Tracking Large-scale Shared Bikes with Inertial Motion Learning in GNSS Blocked Environments

Dimensions overall score 6.0

• An inertial tracking framework for large-scale shared bikes that integrates mechanical constraints with a mixture-of-experts model for accurate localization in GNSS-denied environments. Despite decades of research, localization using only low-cost inertial sensors still faces challenges such as cumulative drifts and poor robustness caused by filtering methods.problem 35%

• ScienceToStartup currently rates this 6.0/10 on the public viability pass. Experiments with real-world riding data from shared bikes of the DiDi ride-hailing platform demonstrate that our system improves the accuracy of baselines by at least 12%, with wheel speed errors below 0.5 m/s at 95-percentile. Code availability is flagged in the production record; the public repository link still needs proof alignment.result 35%
