So there is no transmission of any data to the GPS satellites. So the receiver keeps on doing this with multiple GPS satellites until it has enough points to reliably triangulate its location. So knowing the position of the satellite and the time it took for the message to be received after transmission it can calculate the exact distance from that GPS satelliteвЂ™s location to the GPS receiver. The GPS receiver receives the signal, reads the timecode and location in the message and subtracts the time in the message from the current time and gets the exact time it took for the message to travel from the GPS satellite to the GPS receiver. The GPS satellite transmits a radio signal that contains its exact location and the exact time of the transmission. The GPS satellites and the GPS receivers all have very accurate clocks which are exactly synchronized. These transmitters are mounted on low earth orbit satellites. The GPS tracking information displayed on these websites which track the location of the airplanes is not coming from the GPS system.

This is again an example of flat earthers not knowing how things work. The GPS data is being hidden, they say, to cover up the fact that the flight is actually not traveling directly because it would not be possible on their flat earth map. Flat Earthers donвЂ™t understand how Flight Tracking Websites work.ДЇlat earthers claim that because GPS data is missing from online flight tracking services in many cases for these flights in the Southern Hemisphere it is an indication of some cheating. There is a loud explosion, a sonic boom which occurs when the plane breaks the sound barrier, starts traveling at more than the speed of sound, so this sonic boom can not be hidden. To do this on the flat earth map one would need to travel at more than twice the speed of sound for the entire journey. I have personally recently flown from New Zealand to Auckland in a little over eleven hours. These flights would not be possible on the flat earth map so flat earthers try very hard to prove they do not exist. Every day thousands of passengers are traveling to and from destinations in the Southern Hemisphere and reaching their destinations successfully.
