GPS Protects the People and Items You Love

By: Barry Jenkins

Global Positioning Systems (GPS) have been changing the way the world works since its inception as a tool for soldiers during World War Two. Although the design may have been different, the idea of GPS has been around for over half a century.

The design of the GPS is based on similar radio navigation systems, called the Decca Navigator, and were first used in the 1940's. When the Soviet Union launched the world's first satellite "Sputnik" in 1957, U.S. scientists discovered that radio transmissions sent from the satellite could be used to pinpoint where the satellite was in relation to the earth. Thus, the idea of the birth of the modern-day version of the GPS was created.



The very first satellite navigation system, which was used by the United States Navy, was tested in 1960. As the technology developed, so too did advancements in locating your position in the world. In the 1970's, the Omega Navigation System became the first world-wide radio navigation system. It was not until 1978 that an experimental Block-I GPS satellite was launched into space, ushering in a new era for civilian use of GPS. The amount of satellites using GPS' have increased over the past 30 years, and as a result, many people have benefited from the use of navigation tools used by the GPS.



The civilian benefits of using a GPS are almost unlimited. The ability to determine the receiver's location allows GPS receivers to perform as a tool for surveying and also as a tool for navigation. The GPS has the ability to determine relative movement, and as a result, can calculate local velocity and orientation. These benefits are most commonly used in vessels or photographs of the earth. Time transfer is also a GPS skill which allows clocks to become synchronized to exact standards. GPS has revolutionized the synchronization of the planet - there aren't very many tools out there that can say the same thing!

Finally, by using the GPS measurements of the planet, scientists are able to better understand the Earth's environment, such as the atmosphere and planet's gravity. By observing how those environmental components alter the prorogation of GPS signals, scientists can find out new information on the progression of the planet.

Since those early days in 1993, the GPS system has come a long way. In 1994, a complete constellation of 24 satellites was in orbit around the Earth.

By 1996, U.S. President Bill Clinton, issued a statement that declared the creation of an Interagency GPS executive board - as a result, GPS systems became more advanced and enhanced user accuracy and reliability, particularly with aviation. The most recent launch of a GPS satellite was in November of 2006, with the oldest satellite still in orbit since 1991, still circling the globe.

GPS systems have come a long way since the idea came to fruition in the Second World War. GPS has allowed the common person the ability to navigate, with exact precision, around the globe. When you know where you are in the world, you can go anywhere! These units are very important to personal safety as they can be used to track vehicles and other valuable items. Here are some ways that citizens are using GPS:



(1) In their cars so they know where their teenage drivers are and that they are safe.

(2) To help retrieve stolen vehicles faster.

(3) To track shipments and other traveling goods.

(4) To prevent kidnappings with GPS teddy bears and backpacks.

(5) GPS units are extremely helpful to both civilians and military personnel alike. However, to help prevent civilian GPS guidance from being used as improvised weaponry, the United States government controls the export of civilian GPS receivers. For this reason it is very important that you purchase your GPS system from a reputable merchant.



Whether you are interested in GPS, or simply are interested in gathering information for a future purchase, it is important to find reputable merchants. Your first step when looking for an effective self-defence should be at . This company offers a large variety of merchandise, including GPS systems, and provides education on the necessary information needed to protect yourself and your family.
