EASY™ is the abbreviation of Embedded Assist System that for quick positioning, the GPS engine will calculate and predict automatically the single ephemeris (Max. up to 3 days) when power on, and save the predict information into the memory, GPS engine will use these information for positioning if no enough information from satellites, so the function will be helpful for positioning and TTFF improvement under indoor or urban condition, the Backup power(VBackup) is necessary.

When GPS device gets the satellite information from GPS satellites, the GPS engine automatically pre-calculate the predict orbit information for 3 days. The GPS devices still can quickly do the positioning with EASY™ function under weak GPS signal.
