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.
The invention of the GPS started with Dr. Ivan Getting leaving his position at Raytheon Company, and armed with the knowledge of what was at the time the most advanced navigational technology in the world, they began developing the Global Positioning System. He, Roger L. Easton, and Bradford Parkison began in the 60’s with a constellation of 24 satellites (placed in six orbital planes) orbiting the earth at a very high altitude (about
Henry Hudson (English seamen) started sailing with his ship named “the half moon” in 1609 for the VOC. Officially he was searching for a new trading route to Asia. He was searching for the Northwest Passage through North America on the west of the Half Moon. A lot of explorers did the same thing before him. But he didn’t found the Northwest Passage. But he did find something else, the New Netherlands. It had beautiful woods, animals and ...

Although this service sounds quite convenient and has its obvious benefits, there are other issues to be considered. For example, many ethical dilemmas that play from privacy issues. In a world when at one time you could take a walk to remove yourself from the eye of another, we not may be under constant supervision of sorts. Tracking devises are easily placed in many things, cell phones, which are used by nearly all people in today's American society, are the recent and most wide spread target for GPS. Is it ethical to track someone through an everyday devices such as a cell phone, is tracking people ethical in itself? These are the questions that must be resolved before we can celebrate the positives of such technological advancements.
To navigate during the night and day they looked out for well-known landmarks such as mountains. They could also follow the sun and stars or watch out for birds that were found at different times and places of the year. Navigators were needed in the time of Vikings as they were the key to successful voyages. Without them Vikings would have never been able to sail across Western Europe and leave an impact that would actually make way into our history. Therefore their would of not been any impact to live on today. One example was when the Viking found their way into the Mediterranean Sea and raided the coasts of Spain but of course with the help of navigation. In addition to navigation, religion also did impact.
The Five Themes of Geography are: Location – Absolute points on a map or grid or Relative to where something may be; Place – The physical and/or human characteristics of a locations; Human/Environment Interactions – How humans have impacted the landscape or environment; Relationship between places Movement – How humans interact on the earth (i.e. how they communicate over distance (short or long)) and Regions – a unit of space that has commonalities defined by physical, human and environmental geography. The Explorers of the New World may have not known what the Five Themes of Geography were but they quickly learned. Of the five themes the ones that they all took advantage of was the physical Location and Place as they learned to navigate to and from as well as through their new environments. Over Time the explorers began to discover the relationships within their environments and original occupants of the lands as well as the regions in which they now occupied.
GPS systems in earlier history, were primarily used by the military branches of our government to compete with other nations we had been fighting against. At the time, many people were trying to make that technology accessible to the public living in the United States. The idea of adding a GPS inside of a cell phone came to reality briefly before the year 2000. From then on, the GPS technology in cellphones has sophisticated in such a way never imaginable. A lot of good has come from this technology, but there has also been a lot of bad that has come from it as well.
...ting trek by land was one to be made by wagon, horseback, or on foot either way the most popular way started in Independence, Missouri and ended in California 2,000 miles and six months later. "Start at 4, travel till the sun gets high, camp till the heat is over. Then start again and travel till dark (Uschan 21)."
“Some of the world’s greatest inventions came from China.” Much of the world today has still been undiscovered. But without the compass the Chinese and Americans might not have known each other existed. With the compass, explorers were able to navigate their way through many of the seas and land into the Western Hemisphere.
The Age of Exploration began as a result of new technologies that guided explorers during sea voyages. Explorers used many tools and technologies during The Age of Exploration, to explore and make discoveries. Technology and tools that explorers used, included, caravels, compasses, astrolabes, and even sponsors. A sponsor is a person who gives money for an undertaking, such as a voyage. A sponsor would also provide money for materials needed for the voyage, such as, caravels, and other necessities. A caravel is probably the most important material needed for a voyage. A caravel is a ship designed for long voyages. Caravels have both square sails, and triangular lateen sails. However, they each provided/allowed different things. Square sails provided power, when lateen sails allowed quick turns. The compass, a Chinese invention, allowed sailors to track their direction. On the other hand, an astrolabe, an ancient Greek invention, improvised by the Arabs, would measure the angle of the stars above the horizon. This would help sailors find their s...
...regarded GPS – an indispensable part of GIS. Discussions on cartographic principles, commercial GIS software programs, satellite images, aerial photos, and geodatabases are some of the other conspicuous omissions in this book. There is an inconsistency in the depth of topics explored; for example map projections are explored in great depth, while vector topology is merely glossed over. These omissions and inconsistencies would in my opinion make this book marginally less beneficial to all the three audiences together. However, there is something for all them; structure for engineers, equations for engineers and students, and GIS concepts for students, engineers and users. This book will therefore be undeniably valuable if used to complement the material in some of the other fundamental GIS books in the discipline. It has merits, but there is room for improvement.
The following is a brief illustration of the principles of GPS. For more information see previous chapter. The Global positioning System (GPS) is a satellite-base navigation system that provides a user with proper equipment access to positioning information. The most commonly used approaches for GPS positioning are the Iterative Least Square (ILS) and the Kalman Filter (EKF) methods. Both of them are based on psuedorange equation:
There was a time a person would use a roadmap to get from one location to another. Some also would stop and ask for directions. Today, you seldom see paper maps and people stopping at a local gas station for directions. Many vehicles come with a navigation system that provides a real-time map of the vehicle’s current location as well as systematic directions to requested destination.
...uch easier to locate. GPS has had a far reaching effect on how we move from place to place whether the passenger knows it or not. There are too many effects that gps has had for me to keep this short, but gps has made its mark however, gps is not a replacement for good old fashioned navigational skills it is just a convenience.
... of seafaring navigation, and this process had made the world a much smaller place. Furthermore, European geographic knowledge was expanded immensely by Magellan’s expedition, and his ambitious voyage around the world provided the Europeans with far more than just spices. Also, he discovered the Strait of Magellan, and named the Pacific Ocean (“Ferdinand Magellan”). Moreover, mapmakers gained more knowledge about the shape and size of South America and the Pacific Ocean, and knew more about the location of Asia in relation to Europe and the Americas. This mapping proved invaluable source to European understanding of the world. The most important geography is Magellan’s realization/understanding of full extent of the earth, which was something that significantly helped in the development of future geographic explorations and the resulting knowledge of the world today.
