Can't knowledge How do you know when you are on Google map?
You may have seen Google May 5 on a smart phone or an elderly man in your house. Its advertisement comes on TV. Wherever you are from wherever you are on Google Maps to go wherever you want to reach, the way forward from where you stand is going to appear on the mobile screen. If you touch the button of the audio, the sound of the woman is going to be 400 meters forward and you have to turn left. Instructions to move from front to right or to the left are forwarded before you go ahead and you reach wherever you are going!
The biggest question is, how do you know exactly where you are standing right now?
The answer is, from GPS! GPS means Global Positioning System. This system has been created by America. In it, there are 30 satellites in the sky, which are 20,000 kilometers above the earth, which are rotating around the earth. This system was originally designed to keep an eye on communist enemy countries of America.
Google map has been created with the help of these satellites. Not only in cities or villages, details of the city or village buildings, temples, roads, hospitals, shops etc. have been recorded. If the new roads or buildings are built using satellites, the map automatically improves.
This map is in every satellite. Each satellite continuously sends the radio signal to the Earth. The signal is in our phone. In response, our phone is constantly sending radio signals. It flows into the satellite. Where is the signal from our satellite that we get to know the basis of Google map. Each satellite has a real-time clock. It can measure the time in milliseconds.
By checking how many times your mobile signal is detected, the satellite determines exactly where you are. After knowing the time of how many times your signal was received from the surrounding three satellites, it accurately determines where your mobile is located. Based on this, it shows you the way and what buildings and vehicles are located around.
