Reference Design of the Power Management and Signal Treatment of a dedicated Global Positioning System (GPS) Tracker based on Nexperia Solution. a dedicated GPS tracker is the better option - especially for hikers and others in remote locations where accurate location data is essential. Whether handheld or wearable, these devices incorporate an increasing number of features - including including navigation, way-finding, real-time route tracking, and topographical maps - and can often track speed, distance, and altitude, recording vertical gain and loss along the way. As with all mobile devices very efficient power consumption and space-saving packaging are vital. This design balances extremely long battery lifetimes with always on functionality, provides low power dissipation and uses smaller packages or wafer-level chip scale footprints.
