GPS: Greatest Invention Since 1898

The GPS, like many other technologies, has greatly impacted every aspect of modern life. At first the GPS was created primarily to be used for military purposes but due to events that occurred during the Earth's history the GPS was later released to the public. However, before the GPS was created people had to use other means of navigating to get from one place to another. As time went by these alternative methods of navigating became more advanced and practical. These methods slowly led to the creation of the GPS. The GPS has gone through many technological advancements that are now currently in everything ranging from cell phones and watches to ATM's and bulldozers.
In fact before the Global Positioning System was invented, early travelers had to use other means of navigating in order to arrive at their destination. These early navigating methods included landmarks, dead reckoning, and celestial navigation. Landmarks were the earliest means of navigating. It was the first type of navigation that was used to get to different places. But using landmarks as a type of navigation was difficult due to the environment constantly changing from human interferences and from natural processes (National Parks Service).
Dead reckoning was another type of navigation that was applied for traveling across oceans. This type of navigation used a process that calculated one's position by using a previous location that is based on known speeds that occurred over time. When using dead reckoning one would figure out that the process is complicated and the measurement tools used in the process gave out inaccurate results (National Parks Service).

...vice providers and airspace users, increased safety, increased safety-of-life capabilities such as EGPWS. Another application will include the environment. In this application the benefits of using a GPS will be able to trend any patterns in the environment to create maps, quickly analyzed without using field data that is in digitized form, accurate tracking for environmental disasters including oil spills, monitor endangered species, and provide data on seismic monitoring. This is only a few applications that the GPS can help with, but the GPS still provides many benefits to other applications (GPS).
To sum it up, the GPS has been able to find its way into every known electronic know to mankind. Plus navigation as a whole has gone through many advances that have caused it to be part of many projects. Also the GPS has greatly impacted every aspect of modern life.

In this essay, the author

  • Explains that the gps, like many other technologies, has greatly impacted every aspect of modern life.
  • Explains that before the global positioning system was invented, early travelers had to use other means of navigating in order to arrive at their destination.
  • Explains that dead reckoning was another type of navigation that was applied for traveling across oceans.
  • Explains that celestial navigation was a time-consuming and complicated task of measuring the angles between the stars. the sextant and the timepiece were later invented to help travelers figure out their position.
  • Explains that ground-based radio navigation systems were built in the 20th century, with transmitting towers that allowed receivers to calculate distances.
  • Describes omega as the first global navigational system, which provided high frequency signals that allowed for high accuracy in finding a user's position.
  • Explains that in 1983, a civilian flight of the korean airline was shot down after entering soviet territory. president reagan announced that gps capabilities would be made available to the civil community beginning in 1984.
  • Explains that the gps is a us owned system that provides users with positioning, navigation, and timing. the us air force develops, maintains and operates the space and control segments.
  • Explains that the gps space segment consists of a constellation of satellites that transmit radio signals to users.
  • Explains that the air force has a global network of ground stations that track each of the gps satellites.
  • Explains that the user segment consists of everyday applications that occur in every aspect of modern life, including agriculture, aviation, environment, marine, public safety and disaster relief, rail, recreation, roads and highways, space, surveying and mapping, and timing.
  • Explains that gps has impacted our lives in more ways than one could imagine. it can boost productivity in agriculture, construction, mining, and many other areas.
  • Explains the benefits of using a gps in agriculture, aviation, and the environment.
  • Explains that the gps has been able to find its way into every known electronic know to mankind, plus navigation as a whole has gone through many advances that have caused it to be part of many projects.
