Use Vehicle GPS locator to Save Your Money
A short history of GPS
Military, government, and civilian users all over the world rely on GPS for navigation and location positioning, but radio signals have been used for navigation purposes since the 1920s. LORAN (Long Range Aid to Navigation), a position-finding system that measured the time difference of arriving radio signals, was developed during World War II. The first step to GPS came way back in 1957 when the Russians launched Sputnik, the first satellite to orbit the Earth. Sputnik used a radio transmitter to broadcast telemetry information. Scientists at the Johns Hopkins Applied Physics Lab discovered that the Doppler shift phenomenon applied to the spacecraft — and almost unwittingly struck gold.
A down-to-earth, painless example of the Doppler shift principle is when you stand on a sidewalk and a police car speeds by in hot pursuit of a stolen motorcycle. The pitch of the police siren increases as the car approaches you and then drops sharply as it moves away. American scientists figured out that if they knew the satellite’s precise orbital position, they could accurately locate their exact position on Earth by listening to the pinging sounds and measuring the satellite’s radio signal Doppler shift. Satellites offered some possibilities for a navigation and positioning system, and the U.S. Department of Defense (DoD) explored the concept.
By the 1960s, several rudimentary satellite positioning systems existed. The U.S. Army, Navy, and Air Force were all working on independent versions of radio navigation systems that could provide accurate positioning and all weather, 24-hour coverage. In 1973, the Air Force was selected as the lead organization to consolidate all the military satellite navigation efforts into a single program. This evolved into the NAVSTAR (Navigation Satellite Timing and Ranging) Global Positioning System, which is the official name for the United States’ GPS program. The U.S. military wasn’t just interested in GPS for navigation. A satellite location system can be used for weapons-system targeting. Smart weapons such as the Tomahawk cruise missile use GPS in their precision guidance systems.
GPS, combined with contour-matching radar and digital image-matching optics, makes a Tomahawk an extremely accurate weapon. The possibility of an enemy using GPS against the United States is one reason why civilian electronic tracking device are less accurate than their restricted use military counterparts. The first NAVSTAR satellite was launched in 1974 to test the concept. By the mid-1980s, more satellites were put in orbit to make the system functional. In 1994, the planned full constellation of 24 satellites was in place. Soon, the military declared the system completely operational. The program has been wildly successful and is still funded through the U.S. DoD.
Vehicle GPS locator technology
Over the past several years, GPS receivers have become extremely popular and affordable. Lots of people who venture away from urban areas are carrying them. Cars come installed with GPS navigation systems for negotiating city streets and highways. Car tracking GPS are connected with the web based applications that come with the maps of streets which facilitate the users or the drivers to identify the quickest, direct and fuel-efficient route to destination. Some fleet tracking systems provide time reports in traffic conditions and even provide other diversion routes that aren’t traffic laden.
Start using Vehicle GPS locator and saves thousands and even ten thousands of money and improve the efficiency of your fleet. A bit of initial investment is required and with regular monthly maintenance, you can take exploit the advantages of this system to your benefit and reduce the operating cost of your company. The navigation functionality allows every fleet manager to locate the vehicles and precisely know the location of the vehicles at any time. With vehicle GPS tracker you can compile data on driver’s behavior and identify the drivers who drive fast, who brake hard and who accelerate the cars fast from a stop and many more such things. You can have a regular report of each and every trip taken up a by a driver. There are facilities attached with this system which allows the fleet manager to identify a particular vehicle exceeding the speed limit. By having continuous track on your assets you can improve the driving habits and safety and provide a better user experience to the customers as well.
