GPS and RFID Package Tracking

Wednesday, November 5th, 2008

By Michael Russell

It was not that many years ago that package tracking was almost totally guesswork. If you ordered something that needed to be shipped to you it might arrive in 3 days or 3 weeks and where the package was in between the shipper and you was a complete mystery. All of that is changing not only because of GPS tracking but also because of radio frequency identification (RFID).

Understanding The Basics Of GPS by Beau Hooks

 The GPS (Global Positioning System) has been fully functional for nearly two decades. GPS consists of 27 satellites positioned in a medium earth orbit. A satellite is considered to be in medium earth orbit when it is 35,000 kilometers above the Earth’s surface, roughly 22,000 miles. The first experimental satellite was launched in 1972. It was not until 1995, 23 years after the launch of the first experimental satellite, that GPS bore fruit as a fully function satellite tracking system.  Even then the system was restricted to military and airline industry use.

Global Positioning Is Free – How GPS Works And Why You Should Use It

Thursday, November 22nd, 2007

As most of you know GPS is an acronym for Global Positioning System, but how does global positioning really work?

The Global Positioning System is a satellite-based navigation system, consisting of more than 20 satellites and several supporting ground facilities, which provides accurate, three-dimensional position, velocity, and time, 24 hours a day, everywhere in the world, and in all weather conditions.

The Global Positioning system consists of three main components:

1. GPS Ground control stations.

The Future of GPS

Thursday, December 28th, 2006

The use of Global Position System (GPS) has become quite diverse from automobiles, mobile phones, tourist facilities, city maps, and even pet collars. GPS works through a network (often called constellation) of 27 satellites that move around the Earth in geo synchronous orbit. These satellites exchange relative data to fix the position of one particular object on the surface. Similar to the Internet, the technology was original implemented for military use in order to help precise control of troops as well as getting accurate information about enemy troops and armament placement and movement. And like the Internet it was soon the commercial use that would dominate global reliance on GPS.
