If we lose the forest and can not distinguish the direction of the wind can still be accepted, see if the city we can be lost even if it can be said, this news is so ... especially if we want to visit an important event or just berekreasi while eating at a place and time is only meters away from one place to another without finding a place dituju. GPS or Global Positioning System may be an alternative solution the problem. If you hear the word GPS device certainly be a sophisticated and expensive and its use is very complicated, but the new generation GPS at this time is not that expensive, exclusive and more complex but have penetrated to the tool in the small and simple, easy to use, including a mobile phone with some completeness a certain type. Why do I have the GPS, what is there and how does it work, that this may always be the question before deciding to buy the GPS as a tool bantu work. GPS is a navigation system that uses a network of 24 satellites orbit the earth orbit and provide accurate data about a particular position on the earth. Satellite-satellite this is controlled by the Department of Defense and the United States was used to bolster their air defense system. The first GPS satellite was launched in 1978, and grew quickly and eventually to operate 24 satellites the first time in 1994. Satelitnya every age about 10 years so that the renewal should be for the satellite had been the pensiunnya.United States government finally allow use of satellite navigation system to the public because of the benefits that can be very large and able to work in all circumstances for 24 hours without stopping and without fee or charge is also the
How GPS Work
Each GPS Satellite circumnavigate the earth as much as 2 times in seharinya in a very precise orbit and transmit signal information to earth. Tools GPS Receiver Signal after receiving signals from satellites ago comparisons with the situation when the signal is sent. Dikalkulasikan the time difference is how far into the distance when the satellite signal is received. With the position signals received from several satellites, the GPS signal Tools Recipients can determine its position at that time which are then displayed in the LCD screen is informative. GPS Signal recipient must not lock the signal from 3 satellites to calculate the 2D position [latitude and longitude] and speed of movement. Utilizing satellite signals from 4 or more users can get the GPS position data to 3D [latitude, longitude and altitude], the more subtle satelitnya the data that can be converted into images for display and the higher the accuracy of the data. After the GPS user's position can be determined, the GPS Receiver can calculate and provide information about speed, direction, distance from a point ketitik and many other info, such as POM Gasoline, House, including whether to eat or have a bridge where the nearest police station.
How akuratkah data that we receive in GPS Receiver
Currently, the GPS data in the recipient we can very accurately because it spelled out in the system of GPS receiver can lock multiple parallel signals with a position accuracy of an average 15 meters around us even though many concrete buildings or buildings higher. 24 GPS Satellites to mengorbit own the earth with an altitude of around 12,000 mile, constantly moving with the speed of approximately 7000 mile / hour 2 times around the earth within 24 hours. GPS uses satellites Solar Energy with batery backup when there is no sun and use the rocket to control small satellites remain on the correct path. GPS satellites emit signals, known as L1 and L2. General path using GPS L1 frequency 1575.42 Mhz around [UHF] and the signal type "line of sight", can penetrate clouds, glass and plastic but can not penetrate anything solid, such as buildings or mountains.
GPS Receiver Signal Products.
Currently, many brands are sold dipasar GPS, more than 30 outstanding brand GPS dipasaran the world, at this time there are some who can didaptkan in Indonesia, among other brands such as Garmin, Mio, and other Shinco. The progress of technology with both hardware and software and communication devices make the GPS into the form of tiny and light brought. Mio DigiWalker C-230 can be an example of how GPS is so easy to find the backpacker way a particular purpose, this is seen from the Digiwalker name. megunakan CPU Samsung 2443-400Mhz, LCD 3.5 "320x240 pixel, 20-channel GPS receiver, touch screen, Software VioMap V3, Battery can hold up to 2.5 hours so that friends can be a trip. When you bring a car, have the adapter to connect to the battery lighter socket. Mio C230 is very fast to receive satellite signals to determine the initial position when the device is turned on, and we live determines the starting point [destination] and our goal is, then you will "dituntun" to place by the "Mio" is. Mio C230 has been able to bring you around Pulau Sumatra, Java and Bali .. the distributors are arranged to add kebeberapa other locations in Indonesia.
