The Global Positioning System

According to the U.S. Department of Defense, they “made up a network of 24 satellites placed into orbit” (Garmin 1). Due to the satellites in orbit, the GPS knows the whole earth and is able to find your exact position by signals being passed through earth. GPS devices go through a process of trilateration to be able to find the exact placement of the citizen. A GPS only needs various satellites to be able to show a map and the position of the user. There are three components needed for a GPS to work properly: the Space component, the Control component, and the User component. The Space component contain the 24 satellites in orbit that transport signals from space to the GPS device. The Control component is monitored by the U.S. Air Force to make sure all of the satellites are doing their job properly. According to a government website about GPS devices, The U.S. Air Force “develops, maintains, and operates the space and control segments” (“Global Positioning System”). The User component is the actual device owned by the public to hold or to place in a car. The system is very accessible to all, and is able to work in any weather conditions while having no fee subscriptions to run the device. Throughout the years, the Global Positioning System developed many new features so they can make it more advance for people, while making it convenient to use anywhere. Features of the

One technology used by geographers is remote sensing. Remote sensing is the acquisition of data using different satellites located around the Earth. The satellites will scan the Earth and relay that information back to an information center/base back on Earth. Some of the uses of remote sensing are that geographers are able to use the information they get from the satellites to map different features across the world such as agriculture, drought, and sprawl. Another type of technology used by geographers is GPS (global positioning system). GPS is enabled by a multitude of satellites, tracking stations and receivers to relay the information. GPS most common use is transportation. GPS will locate a vehicle's current location and the give directions

Sometimes the GPS signals are not accurate due to some obstacles to the signals such as buildings, trees and sometimes by extreme atmospheric conditions such as geomagnetic storms.

A GPS is used, to get a rough location of the car, at which point radar, lasers and cameras take over to monitor the world around the car, 360-degrees. The software can recognise objects, people, cars, road marking, signs and traffic lights, obeying the rules of the road and allowing for multiple unpredictable hazards, including cyclists. It can even detect road works and safely navigate around

The Global Positioning System (GPS) is a constellation of twenty four satellites that can pinpoint any position on earth using a GPS receiver. Used to calculate exact position, speed and time, there are tremendous

1. By using GPS device, it is possible to track the location of soldiers when it is needed.

In this high-tech environment of the 21st Century, most everyone who drives a car or carries a cellphone has heard of the Global Positioning System (GPS), but few could provide details on the origin, development and many uses of this system, outside of basic everyday navigation. This paper will explore the origin and development of the Global Positioning System, as well as analyze various uses of this system. Some of the practices include Military use, surveillance of those convicted of violent crimes, tracking of wildlife, and location based services as it applies to the Cellular Communications Industry. This paper will also explore the reality of the Global Positioning System as it relates to a Christian worldview.

Instead of using radar data to keep aircraft at safe distances from one another, in the future, signals from the Global Navigation Satellite System will provide air traffic controllers and pilots with much more accurate information that will help keep aircraft safely separated in the sky and on runways.

GPS tracking and positioning is also incorporated into every automated car, for the self-evident purpose of informing driver and car where they are and where they're going. Some cars

TerraCog Inc., is a company that offers global positioning systems particularly to consumers that like to be outdoors. TerraCog had proven that even though they aren’t always the first to the market they still have a great product. This great product was better than their competitors and they also were able to address customer’s needs. They are known for a product that is durable and has multiple features such as an integrated compass and a barometric altimeter. Precise navigation is the area that TerraCog stands out in. Their proprietary firmware allows this to happen. TerraCog has been working on a new product aimed toward the cycling and fitness market they have yet to tap into. If it weren’t for Posthaste and their new unveiled GPS

Garmin is the leading worldwide provider for navigation1. It has been setting the standards for the Personal Navigation Devices (PND) with the creation of superior products and providing the users with what they need from their PNDs. Other than your personal GPS for your car, Garmin has also been in the market for other incredible devices. Their products are readily available for marine, aviation, fishing industry. It provides GPS navigation systems for the marine and aviation industry. It provides aquatic life updates for the fishing industry along with the GPS technology. They have also been recently working on their premium line of wearable devices to promote health and fitness. They provide GPS sensors for the market where these can

Second, smart cars can monitor real-time traffic conditions by using satellite navigation to map out the best route, in order to reduce the traffic jams.

GPS works off of twenty-four satellites located 11,000 nautical miles above Earth's surface. These satellites track receivers, which are on Earth. Receivers can be GPS in a car, a chip located in a cell phone, military tracking devises, police radios, or even something as every day as a watch. The distance between the satellite and receiver is measured using the exact distance from six different satellites that locates a particular receiver on a particular path at the intersection of the two satellites. The exact distance and time that it takes to measure the distance is tracked and formulated to produce the exact longitudinal and latitudianl axis of the person being located. As complicated as the mathematical procedures sounds, the radio signals are transmitted instantaneously and the close approximate location of a subject is known at once.9

GPS is an important measure used in field surveys to accurately determine the position of a site. In this case, it was used to map the Capel Dewi MST mast array. At each mast on the border of the array, a measurement was taken in order to obtain a grid reference. The reference point was set up and coordinated accurately, and post processed accordingly. The data was then collected around the array and was repeated with three different rovers to measure precision and view the effects of using a different satellite system; the first two were ******** receivers and the third was a GLONASS receiver. The third rover was unable to obtain data on one side of the field as bushes were blocking the satellite signal. Data was spliced into the original data set to make up the shortfall. The precision of the data varies across the field, generally with a higher precision closer to the reference point. This is caused by points further away from the reference points going through the same post processing as the reference point, and as its true position is further from the reference point, the post processing is less accurate. However, there is some degree of variation from point to point depending on the position of the rover as the measurement was taken.

GPS (Global Positioning System) is the vital share holder in this business. The vehicles for hire come with a GPS installed in them, which keeps the company always informed about the customer’s geographical location.
