What is GPS tracking and how does it work?

GPS tracking is defined as the utilization of a worldwide satellite navigation system, situated in the planet's orbit, that exchanges information with a digital device, as a way to trace the position of an individual or object on Earth's surface. This sort of navigation system offers a steady method of tracking, regardless of seasonal conditions, so long as there's an unhindered sightline between the satellites and the object they're monitoring. The procedure entails the application of at least four satellites to compute the location of the device. They're placed in medium orbit around our planet and have the ability to establish location with a great deal of consistency.

GPS systems are usually used for vehicle tracking, which can be crucial in the event of an emergency. The location data may be recorded and transmitted to a database via the Internet. In every day life, however, GPS systems mounted on vehicles are used to coordinate drivers across area maps, by delivering a live feed on their position, coupled with directions for possible routes to a 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 widespread type of GPS device, and they can be used to track individuals and assets, or as vehicle tracking systems. They work by essentially "pushing" the location data (together withother relevant information, such as altitude and speed) to a server that can store and analyze 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 are the exact opposite of data pushers, and are used to literally "pull" data regarding location. They are a less common type of GPS device and are sometimes used to track freights or containers, which do not require a regular data feed.
