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.
The Global Positioning System consists of three sections, 1.satellites which are orbiting the planet, 2.there are numerous control/monitoring centers here on the ground, and 3. gps receivers which are used by their owners. The satellites send down signals from orbit, which are received by GPS receivers on the ground in the air or on the water, the GPS receiver then converts this information into a location longitude, latitude and altitude along with time.
Consumers may purchase such technology for varying different prices, which greatly depend on the application in which the unit is to be used as well as the many different types of functions that are available to the market. For instance one may purchase a marine gps unit for their boat that has a mapping capability along with sonar (depth/fish finder), the cost of such a unit can vary greatly by manufacturer as well as region and whether or not it is a color unit or a monochrome unit, color being the more expensive. Other factors that play into cost of units are their application alone; aviation ...

...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.

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.
Jane Rogers the financial manager at Plants Inc. a landscaping business in Chicago concurs that employers should ethically implement the use of GPS tracking in their companies. Rogers uses GPS to track and monitor outfield workers during working hours and argues that it increases efficiency and promotes confidence in prompt services to clients. Rogers supports the need for restrictive and regulative legislation in GPS tracking to create parameters within which employers can operate and be held accountable. She points out that she passively tracks employees during working hours and only resorts to active monitoring of employees after she has received complaints from clients. Rogers also states that she reminds her employees to turn-off their
Latitude- is an artificial system of individuation of sites on the Earth's surface. Latitude are the horizontal lines running across the globe, that is from east to west are called lines of latitude. They are parallel to the equator, and are numbered in degrees North or South of the equator. Latitude determines the position of a place.

Geographers plan new communities, decide where new highways should be placed, and establish evacuation plans. Computerized mapping and data analysis is known as Geographic Information Systems (GIS), a new frontier in geography. Spatial data is gathered on a variety of subjects and input onto a computer. GIS users can create an infinite number of maps by requesting portions of the data to plot.
GIS is an emerging method of data storage and interpretation. GIS is, simply put a database. It is many tables of data organized by one common denominator, location. The data in a GIS system is organized spatially, or by its physical location on the base map. The information that is stored in the database is the location and attributes that exist in that base map, such as streets, highways, water lines, sewers, manholes, properties, and buildings, etc. each of these items don’t just exist in the database, the attributes associated with the item is also stored. A good example of this would be a specific sewer line, from and arbitrary point A to a point B. Ideally, the sewer line would be represented graphically, with a line connecting the two points or something of the like. When one retrieves the information for that line in particular, the attribute data would be shown. This data would include the size of pipe, the pipe material, the upper invert elevation, the downstream invert elevation, the date installed, and any problem history associated with that line. This is the very gist of what a GIS system is.

The GPS is sensing knowledge to help with navigation with the car and destinations. Autonomous cars are not yet available on a large scale of the world such as out of the United States of America, but have been programmed and developed to travel along the roads of America. Most autonomous cars are programmed only for American roads, we have made a big step towards the future with autonomous cars, with them being only available mainly in America, they are a luxury. They are making their way to larger scale autopilot features, and will eventually be available on a larger scale.(Ali

Satellite is basically working by the principle of calculus and analytical geometry it take the signals from sourse from one part of the world and send it to the defferent part of the world with in second etc.
The antenna emits radio signals to activate the tag and to read and write data to it. Antennas are the conduits between the tag and the transceiver, which controls the system's data acquisition and communication. Antennas are available in a variety of shapes and sizes; they can be built into a door frame to receive tag data from persons or things passing through the door, or mounted on an interstate toll booth to monitor traffic passing by on a freeway. The electromagnetic field produced by an antenna can be constantly present when multiple tags are expected continually. If constant interrogation is not required, the field can be activated by a sensor device.

We have cars with WIFI and Bluetooth capabilities to accommodate our use of the cellular phone, let us not forget the nifty GPS apps that make navigating so much easier with that IPhone, Galaxy, or whatever model mobile phone one carries.
