Ultra Low Power - High Accuracy Location for Wearables

Steve Malkos and Manuel del Castillo, Steve Mole

Abstract:	End-users were first exposed to the amazing capabilities of GPS 12 years ago with the first mass- market GPS devices. The focus was on navigation applications with specific tracking devices like PNDs (Personal Navigation Devices) and PDAs (Personal Digital Assistants). Soon, with the advent of smartphones, GPS became a must-have feature. Other constellations started to be added to improve performance: Glonass, QZSS, SBAS, and very recently, BeiDou. In this current phase of the GNSS industry, the focus is shifting to fitness applications and background location. This is not an insignificant change. Always-on connected applications, high-resolution displays, as well as other useful features do not improve battery life. In this article, we will see how new Ultra–Low Power and High-Accuracy Location solutions for wearables address this power consumption concern.
