GPS (Global Positioning System) represents a technology that offers serious benefits to enterprises using mobile computers. Basically, it was developed by United States Department of Defence (DOD) for military and government use, but the information it provides is now available free for civilian and commercial uses worldwide. In layman language, GPS is a broadcasting system in which satellites transmit information toward Earth. GPS receivers take the transmitted information and use a form of triangulation to calculate the user's exact location. Basically, there are two types of GPS in use that are Autonomous, or Active, GPS (GPS receiver has the ability to resolve the device's location) and Network Assisted, or Aided, GPS (which relies on a GPS receiver associated with a Wireless Wide Area Network that is supported by network location server technology to resolve the unit's location. But, as in any technology deployment, real benefits only come from solutions that are well thought out in advance. There are many well-known uses for GPS, like real-time tracking and turn-by-turn navigation; the power of GPS solutions for enterprises often comes out of less obvious applications of the technology. GPS and mobile computing have created a technology that reaches and improves every aspect of enterprise field operations. From improved performance in the field to gaining better understanding and control over activities, GPS promises to change the way enterprises manage their operations in the field.
