Smartphone Decimeter Challenge 2023: Workshop for Benchmark Competition
Sponsored by Google


The goal of Smartphone Decimeter Challenge  is to compute smartphones location down to the decimeter or even centimeter resolution which could enable services that require lane-level accuracy such as HOV lane ETA estimation. Solution will be developed based on raw location measurements from Android smartphones collected in opensky and light urban roads using datasets collected by the host.

Google will launch the 2023 Smartphone Decimeter Challenge (SDC) competition at the ION GNSS+ conference itself.
