Thanks to GPS, you can determine your exact location at any time and in almost any place. Position determination is the basis for other functions (such as map display and routing).
GPS (officially NAVSTAR GPS) has been available for civilian purposes with high accuracy since 2000. In addition to navigation in cars, the system has also established itself in the outdoor sector for hikers and cyclists. Garmin is the market leader for classic outdoor GPS handheld devices.
Since 2010, there have been Android smartphones and austria gambling data iPhones with integrated GPS receivers. The trend is currently in the area of 'sports and training' with fitness trackers and GPS watches. In addition to the American version, GPS devices and smartphones now also access other global navigation satellite systems, such as GLONASS and GALILEO, so the umbrella term is GNSS or 'Global Navigation Satellite Systems'.
With NAVSTAR GPS, around 30 GPS satellites orbit the earth. They send out signals. GPS receivers compare the time at which this signal was sent out with the time when the signal arrived. The distance of the GPS device from the satellite is calculated from this time difference and the position of the satellite. If you now have signals from three satellites, you can determine the position. However, reception is only accurate to within 5 m from four satellites.
