Google Smartphone Decimeter Challenge

Swift Navigation is pleased to be an authorized corrections provider for participants in the 2021 Smartphone Decimeter Challenge held by Google and ION.

To assist research teams participating in the challenge, Swift is providing corrections from its Skylark Precise Positioning Service as part of the pool of datasets aiding teams competing to achieve the highest-accuracy GNSS positioning on smartphones.

  • About the Challenge

    Google and ION are encouraging the GNSS community to develop high-precision GNSS positioning applications on smartphones. Teams who have submitted the required abstract will compete to achieve the best location accuracy with the provided datasets.

    Google and ION are contributing resources (including Swift’s GNSS corrections) to researchers and academics to spur development of algorithms that will improve the accuracy of smartphone location solutions from their current multi-meter levels to, ultimately, a tenth of a meter or better.

  • Corrections Data

    As part of the second set of data provided for this challenge, Swift’s corrections data can be accessed on GitHub here and is available in both state space representation (SSR) and observation space representation (OSR) formats.

    The Swift test team continually tests its products by conducting drive tests to ensure Swift's ecosystem of products demonstrates the performance customers expect across environments.

    This supplements the smartphone measurement data provided by Google at the onset of this program.

  • Swift Precise Positioning

    Skylark is a wide area, cloud-based GNSS corrections service that delivers real-time, high-precision positioning. Skylark uses patented, cutting-edge positioning algorithms to provide a continuous stream of multi-constellation, multi-frequency GNSS corrections.

    Skylark delivers a continuous stream of robust, reliable, multi-constellation, multi-frequency corrections with initialization times measured in seconds—eliminating long wait times for initialization and reconvergence.

    This data stream is delivered to devices across continents via Internet connectivity—unlike legacy systems that leave users tethered to fixed base stations or local CORS networks.
