We live in a world of advanced technology. Every day new gadgets get invented for making things easier for us. One of such inventions is the GPS. We know that some devices use satellites to find the exact location of an object on earth. However, do you know how GPS works on your phone? The full form of GPS is the Global positioning system. It does not link with the satellites rather they take data from it from the users. Mobile users utilize it to determine the location. That is why it is an important addition to a mobile phone. Here are some details about it that will interest you.
Know how it works on your mobile phone here.
Let’s understand what GPS is
It is a system that consists of satellites, receivers and ground stations. The people of the ancient and medieval eras used stars to find the location however today we use the satellites to determine the location. The ground stations utilise the radar to find the location of the mobile user. Then the receiver in the phone always listens to the signal from the satellites. Some rapid calculation happens to determine the exact locations.
The origin of GPS
The GPS got created at first for use of the US military. Later it became used by civilians too. There are twenty-four GPS satellites roaming around the earth’s orbit and they are always giving out a lot of data. The satellites arranged neatly around the orbit to give out signals without any disruption in the middle. Moreover, the GPS satellites give out radio signals to the earth. The transmissions contain the location of the satellite as well as the timings of each signal. The timekeeping is very exact as there is an atomic clock onboard available in it.
How GPS finds out the location?
A smartphone has an inbuilt GPS for determining the location of the user. But these devices do not link with the satellites to determine the locations rather they take the radio signals that the satellites give out. The GPS receiver will accept the signals from four or more satellites. The satellites that are closer will give out the signals more quickly and then the others will arrive after that. Then by utilizing the method of trilateration the receiver will know the location.
This is a method used by the GPS to know the location because if it understands the distance you are from four different cities then your location is easy to find. This is how the GPS determines the location every time.
GPS in modern-day life
GPS has become an important part of our life. It is easy to find out the locations of the nearest restaurants or hotels on your phone because of the GPS. It has made travelling easier as you can reach your destinations without getting lost. That is why many people find the GPS in their smartphone very useful.
This is the way how GPS works on your mobile phone. Use GPS and make your life easy.
