HOW GPS WORKS
HOW GPS WORKS GPS IN DAILY LIFE WE USE GPS FOR ALL LITTLE THINGS BUT WE DON'T KNOW HOW ITS REALLY WORKS SO HERE WE GO WITH FUNCTION WHICH MIGHT IMPROVE YOUR KNOWLEDGE. FULL FORM OF GPS GPS- GLOBAL POSITIONING SYSTEM HOW gps works A GPS receiver must be locked on to the signal of at least 3 satellites to calculate a 2-D position (latitude and longitude) and track movement. With four or more satellites in view, the receiver can determine the user's 3-D position (latitude, longitude and altitude). GPS satellites circle the earth twice a day in a very precise orbit and transmit signal information to earth. GPS receivers take this information and use trilateration to calculate the user's exact location. Essentially, the GPS receiver compares the time a signal was transmitted by a satellite with the time it was received. The time difference tells the GPS receiver how far away the satellite is. Now, with distance measurements from a few...
