How To do Mobile Tracking

Solutions Engineered for Emergency Response May Be Used for Keeping Track of Your Kids. Cell tracking, cell phone GPS and mobile phone tracking software are unquestionably getting a lot of interest from potential customers, phone businesses and program makers. The most recent mobiles integrate GPS position attributes to track telephone location.

GPS receivers, no matter if inside a cell phone, or simply a specific Portable gps tracking device, calculate position by way of accurately timing the signals sent by GPS satellites. This data contains the time the message was transmitted, exact orbital data (formally called the ephemeris), along with the basic system condition and calculated orbits of all GPS satellites (technically referred to as the almanac). GPS receivers sometimes take a long time to become ready to navigate after being turned on because it must acquire some basic information in addition to finding GPS satellite signals. This slow start is sometimes caused when the GPS mobile phone has been turned off for days or weeks, or has been moved a far distance while turned off for. 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 satellite signals and calculate initial location more quickly.

GPS Hot Start refers to whenever the GPS enabled handset keeps its last calculated location, the satellites that were in range before, together with the almanac data in memory, and attempts to obtain the same satellites and determine a fresh position based upon the previous data. This is usually 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 refers to when the GPS enabled handset keeps its last calculated location, and almanac used, but not which satellites were in range. It performs a reset and attempts to connect to satellite signals and calculates a brand new location. The GPS receiver narrows the choice of which satellites toseek since it saved its last known location and also the almanac data helps identify which satellites are within view. The Warm Start is going to take longer than the Hot Start although not as long as a Cold Start. With GPS Cold Start, the device deletes all the previous information, and tries to find satellites and attain a GPS lock. This takes the longest since there is no known reference data. The GPS enabled smartphone receiver has to try to lock onto a satellite signal from any accessible satellites.

To be able to have better GPS lock times cellphone manufacturers and wireless providers introduced Assisted GPS technology. It downloads the ephemeris and helps triangulate the smartphone basic position. GPS Receivers can get a faster lock at the expense of a few kilobytes of data transmission. Assisted GPS, also known as A-GPS or AGPS, helps the performance of standard GPS in cell phones connected to the cell network. In the United States Sprint, Nextel, Verizon Wireless, and Alltel all use AGPS. This is a method of utilizing the cell network to accelerate acquisition of GPS satellites.

A-GPS assists location tracking performance of mobile phones (and also other connected devices) in two ways:

One way will be assisting to acquire a more rapid “time to first fix” (TTFF). Assisted GPS acquires and archives information concerning satellite location utilizing the cell network so the position data does not require to be downloaded from the the satellite.

The next approach is by helping position smartphones when GPS signals are weak or impeded. Due to the fact GPS satellite signals may be impeded by tall buildings, and do not go through building interiors well Assisted GPS employs proximity to cellular towers to compute location when GPS signals are not accessible.

When satellite signals are not obtainable, or accuracy is less important than life of the battery, applying Cell-ID is a viable substitute to GPS mobile phone tracking. The location of the mobile phone can be calculated by the cell network cell id, that identifies the cell tower the cell phone is using. By having the location of this tower, you’ll be able to know roughly the spot where the device might be. But, a tower can cover a huge area, from a couple of hundred meters, in higher populationdensity areas, to a few miles in lower density zones. For this reason location CellID accuracy is less than than GPS accuracy. Even so location via CellID still delivers a very viable alternative.

Another method of determining handset location is Triangulation or Mobile Location Services (MLS). Cell Tower Triangulation makes use of signal analysis data to determine the time it takes signals traveling from the smartphone to at least three cell towers to estimate position.
