Slide 11: Self-AGPS EASY Technology(1)
Self-AGPS EASY Technology(1) l EASY™ is the abbreviation for Embedded Assist System for quick positioning. With EASY™ t e technology, the GNSS engine can calculate and predict automatically single ephemeris ( up to 3 days) l when the power is on, and then save the predict information into the memo
Slide 12: Self-AGPS EASY Technology(2)
Self-AGPS EASY Technology(2) TTFF Comparison t e l l e c t i a u n Test Condition TTFF without EASY™ TTFF with EASY™ Q fide Cold Start <35s <15s Under GNSS signal Generator, n conductive power level -130dBm o Warm Start <30s <5 s C With EASY™ technology, L76 accelerates TTFF obviously.
Slide 13: Periodic Standby Mode
Periodic Standby Mode Periodic standby mode can control power on/off time of GNSS periodically to reduce average power l consumption, and on/off time can be configured by using PMTK command. For details, see the figure below. e Periodic standby mode can be entered by sending the following PMTK comma
Slide 14: AlwaysLocate Technology
TM AlwaysLocate Technology e l AlwaysLocate™ is an intelligent controller of periodic mode. ct a l L76 can adaptively adjust the on/off time to achieve balance between positioning accuracy i and power consumption according to the environmental and motion conditions. So the e t average power consum
