The credit of developing an extensive system like GLOBAL POSITIONING SYSTEM (GPS) goes to The US Department of Defense. It is one of its kind system using the transmission signals and network of twenty-four satellites orbiting 12000 miles above the earth. It then points to the receivers’ location. It also indicated the direction as well as the speed of travel.
Initially, this technology was restricted only to military operations. It was authorized for civilian use in 1983 after a Korean airliner was shot down by Russian airspace. The feasibility of this technology was such that it became widely used navigation aid throughout the world.
Development since 1983
The commercial and civilian use of navigation system led to more accurate and compact devices. Many drivers across the USA rely on built-in navigation systems even in extreme terrains to keep themselves on correct routes.
How GPS works in Vehicle?
The GPS navigation system can be pre-installed with a device in new cars, trucks, bikes as well as other big vehicles. It uses a combination of satellite signals and interactive onboard maps. These systems generally include all the information about road diversions, speed limits, turn restrictions, local businesses as well as any small routes or by-lanes.
The built-in system then plots several routes between two places based on n number of variables like – the size of Vehicle, driving capacity, and nearest fuel stations. It also accounts for on-going construction and congestions while determining the best route of travel. The navigation systems today are equipped with suggesting corrected ways if Drivers miss a turn or some exit. It also helps drivers find the nearest gas stations as well as their choice of restaurants on the route.
The navigation systems are equipped with such an UI that allows adding multiple stops while completing the journey. It helps the driver to plan the route well in advance and calculate the journey time.
As found by our global experience, over 18-22% of routes change every year. Many new businesses, constructions, and diversions are added to several roads.
The local maps and navigation change dynamically as compared to major routes and highways. Thus, every driver needs to keep their systems well updated with the latest on the go information.
Due to the volume and speed of changes in roads, exits, and new attractions around the city, it has become essential to keep the navigation systems well served.
Map updates can be done by automobile manufacturers as well as online service providers. The most important aspect of these navigation updates is that it should be done as per the requirement of the driver. For example, if the majority of the commute is done locally, then a global map update is an unnecessary expense for the driver.
