Abstract

NIST carried out comprehensive testing in five large buildings to evaluate the accuracy of Fused Location Provider (FLP) Application Programming Interface (API) running on Android phones with that of Core Location Framework running on iPhones. The testing was done under various mobility modes using the performance metrics provided in the international standard ISO/IEC 18305. The paper presents the results of these evaluations for horizontal, vertical, and 3D errors. Even though in some cases and respects Core Location is better than FLP, it can be said that FLP has overall better accuracy than Core Location. One area where Core Location is better is in that it consistently provides location estimates at a fast rate, while FLP provides location updates at a slower rate and sometimes it does not provide elevation information. The paper also compares the accuracy of FLP with that of the top Android app that won the PerfLoc Prize Competition organized by NIST for developing Android indoor localization apps.
