In the early 1920s, we didn’t have navigation systems or geostationary satellites. But motorists those days had a navigational watch: Plus Four Wristlet Route Indicator. A navigational device that fit on your wrist that you can use for navigating and driving directions. A driver could scroll using the knobs along the map to find out their route.
While a little smaller than an average map, when the driver maxed the map’s limits, It included tiny exchangeable instruction maps that you simply scroll manually to find out which streets to use when travelling. Coming with 20 maps, the Wristlet Route Indicator cost Five Pounds in 1927. When inflation considered, the price is about £50 today. The Plus Four Wristlet Route Indicator is on display at National Trust house. It is thought to be the first navigation device.
Today, we have smartphones with GPS navigation, GPS watches, and tracking devices to assist us in navigating through city traffic. But have you ever wondered how?
GPS was initially intended for military and intelligence use by the US and Russian governments. Credit for developing the GPS is assigned to a large number of scientists. Some controversy came to exist regarding who invented the idea of using geostationary satellites orbiting the Earth to determine the position of a receiver on Earth. The National Inventors Hall of Fame inducted Brad Parkinson for the invention of the GPS Systems. Ivan Getting from the Department of Defense is recognised as the inventor of the GPS. Roger Easton was recognised with the National Medal of Technology from the president of the US in 2004 for visionary work and pioneering actions with the development of NAVSTAR- GPS. Because of these scientists, GPS has entered the consumer industry and is incorporated into smartphones and vehicles these days.
Through the original purpose of providing the military with a highly effective instrument to trace their enemies or as a search and rescue tool, GPS has gone public exactly where it became popular for business or individual use. Tracking devices are now lightweight as much as 100gr and transportable. There are smartphones with a GPS tracking application that parents can use to track the location of their kids and they can even find and locate a good restaurant using GPS. Securing personal properties like car, bags, and other tools can be done remotely using a PC or smartphone. Businesses are investing into tracking devices which can be used for navigational purposes or route selecting for drivers. There are scientific uses such as map- making, earthquake exploration, environment scientific studies and tracking wildlife to understand the behaviour of animals.
Today, the Air Force manages a total of 31 operational GPS geostationary satellites. These satellites beam location information back to earth on a continuous schedule and GPS Tracking devices pick up this location information. The tracking devices compute its location using data received from several satellites around the world. Once this information is received, it’s transmitted using a cellular network to GPS Tracking servers, where it’s displayed to the end user on a map.
Many businesses and individuals use tracking and navigation devices to enhance security. When a GPS vehicle tracker is fitted into your vehicle, it will store and send out the positioning data of the car 24/7. Not only the positioning of the car, but it also gives data like fuel usage, engine condition, speeding records and telematics data. Getting and setting up a tracking system is the smartest thing to do if you own a vehicle and want to improve your security as well as navigation skills.
