Most people misjudge it that the GPS global positioning system function is only used for car navigation, such as gps navigation dvd player or portable gps navigator. In fact, GPS system pervades our daily lives. From communications to electric power, GPS system is playing its most important use of accurate timing. Through the accuracy of the timing accuracy to synchronize the system time to ensure that some of the facilities in everyday life is normal operation. Of course, the most widely used and the largest number of an application is car navigation, but it definitely does not represent the highest.value of all applications is car navigation. The underlying applications for GPS as follows is equally important:
1. Golbally Uniform Time to Ensure More Just Financial Transactions
Communication systems require precise timing, so as to distinguish between different communication systems to receive and send information without confusion, reduce the system pressure, the financial system is the same, if there is no uniform time for global financial institutions, then the reliability of financial transactions will be greatly reduced.
2. GPS Coordinates Is One of The Most Accurate Information When Provide Disaster Relief
Coordinates of the points on the planet is unique, so once we know where the coordinates we locate, then it is very helpful for a lot of things. Correspond with the rescue, a precise location can make aid more efficient, rapid and accurate. As long as needed positions, needless to say, GPS satellite positioning is certainly the best choice.
For example, where the earthquake occurred, when the tsunami arrived, through GPS positioning, these data can be more accurate in front of us. In addition, some simulated disaster system also need such accurate data in the process of calculus. GPS positioning is a very good tool in this respect.
As a result, when driving to tourism in an unfamiliar places, remenber to install gps navigation system for your car, or bring with a portable gps navigator for a picnic in the field as far as possible, which is a protection for your own security in cases of emergency, and under the circumstances, GPS positioning coordinates to become a very efficient rescue data.
3. To Detect Earth Movements with GPS System
GPS is widely used in the detection project of earth movement. According to high-precision measurement on the earth movement report in Science magazine, through the installed PBO (Plate Boundary Observatory) receivers in the western United States Boundary Observatory, researchers can observe the tides, and they can infer, including Plates displacement, earth movements, even accurate to the millimeter.
It is not difficult to find that we can find traces of GPS satellite positioning, as long as we need to determine the location. And GPS system is gradually starting to enter into our daily life among the necessary facilities. That is to say, the strategic significance of GPS satellite navigation is not just limited to military purposes, but more is to protect this infrastructure to the normal and efficient operation, consequently, so many countries are beginning to establish their own satellite navigation system.
