GPS tracking is the application of a worldwide satellite navigation system, resting in the planet's orbit, that exchanges data with a digital device, so as to trace the position of an individual or object on Earth's surface. This kind of navigation system supplies a nonstop means to tracking, despite seasonal conditions, provided that there's an unhindered sightline between the satellites and the object they're following. The job necessitates a number of at least four satellites to evaluate the location of the device. They're mounted in medium orbit around our planet and are able to verify location with a lot of dependability.

GPS tracking systems are generally utilized for vehicle tracking, that can be fundamental in case of an accident. The position information can be preserved and passed along to a database using the Internet. In day to day life, nonetheless, GPS systems attached to cars are utilized to assist drivers throughout area maps, by returning a live feed on their location, together with advice for workable paths to a targeted destination.

GPS tracking devices can be grouped into three classes: data loggers, data pushers and data pullers. Data loggers are GPS units that just register the location of the device, every once in awhile. The information is saved on a storage device and may eventually be downloaded to a workstation for extensive study.

Data pushers are the most broadly used sort of GPS equipment, and they can be employed to monitor people and goods, or as vehicle tracking systems. They operate by simply "pushing" the position information (in addition tovarious other significant details, including elevation and speed) into a server which can gather and process it.

In recent years, GPS devices are starting to be integrated into high-end mobile phones, and tracking applications applications may be bought or acquired for free, as open source software. Data pushers have numerous uses - in law enforcement, to track offenders who are on bail; in sports, as a means to monitor races; in surveillance and espionage; and to aid with the care of the elderly. GPS trackers may also be used to monitor wild animals and study many of their activities, such as migration and breeding patterns.

Data pullers would be the literal opposite of data pushers, and they are utilized to directly "pull" information concerning position. They represent a less frequent sort of GPS unit and are in some cases utilized to monitor goods or cargo, that don't call for steady data feed.
