    How to get one-meter location-accuracy from Android phones
    Recent changes in industry standards and practices enable up to 10x location-accuracy improvements. This talk explains when and how developers can get or create high location-accuracy from Android devices, going over timelines, technology, and API details. This includes outdoor location (based on GPS) and indoor location (based on WiFi). The talk includes high level explanations of carrier-phase positioning with GPS, and RTT positioning with WiFi. It features a video demo of a person navigating indoors using an Android phone with WiFi RTT location.

    Frank van Diggelen is a Principal Engineer at Google. Previously, he and a small group of friends created technology that put GNSS in smartphones. At Global Locate, a GPS startup, they built the Assisted-GNSS chips and technology that started a location revolution. Their chips were the first GPS in any smartphone, the first in iPhone, the first GPS+GLONASS and the first full GNSS (GPS, GLO, BDS, GAL, and QZS) in phones. Frank has over 90 issued US patents on A-GNSS, and is the author of the textbook: “A-GPS”. He received his Ph.D. at Cambridge University, he teaches part-time at Stanford, and works full-time at Google where he leads the GNSS team for Android. He is the Chair of Satellite Division of the Institute of Navigation (ION), and is a Fellow of the ION and the Royal Institute of Navigation.
