The Institute of Navigation’s Satellite Division and Google are hosting the 2nd Smartphone Decimeter Challenge

Manassas, Virginia –The Institute of Navigation’s Satellite Division, in partnership with Google, will host the 2nd annual Smartphone Decimeter Challenge with the winning teams presenting their methods at the ION GNSS+ 2022 meeting, September 19–23, 2022, at the Hyatt Regency Denver (located adjacent to the Colorado Convention Center), Denver, Colorado.

The Smartphone Decimeter Challenge is designed to advance research in smartphone GNSS positioning accuracy using state of the art algorithms and technologies such as advanced machine learning models and precision GNSS algorithms.

While standard GPS and other GNSS (Galileo, BeiDou, GLONASS, QZSS, and IRNSS) receivers provide accuracy between three and 10 meters (often worse in urban environments), better location can be obtained by processing carrier phase measurements, IMU data, and base station corrections.

Teams will use data-sets collected using GPS and inertial measurement units (IMUs) of Android smartphones to compute location down to accuracy of decimeters. Mobile users will benefit from lane-level-accuracy based services, enhanced experience in location-based gaming, and greater specificity in location of road safety issues.

Winner selection is based on the accuracy of results from the test datasets compared to highly accurate ground truth. The top three winners will receive prizes valued at $15K+ that includes: a guaranteed speaking slot at the highly competitive ION GNSS+ 2022 conference (subject to technical paper and ION presentation requirements); travel subsidy; and complimentary registration to attend ION GNSS+ 2022 in Denver.
