GPS satellites continuously send different information through the RF frequency band. For example, satellites are equipped with extremely precise atomic clocks. GPS satellites send information about the time on their atomic clock, as well as their orbital position and arrival time at different points in the orbit. The GPS receiver uses this information to calculate its distance from the satellite. If the distance between an object and three fixed points in space is known, the absolute position of the object can be found. Therefore, the GPS receiver can find its geographical location by calculating the distance to three satellites. However, at least four GPS satellites are required to accurately locate the time and location. The distance from the fourth satellite is used to compensate for the time error of the GPS receiver clock. So, the GPS receiver calculates its geographic location by calculating its distance from three GPS satellites, and uses the distance from other GPS satellites for correction and accuracy. If the receiver can see at least 4 GPS satellites, it is said to be in a locked or positioned state. By calculating the distance from at least four satellites, the GPS receiver can accurately locate their geographic location (latitude and longitude) and current (UTC) timestamp.
enhance
GNSS enhancement is a method of improving the accuracy, reliability, availability, and other attributes of navigation systems by integrating external information into location calculations. Some enhancement systems include: Wide Area Augmentation System (WAAS), European Geostationary Navigation Coverage Service (EGNOS), GPS Assisted GEO Enhanced Navigation (GAGAN), Differential GPS, Multifunctional Satellite Augmentation System (MSAS), and Inertial Navigation System (using accelerometers and gyroscopes).
