Intro: The Global Positioning System (GPS) is a navigation system that provides information such as location, speed and time anywhere around the world. The GPS is a network of approximately 30 satellites constantly orbiting the earth. These satellites can precisely pinpoint the location of a GPS receiver anywhere around the world. The introduction of this new technology which can be used for many purposes has changed society and the environment both positively and negatively. GPS has made navigation extremely easier, as well as making travelling safer, it also has the ability to be able to locate and track criminals. GPS can also benefit the environment by tracking endangered species of animals, aiding with weather forecasting and the prediction …show more content…
GPS can be used to do anything from car navigation to missile or drone technology and just about anything in between. The ability to pinpoint locations has made navigating an unfamiliar area in your car or on foot much easier. Emergency services can also use GPS to find their way to an incident quicker than ever before. This can be extremely useful for search and rescue teams at sea as there are no land marks to go by. (MiTAC International Corporation, 2011)
GPS is also used aircraft to greatly increase the safety and efficiency of air transport. GPS aids air travel by enabling three-dimensional positioning and speed, as well as general navigation between airport and on approach to landing in bad visibility. (National Coordination Office for Space-Based Positioning, Navigation, and Timing, 2014)
Another large used of GPS is by the military for drones and missiles. GPS is used on missiles to guide the way to their target. It does this by pre-programming in the GPS coordinate of the potential target and the terrain surrounding it. When the missile is launched it reads its current GPS position and plots its route to the target. This makes it able to fly low over the terrain making it harder for radars to pick
3. X-Band/Ground-Based Radars: These radar systems gather tracking information regarding the incoming warheads during the mid-course phase of the missile. This data is then sent to the BM/C2, which in turn is sent to the GBI for guidance to intercept the warhead.
Often times its hard to imagine how the world survived without cell phones. Its an automatic response, when you see a car accident you take out your cell phone and dial for help, or when a child is waiting for a ride they will call their parents to see how far away they are. It is a great convenience for society to be able to do such things. Imagine if you didn't even have to call somebody to find out where they were. It may seem like a futuristic idea, humanity being capable of such mind reading; however, the advancement of GPS, global positioning systems, those ideas are coming to life in the present. GPS is a way to track one's position at anytime. This is done through the use of satellites monitored by stations on the ground. There are signals transmitted from a given satellite to the receiver on Earth. It is this information that gives precise location to one's whereabouts.
Does one ever think of the potential catastrophic harm they’re causing by turning on the lights or by using their cars? Don’t we want a world where our grandchildren and great grandchildren can live safety and comfortably? At the rate were going this will not be possible; we’ve added more than 1.4 trillion tones of Carbon Dioxide (CO2) in just two hundred years, and its messing up our planet (Siegel 1).
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
...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:
Many of us don’t get out of bed in the morning without checking our phone and going on the internet to see what the weather will be like for today, calling our friend to see where to meet before school, and instantly turning on our favorite songs to get ready to. Thanks to the 1990s, all of those things are possible. The 1990s introduced technology such as the internet, cell phones, cd’s, and many other things that has changed the world, and made communication and finding information faster and more convenient.
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.
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.
Cell phones have made traveling safer since the person is no longer having to find a house phone to use, which resulted in going up to random houses and asking to use their phone.... ... middle of paper ... ... Which is basically because of technology. Technology has also helped many people survive death.
How have portable devices changed society 's lives? Portable devices have changed society 's social lives, communication skills, and ability to send and receive information in a positive and negative way. Throughout the years there has been a drastic change in everyone 's life. Portable devices have been updated to make everyone 's lives easier, life is all about technology now.
Technology has continually transformed the way the human race lives and interacts with one another. From learning how to better cultivate the land that allowed for hunters and foragers to settle and grow their population, to being able to send out a tweet to millions of people all over the world, technology has transformed human interactions and expectations. It has allowed for people to collaborate and work with others across the world in real time and allowed businesses the ability to globalize. This paper will explore the impact of technology on the human race before the 1800’s, and how it affects our modern society, and the possible implications on future generations.
The Global Positioning System, more commonly called the GPS is a satellite based system that provides navigation for almost everything from cell phones to automobiles. This wonderful technology is very vital in today’s economy because of its prominence in banking, financial markets, power grids, farming, construction and so much more. It also protects human life by preventing accidents, helping in search and rescue missions and is critical to nearly every facet of military operations. There are three segments that make up the global positioning system: the space segment, the control segment and the user segment. The segment we are familiar with is the user segment. The user segment is what receives GPS signals, determines the distance between a satellite and a receiver and solves the navigation equations, all in order to obtain the coordinates of a specific place. The space segment consists of 31 satellites but there is an availability of at least 24 satellites that are approximately 6 000-12 000 miles above the earth.
GPS is a system of satellites radio-transmitters that orbit the planet in great numbers; their purpose is to be able to pinpoint the exact location of an individual or any type of vessel that is equipped with a receiver transmitter within a very small radius. GPS navigation has had a great impact upon society in general as well and its commercial and military applications. Global Positioning is made available at no cost to anyone who has a GPS receiver unit anywhere on the planet. A GPS unit is able to give the user longitude/latitude information as well as, altitude, traveling speed, distance traveled, distance remaining and time in any type of weather conditions imaginable.
We have benefitted our world by using satellite technology to preform tasks and provide a range of innovated services. The main applications of satellites are in the fields of communication, Earth Remote Sensing, weather, and scientific research. In some ways the use of satellites has made our world smaller. Satellites make it possible to establish a connection between two people that are on opposite ends of the globe via a telephone call or the use of the internet. Each of these satellites have many parts, but two parts are common to all satellites are called the payload and the bus. These groups of devices make the satellite capable of accomplishing their tasks.
