History of GPS

Global Positioning Systems (GPS) are modern navigation devices that employ satellite technology. You will find that these navigation devices are usually installed in vehicles. Because of its increasing popularity, the latest car models come equip with these mapping systems as a basic feature. Before these GPS devices became a must for every traveler, you should know that they were one of the most revolutionary equipments that the US government has ever designed.

Looking back, the concept of GPS was first introduced during the launch of Russia’s Sputnik in 1957. As the national government observed the spacecraft’s movement towards space, it was realized that there were radio signals being emitted by the said craft. This fact actually became the basis for research in the field of GPS. By the mid 1960s, the US Navy launched a satellite system, called Transit System. These satellites circled the planet and guided Navy submarines. After, the US Department of Defense decided to create the very first GPS device and by 1978, it was launched.

The Transit System today consists of 24 satellites, which circle the planet continuously. The information relayed by these satellites is used various purposes including navigation, tracking and GPS mapping. With the preciseness of these satellites, it is now possible to pinpoint a particular place o even a person. As GPS technology improved, the devices also became smaller and smaller. Now, you can have a GPS device that could easily fit on the palm of your hands. Amazingly enough, such small device holds a wealth of information.

For those unfamiliar with these GPS devices, you will find that they are quite useful especially if you are traveling in an unfamiliar region. With just a few clicks, you will be able to determine what routes to take in order to reach your desired destination. Most of these GPS system come with pre-loaded maps that you can search. These maps contain information about the local restaurants, hotels and gas stations. You can actually store information for routes in the United States, Canada and Europe. Such important information will surely be useful when traveling to these countries.

Some of these GPS devices also provide information about traffic conditions in real time. You will be able to avoid traffic congestions easily and not be inconvenienced by surprise detours. Most GPS devices of today are also designed to pinpoint the exact location of your car. They will certainly come in handy when you are in an over-crowded parking lot and you have no idea where you parked your vehicle.

The latest in GPS devices even allows you to store addresses and access audio books and information. You can also use them to locate a restaurant or hotel and book a reservation. By using these GPS devices, life has certainly become a lot more convenient. And with the industry continuing to make new discoveries and improvements, it is not surprising that these GPS devices will be one of the must haves in the future.
