Regarded as one of the greatest innovation that man has come up with, the GPS (Global Positioning System) tracking technology has bring about efficiency and effectiveness in several industries these days. GPS tracking technology is a navigational system that lets you track the location, speed and course of the GPS receiving device.

Developed by the Defense Department for military purposes in the United States, GPS tracking technology was officially called as NAVSTAR GPS. GPS tracking technology is widely utilized as navigation assistance worldwide. Other than that, GPS tracking technology is also a valuable tool for mapping, geographical surveying, commerce and other scientific exploits.

The GPS tracking operation works by calculating the position of the GPS receiver. The location of the GPS receiver is determined by assessing the distance between the receiving device and three (or sometimes more than three) GPS satellites.  The time delay between the broadcast and receiving GPS signal gives the distance to each GPS satellite. The transmission and receiving signal also contain information of the current position of each satellite. A minimum of three GPS satellites are required in order to accurately determine the location of the GPS receiver.

GPS tracking technology has countless number of applications. Most of the automobile these days are equipped with GPS tracking technology. They are used for tracking purposes. Other than that, GPS technology is also used as part of the security system of the vehicle. In the event that the vehicle gets stolen, the location of the vehicle can be determined by tracking it via GPS. The current location of the vehicle can be determined even if it the vehicle is moving.

Because of the advancement of the GPS tracking technology, portable types of GPS receiving devices are available in the market these days. Outdoor enthusiasts use GPS when they are out in the wilderness. They are valuable tools when going camping, hiking, trailing and fishing. They are even useful when navigating through streets and road. Some GPS receiving units even provide suggestion on which routes are less congested.
