What is GPS? The acronym stands for Global Positioning System. It is the new “Polaris” that aids in navigating, positioning and tracking with the use of a satellite-controlled system that broadcasts signals to the equipment on the ground. With receivers hand carried by users, GPS determines the exact location of a vehicle, person or assets and other things useful and valuable to which it is attached and records the position at regular intervals. It is a powerful tracking system that has provided the world with diverse applications for the military and civilian users.
What is GPS? The GPS is a space-based radionavigation system controlled and funded by the U. S. Department of Defense and operated by the U. S. Military. This is the GPS Operational Constellation. The tracking system has space segments consisting of GPS satellites sending signals coming from space. There can be at least 24 operational satellites orbiting in 12 hours that recapitulate the same ground track as the earth turns underneath them. The GPS satellites then transmit the data in a very precise time reference plied by what is called “atomic clocks” onboard the satellite. These atomic clocks then passively transmit the navigation messages in specially coded signals, enabling the equipment on the ground called “receivers” to compute position, time, direction and velocity in three-dimensional locations known as latitude, longitude and altitude.
What is GPS? Your Most Reliable and Most Precise Assistant
The GPS was primarily for the use of the military. However, after the Korean Flight 007 in 1983 tragedy, which would have been prevented had its crew only had access to better navigational tools, President Ronald Reagan issued a directive which would guarantee that GPS signals be made available to the world for free or without restrictions. Though it was intended for civilians as well as military applications at first, from its design, civilian users would not be getting the same accuracy that the military could.
Going public, what is GPS serving the commercial market? GPS became the new powerful tool that improved efficient routing of vessels at sea. It has saved a ship’s navigator hours of celestial inference and calculation. GPS enhanced safety at sea made it possible to report precise position to rescuers in case of disasters.
What is GPS navigating the land? GPS also improved efficiency on land: delivery trucks can now receive GPS signals and easily transmit their position back to a central dispatcher; police and fire departments use GPS to efficiently dispatch their vehicles and reduced response time; GPS keeps motorists from getting lost by showing their position and intended route on dashboard displays; railroads now use GPS technology in replacing older maintenance-intensive mechanical signals.
What is GPS navigating the air? Long before the GPS, aircrafts typically fly from one waypoint to another and pilots on long-distance flights relied on navigational beacons situated across the country. The dawning of GPS supplemented existing navigational techniques for aircrafts inexpensively. With GPS navigating the air, airplanes can now fly a direct route to a destination that save significant amount in consumption of fuel and time, the methods of guiding planes to a safe landing in a poor weather or visibility has been improved and simplified and aided pilots with a precise position data to keep the plane on course.
What is GPS surveying, mapping the earth, managing the land and agriculture? GPS is used by surveyors and map makers for precision positioning; map locations of such facilities as telephone poles, sewer lines, and fire hydrants; map construction sites and property lines in minutes. In mapping the earth, GPS points have assigned codes in order to identify roads, streams, or other objects during data collection for analyses and comparison through a computer program called “Geographic Information Systems (GIS). ”
GPS can be used in forestry, for mineral exploration, and wildlife habitat management to define positions of important assets precisely and identify their changes. In agriculture, a farm equipment with GPS receivers can provide precise position information and it also gives farmers great accuracy in the application of fertilizers and harvesting crops.
Agricultural GPS systems can be used to create crop yield maps during harvesting, making it easy for farmers to plan exactly how the fields should be used and fertilized for future crops.
So, what is GPS? It is a powerful navigational tool acting as your most reliable and most precise assistant that is transforming the way nations operate in space.

The first thing is to decide how it is with a GPS and the background, what you know about spending on a GPS map. Do you intend to use in your car, for hiking and trekking, or for hunting and / or fish? Current GPS receivers are, what they can do are limited and optimized for a specific purpose. It is specifically for the GPS to fly, others for hunting and / or fish, and others, navigation systems. Some are just an electronic map that shows your position on the map screen. Others have no maps at all and can just as well if you just want to know your latitude / longitude. If you use your GPS in the car plan, there are several options: a basic or mapping handheld receiver, a receiver dedicated automotive GPS with a PDA, laptop or GPS. Although handheld devices can be used in a car, there are some drawbacks, the screen may be difficult to see because of its small size and some units at the front of the dashboard where they can get better signal to be placed. With a base unit (non-mapping) where you can as long as you have to interpret a map with you that data. A mapping unit, the most useful option, taking into account the rule of conduct includes roads. A dedicated automotive receiver is larger than a handheld to a large screen is enough room to see while driving. You are here with the car on electric power systems and for this reason, they can be used in a vehicle. motor units generally allow voice instructions to you without you having to navigate your eyes off the road. Prices start at about $ 500 U.S.. A GPS with a PDA needs to access directly to the sky for satellite reception. Some receivers have built through the antenna or the ability for an external antenna. An antenna on the seat of your car can or not. The console is the next best place – reception, it is doubtful. An Air Vent Mount is better and a windshield or the antenna on the dashboard all the way forward is even better. The most reliable place is to be attached to an external antenna on the roof of your car. A laptop needs a CF GPS with an external antenna, Bluetooth GPS receiver, a receiver-type mice GPS, or connected via a cable to a handheld GPS, so that the recipient is able, for The good reception can be taken. Of course, a laptop is fine, but the main advantage is a very large map display. If you need a laptop in your car, this may be the best choice and a receiver type mice is not expensive. If you plan to use your GPS for hiking or riding, there are three options for receiving a pocket base, a mapping handheld GPS receiver and a PDA. It is also recommended that in addition to your GPS, you must take a paper map and compass, and extra batteries. Weight and height should be considered when deciding to choose GPS. One receiver is the basic mapping capabilities, but it is your position in a format you choose, the display and the most likely latitude and longitude. Providing your paper maps have your chosen position format marked on them, your GPS will allow you to find your location on the map. If your card does not have the position format grids marked already, this is something you’ll want to do themselves. These are the cheaper choice for GPS, often less than U.S. $ 100 and be as accurate as higher priced, they simply do not have much functionality. The main characteristic is that they lack the capacity mapping. For hunting or fishing many handheld models include best hunting and fishing both a place and a specific date. Mapping handheld receivers are often larger, heavier and / or have a shorter battery life than the base units. battery life shorter transport mean extra batteries and apply more weight. With a mapping handheld unit you have the advantage that the maps displayed on GPS. It also includes other benefits as a barometric altimeter, electronic compass, games and a timetable and plan your route in advance on the PC and download them to your GPS. See These units display pre-loaded maps and the map is reflected by the size and screen resolution. This means that mapping units are generally larger than basic units. The downside of a GPS with a PDA is that it can drain your battery faster, and also the top of your PDA. map units are more expensive than basic units, the prices start at about $ 150 U.S. unless you have one with Bluetooth capabilities, which are more expensive. For a fishing chart plotter / GPS or a GPS sounder are also available. The chart plotter / GPS and GPS signals typically have a large number of features and start at about $ 400 U.S..

Currently not enough to just have the GPS, as a fundamental part of its overall performance are the maps which should be compatible with your computer. Please find out about the maps, economic team could buy a GPS and maps for the same price or even more expensive!.

There are already offers GPS with maps already included, it is certainly the best option, to occupy the browser as it gives you full access to their operation and not only your location but you can measure the speed of travel, the coordinates as your location, latitude, longitude, altitude at sea level, you can also take digital compass to guide you, and can choose a point where to go, where the team gives you the option of choosing the shortest route or the fastest This map is drawn in another color to differentiate and estimated time of arrival at destination, taking into account the speed at which it is traveling, in all cases, is in real time by checking your location with a reference point. Another feature is that you can take the view of the map in 2D or 3D, voice navigation (in some this option is enabled only in English) and shows you date and time.

** Additional to the operation of satellite navigator, some teams give you the option to have touch screen, and can be used as text viewer, mp3 player, video player and movies in. avi without needing to convert to other formats and a USB memory stick to store files, very complete it?.

Also you can mark points of interest like restaurants, gas stations, hotels, embassies, parts stores, mechanics, hospitals, information centers, churches, parks, and much more.

So when choosing your GPS, learn if it includes maps, if not bring them, their costs and features, besides taking into account that many cards sd card deal, in which maps are loaded.

Now you can choose your GPS equipment and maps that best suit your needs and make a better purchase.

GPS devices from companies like Garmin, Magellan, TomTom, Navman, Cobra, and Lowrance work anywhere in the world, 24 hours a day in any weather condition. When you buy a GPS device, you need only view of the sky to use it or even need to subscribe to a service.

A GPS device receives data from a network of satellites in geosynchronous orbit around the Earth and uses the information to calculate your precise position. Into three satellites, GPS can tell you your latitude and longitude. With a fourth satellite in view, GPS estimates. Latitude, longitude and altitude.

As there are various systems of measurement, coordinate, etc., once we have our GPS, when we first start to make some adjustments in the menu, some adjustments are to customize the use as user preferences, but where we focus is in the final configuration is to avoid mistakes.

? Datum: This setting arises from the need to distinguish the irregularities presented by the globe by its spherical shape flattened at the poles. For this reason we have to adjust the datum depending on the region of the world in which we find ourselves. In the manuals of the device usually comes a list of all the earth datums.

In the case of Spain, we have two datums, for Peninsula and Balearic European 1950 and the Canary Islands is Pico de las Nieves. There is a universal datum used to the whole planet, WGS 84, Will be the default that comes to our terminal. Although this difference with the previous two is minimal, we will notice some variation.

? Coordinate System:

? Latitude / longitude: This system is the most used, is based on defining a point on the earth’s crust at the intersection of a meridian and a parallel. To express latitude and longitude is in degrees, minutes and seconds or degrees, minutes and decimals of a minute.

? UTMThis form of providing more convenient coordinates, also based on the intersection of abscissa and ordinate, but a number that shows the maps for each grid. We use this system which is used by the military mapping, detailed the method in Spain.

Apart from the definition of a point by the coordinate, THIS (horizontal axis) and NORTH (vertical axis) must take into account the spindle, it is some small parts of the world projected onto flat surfaces (eg, zone 30 in the western half of Spain).

An example of a position by UTM coordinates, would be:

30T 456340 (East)

4778535 (North)

(always the axis This will have a number unless the North axis)

? Units: For our case, of the European units, ie speed in km / h and altitude in meters (decimal metric system).

? Time: We must also indicate the local time difference with respect to universal time, taking into account whether it is winter or summer.

? Language: Interesting possibility that not all GPS offer, especially for those who are not fluent in English, which will surely default.

As we indicated earlier, there are many more adjustments, but the user will decide on their own taste, such as ignition timing light, etc..
