Global-navigation Satellite Systems (GNSS) provide navigational data to airborne transportations and various other applications. Mainly two satellite constellations are in use today for navigational purposes. They are global positioning system (GPS) which is provided by the United States and global navigation satellite systems (GLONASS) which is provided by the Russian federation [1]. GPS and GLONASS satellites fly in medium Earth orbit (MEO) at an altitude of approximately 20,200 km and 19,100 km
Introduction: 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
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
since the first artificial satellite was propelled into space, the use of GPS satellites has rapidly increased. There is evidently conflicting evidence over whether the ethical, moral and practical implications of putting GPS satellites into orbit are positive or negative. This paper investigated the idea that GPS devices can help solve crimes and enhance security, but there are nevertheless potential perils posed by the abuse of GPS technology and orbital debris from satellite collisions. Taking everything

Overview Global Positioning System or most commonly know as a GPS is a technology originally developed at the height of the cold war in the 1960s and it was designed for military intelligence applications and missile target accuracy. This technology is managed by the United States and it uses more than 24 GPS satellites that transmit signals allowing GPS devices or receivers a precise location, directions and sometimes speed of travel of an individual or vehicle. With the exponential growth
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
Electronic navigation systems are presently a very significant component of marine, land and aeronautic navigation as a result of their important role in ensuring safe navigation. Navigation is according to Oxford Dictionaries (n.d.) “The process or activity of accurately ascertaining one’s position and planning and following a route”. They help navigators to locate their positions in land, sea and air. In marine navigation, there are many types of navigation systems were used by mariners. Some of
GPS (GLOBAL POSITIONING SYSTEM) The Global Positioning System (GPS) is a space-based navigation system which provides information on location and time under all weather conditions, anywhere on or near the earth where there is an unobstructed line of sight to four or more GPS satellites. The system provides critical capabilities to military, civil, and commercial users around the world. The United States government created the system, maintains it, and makes it freely accessible to anyone with a GPS
use this data, we must be able to retrieve records accurately and reliably for a desired patient population, usually through the use of natural language processing (NLP). While NLP has been applied to EHR data for decades, the performance of these systems has been variable across the techniques used, as well as the clinical task. The Health Record of people is stored electronically in the Cloud. The EHR is accessed by RFID tag provided to the individuals. The RFID tag is identified by the RFID reader
how. Getting lost, taking the wrong roads, hours of riding with no knowledge of our whereabouts. But, the GPS is a helpful invention that navigates us throughout the world. Do you know how GPS Systems work? GPS stands for Global Positioning System. It was the first system available since the 1980’s. The system was invented by the U.S. department of defense. It was intended for military use only. http://www.pcmag.com Military added interference to the signals to ensure their own version was the only
To understand where the Global Positioning System first began we have to go back to the time of the Cold War. It was in 1957 when the Soviet Union launched the first ever man made satellite into orbit. This satellite was launched as a demonstration of technological advancement and strength over the U.S. What the Soviets least expected was that two Americans would soon find this satellite essential in the discovery of an amazing new technology. Two physicists by the name of William Guier and George
At one time these technological developments even could not imagine by people, now it is truth that we live in. Sending astronauts and satellites into space resulted in new capabilities and products that have transformed our culture and created a major sector of the global economy that worth trillions of dollars. So in that perspective continuing to explore space is more reasonable. As it was in the past to expect that investing billions for exploring
How would pilots ever get around so easily without the help of navigation aides? Navigational aides have been around for almost as long as aircraft have been flying in the skies above us. The first navigation system was composted of just a high intensity-flashing beacon. These beacons were placed on the flight routes that were popularly flown in the mid 1920’s. With more time more of these technologies that help us navigate the world will be even simpler than today. This paper will explain how some
Navigation Early Explorers such as Christopher Columbus and Magellan relied on landmarks for early navigation, which could result in serious miscalculations. Later explorers discovered they could use the stars as their primary choice for navigation. As technology increased the compass and sextant were used in navigation purposes. The needle of a compass always pointed north, while the sextant used adjustable mirrors to measure angles of the moon and stars. The sextant could only calculate
considerations of using non- traditional timekeeping systems, such as GPS Time or a time scale maintained by an individual government contractor. Instead, why don’t we just switch to using atomic time that is accurate, continuous and doesn’t vary for millions of years? The continuous use of a non-uniform time scale by including leap seconds, will definitely cause problems in many walks of life especially now that technology relies heavily on satellite communications that require precise timekeeping.
Least Square for GPS navigation This chapter describes an experimental of using Iterative Least Square (ILS) with the application of GPS navigation base on Matlab programming software. The psuedorange and satellite position of a GPS receiver at fix location for a period of 812 seconds is provided. 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
place to ask for directions. This entire struggle to get to our destination has changed during the past years. Now it’s much easier to find places with the new navigation system, it was created to help people drive and get faster to their destination. The global positioning system (GPS) is
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
Although Global Positioning technology has existed since the mid 1970’s, some of the most significant advancements have taken place within the last five years. In recent months, studies have been conducted by NASA and other institutions concerning the use of advanced GPS technology in both computer controlled flight of commercial aircraft and the establishment of “no-fly safety bubbles” around designated areas and buildings. In essence an aircraft’s computer system would override a manual command
