Before a GPS receiver emits a location (also called a GPS fix), it must receive signals from at least four satellites. The lower the satellite is above the horizon, the longer its signals travel through the atmosphere so satellites high above the horizon usually have better signals.

If there are at least four satellites used in the fix, then you may start using the GPS Essentials features.
