GPS| GPS navigation| Tracking your global position with a GPS navagation receiver unit
GPS is basically a global positioning system used to locate a GPS receiver, which will receive in three-dimensional space anywhere you might be on earth. GPS is controlled by 21 active orbiting satellites at almost 12000 miles above the Earth. The GPS navigation system is designed to have multiple tracking satellites at any given point on Earth. Ground control stations and spare satellites complete the full global tracking system. GPS navigation is probably one of the most astounding inventions to help mankind in so many different applications. An example of GPS you might not have thought of is parcel tracking delivery by truck, ocean liner guidance systems, airlines right down to hikers to golf cart GPS.
The reason GPS navigation is so widely used is because of the very rapid and high degree of accuracy, which can be used in all weather conditions and any time you need it no matter where you are on earth. With the use of transmitted radio signals from satellites your GPS receiver has the ability to find your position within 50 feet (15 m). GPS software is used to take the information and evaluate the position of the GPS receiver.
There is a very basic principle that is used from the receivers that is it reads signals from multiple satellites and places at least three positions on the ground taking a barring and draw a line through three points then you'll know exactly where you are globally positioned. There are a few limitations that may hinder your calculations. First the GPS navigation receiver should have a clear view to the sky in order to receive data. Radio microwave signals travel in straight lines just the same way light waves do. You will find anything solid will block your signal such as a canyon walls or even trees. Any weather conditions like snow or rain will not interfere with a satellite signal.
How does GPS create global positioning?
The GPS navigation unit is all based on precise time measurement. All satellites that are used for GPS positioning and tracking have several atomic clocks on board their systems. It all starts with the satellite transmitting exact time radio signals that your GPS receiver will pick up on. The satellite radio signal delivers precise time to information, giving the GPS receiver exact timing when the satellite sent the signal. The GPS navagation unit onboard computer uses this measurement of time in transit, at the same time the satellite will send a transmission navigation signal and will tell the GPS software their exact position.
With this information in your GPS receiver it will calculate the distance from the satellite and give you your GPS navigation system location on a spherical surface. A GPS device then links to more satellites and will complete the same procedure where the three points meet and show where the GPS navigation unit is positioned. By acquiring a signal from a fourth satellite will just refine your global position.
Things to look for when choosing your GPS navigation unit
-
Signal loss: this is that big problem that you should ask about. Forest and canyons and caves will hinder your readings. You can keep this to a minimum if you use a system that continuously monitors several satellites at a time.
-
GPS software: check to see what the gps navagation software is capable of. Is it good for mapping, is it cost efficient, will the program lasts for more than five years.
-
GPS power supply: check on battery life to use as their unit is draw and will use a lot of power if left on continuously. Check to see if it is AC adapter compatible.
-
GPS/maps/directions: check to see the GPS mapping capability and displaying cleric tee of the unit. Will it be able to use old mapping from your PC. If you travel a lot see if it's compatible outside your country. Ask is this mapping system will last at least five years as markets change rapidly.
-
GPS and durability: check to see if they unit is waterproof. Also look at the shockproof design to see how rugged it is. Check on temperature limits as some systems don't work well under extreme conditions.
What are a few areas of the uses of GPS navigation?
There are several different uses that you could use a GPS unit. On the road in a car, hiking the wilderness out of the water or even in the air. All of these areas can be sub categorized to more specific uses depending on your specific GPS needs. Looking for a car GPS realize that these units need to have some reasonable accuracy and be reliable. They must contain road maps detailing areas that you want.
Remember the satellite is only used for timing and transmitting of global positioning data and don't send actual maps data, that is up to your GPS navigation unit to calculate. There are portable GPS devices that you can quickly install in the vehicle for the same use. You can always acquire a handheld GPS unit and be portable and on the move anywhere you need to be. One more is the maritime GPS which uses very specific mapping software programs because it needs to use information differently it also should be waterproof.
