The Global Positioning System (GPS) was created by the UP Department of Defense to respond to the second most important question of the army, "are you?" Location "(The most important question is:" Where's the chow line? " )
Today, GPS satellites transmit signals continuously earth-Ward, who had position signals from GPS receivers calculate. It was not until police and firefighters, construction workers and other civil workssee the value of GPS.
Consumers, the industry needs to refine the GPS electronic tracking system in user-friendly, consumer. For example, it is good to know little, you're at 40 degrees 33 minutes 24 seconds North 118 degrees 48 minutes 36 seconds after the West unless you already know that there is Overstock.com and you try to access the parachute on the roof of the office. For example, manufacturers are away from visual directions.
The Global Positioning System hasthree areas:
Satellites
Twenty-four active standby and five satellites orbit the earth twice a day. At least four should be "visible" to the ground at all times, are derived, GPS tracking system users with the exact latitude and longitude and height.
Command and Control System
Currently, under the direction of Air Force Space Command, some areas are managed by other agencies Center, as the Coast Guard Navigation (for seafarersExpenditure).
GPS Receiver
GPS devices are one of the electronic receipt, which does not transmit data or interact with other sectors of the system. This allows an unlimited number of concurrent users. In other words, this may be the only thing the U.S. government, which is available 24 / 7 and never put on hold!
Consider using it to buy a GPS device:
GPS
The most popular application, GPS devices for cars are all the road maps;high-end models offer voice guidance turn-by-turn. Ruffles are touch-screen, mobile connectivity, video games, radio, CD or DVD player and computer connections to obtain software updates.
Cell Phone GPS
Mandated in the wake of September 11 called for '(FCC) Federal Communications Commission cell service, GPS tracking cell phone calls to make this possible. All phones are manufactured from 2005 GPS-tracked. Mobile phones with GPS receivers are portablealso present, but may not function properly if they are outside your local cellular service provider.
Recreational GPS
Wrist, hand and wrist GPS devices are ideally suited for walkers and cyclists.
Marine GPS
Marine GPS course, is water resistant (most electronics do not react well to water!) And float - is not a feature you want to actually use, but the most extreme circumstances should welcome occurrence. Ocean maps are notoriously boring to read, but the graphs and coastal featuresas tide tables and fish-finder can be very useful. Marine GPS tracking is particularly useful when entering or leaving the ports crowded.
Accessories and add-on to increase their use GPS:
Maps
GPS devices are factory-installed maps of the United States. Globetrotter, more GPS Maps of Canada and in other areas.
Data Storage
GPS users can save even more if the device supports removable memory cards, as is normally used forDigital cameras.
Combo Pack
For most people, a lot of work on their own GPS receivers. For the serious user / traveler, portable GPS devices are available, equipped with personal digital assistant (PDA) and two radio As already mentioned, the GPS devices can also drive or extra entertainment media.
GPS Holder
These attach to the dashboard or console to a handheld GPS should not be hand held while driving.
GPS Antennas
The GPS signals are reinforced andparticularly in urban areas where there is still the possibility of interference from terrestrial sources.
GPS Chargers
Obviously, a portable GPS to charge home and car adapter available.
Some GPS Terminology:
Nationwide Differential Global Positioning System
The commercial GPS receivers are almost always a sign within about 50 feet, but many users will see accuracy within 30 feet. NDGPS is a common transport-Commerce Homeland SecurityProgram with fixed, ground reference stations. If near a marker NDGPS GPS precision of less than 10 meters to increase.
Geocaching
Geocaching (pronounced / GE-oh-cash-re /) is an exciting new and gaining popularity every year - a sport that exercises both body and mind. In a nutshell, is looking for GPS-N-Hide; player objects the size of a 35mm film can in a box of military ammunition in plain sight. The locations (latitude and longitude) are connected to the WebLocations. Players use their GPS devices to locate the cache or "waypoint". There is a lot harder than it looks. Waypoints can be plants or stones can be camouflaged in and get a lot of ground to cover from 30 feet. Some stages are pick-n-place, which means they have prizes inside, if you find one, the trade a piece of jewelry to wear a piece of jewelry that you find.
Benchmark
A means of early determination of the location marker was metal from the Department of Commerce NationalGeodetic Survey (NGS). These are still available and can be found anywhere in the U.S. on street corners, peaks, parks and other places obvious and not so obvious. All reference sites are registered and the NGS. You can do a quick test to see if the GPS device is working properly, or for geocaching.
Question - can the government really haunted me through my mobile phone?
Not only the government, the GPS tracking via cell phone to a commercial service availableParents (one for their children) than others, entrepreneurs, and (for vans and track employees) (also pet owners can hook up a GPS receiver, their pets, Rover lives up to its name). Safety, quality of service and fraud have been recognized by the courts as a legitimate use of GPS tracking systems for monitoring non-governmental organizations.
GPS tracking abuse and abuse are inevitable, but that applies to all modern comforts's - for the positive aspects of GPS, there arealso some disadvantages. However, it is the day your son, daughter, or the load is $ 100,000 of other property missing, I am not crying "invasion of privacy!" the FCC.
Caring for GPS devices:
Dust, heat, humidity and shock are the main causes of failure. Let your GPS device, even on something as soft as the water - especially on something as soft as water!
Wipe with a cloth before him away, and if your GPS receiverAperture, a data card slot and battery compartment, as blow clean with compressed air from a can - it is never humid breath.
If you have a GPS system for same car hanging out of direct sunlight. Even in the cold days, the dashboard to get dangerously hot for electronics and excessive radiation from the sun can damage your memory - yes, sunburn can be connected to a GPS terminal to be.
Like all modern consumer electronics, has to break a GPS receiver, only a few moving parts so it canvaluable services for years (and a lot of fun!), if not abused. Have fun!
