the previous information. This is almost always the quickest GPS lock but Hot Start only works if the phone is in the same general area as when the GPS was last switched off. GPS Warm Start is the term for when the GPS enabled device recalls its last known location, and almanac used, but not which satellites were in range. It resets and tries to connect to satellite signals and computes a whole new position. The GPS receiver narrows the choice of which satellites toseek because it kept its last known location and the almanac data helps identify which satellites are in range. The Warm Start will take longer than the Hot Start although not as long as a Cold Start. With GPS Cold Start, the device deletes all the previous data, and tries to find satellites and attain a GPS lock. This takes longer than other methods because there is no known reference data. The GPS enabled cell phone receiver has to try to lock onto a satellite signal from any available satellites.
As a way to get better GPS lock times cellular phone manufacturers and wireless providers developed Assisted GPS technology. It downloads the ephemeris helping triangulate the mobile phone basic location. GPS Receivers will get a faster lock in exchange for a few kilobytes of data transmission. Assisted GPS, often known as A-GPS or AGPS, helps the performance of normal GPS in devices connected to the cellular network. In America Sprint, Nextel, Verizon Wireless, and Alltel all use A-GPS. Which is a method of utilizing the cellular network to accelerate finding of GPS satellites.
A-GPS improves location tracking performance of cell phones (as well as other related devices) in a couple of ways:
The first method will be assisting to obtain a more rapid “time to first fix” (TTFF). A-GPS receives and stores data regarding satellite location via the cellular network and so the location data does not need to be downloaded from the the satellite.
A subsequent technique is by assisting position mobile phones when GPS signals are weak or impeded. Because GPS satellite signals may be interfered with by tall buildings, and do not penetrate building interiors well AGPS employs distance to cellular towers to compute position when GPS signals are not available.
When satellite signals are not obtainable, or precision is less important than battery life, applying Cell-ID is a useful substitute to GPS smartphone tracking. The position of the smartphone can be calculated by the cellular network cell id, which determines the cell tower the mobile phone is connected to. By having the position of the tower, you’ll be able to know roughly where the device might be. Still, a tower can cover an enormous area, from a few hundred meters, in higher populationdensity regions, to a few miles in lower density regions. For this reason location CellID accuracy is lower than GPS accuracy. Nonetheless monitoring via CellID still gives you a truly handy substitute.
Another way of calculating device location is Triangulation or Mobile Location Services (MLS). Cell Tower Triangulation employs signal analysis data to determine the time it takes signals traveling from your smartphone to a minimum of 3 cell towers to determine position.
