There is a specific method for determining the location of your cell phones using a method known as triangulation method or also known as triangle measurement. What is a triangulation method? If you've seen a lot of CSI episodes, you probably know what a method is. This is basically a method of determining the location of cell phones by measuring angles to it from certain known points or a fixed baseline. By specifying the speed of the radio signals, the distance and location from an unknown point can be estimated by identifying from three to four known points. Known points may be antennas for a cell phone operator. The first known point identifies the distance to the cell phone. The second known point then narrows the place to two points. The third known point is then used to determine the exact location of the cell phone. In principle, the concept narrows down the exact location of a cell phone, eliminating a large area of a certain place to accurately determine a location using three filters or three known points. Two lines of direction define the point zone, and the third line defines the exact location.
In principle, the basic principle in GPS is also to use triangulation to determine the highest possible accuracy of a point in space. The triangulation method uses three coordinates or three GPS satellites from a user's GPS receiver. From the distance measurement of these three coordinates, the user's location can be determined by determining the intersection of the three satellite coverage areas. The more GPS satellites it reflects, the more accurate the position it can determine.
We will witness more hardware and software that will be developed to further help people in terms of connectivity and mobility based on this triangulation method. Social media will benefit from this, as the flow of information will be transmitted through this medium. One example of a Social Media platform using this method is the Foursquare app. Established in 2009; The app serves as a location-based social networking platform for mobile users. Users can register their current location or hangout and at the same time give feedback on the location or product. Users can also use this app to connect with friends nearby. As the Internet mobility technology becomes much more complex, it is expected that many location-based social networking platforms will also be developed. Some of the well-known location-based services are Foursquare, Loopt and Google Latitude apps provide you with a real-time place for friends who choose to share their location with families and close friends. At the same time, these apps also share information about the whereabouts of their friends or families, such as restaurants, where they have lunch, or about the place where they hang out.
However, the triangulation method has its drawbacks, such as obstacles that will prevent your GPS from detecting three satellites when you are inside a building, close to a tall building, and bad weather. This factor blocks the line of sight of your GPS and there, before it can find the three satellites needed for accurate positioning.
