Smartphone dead reckoning that survives GNSS loss. A 240 KB CNN reads vehicle speed out of phone IMU vibration and feeds a Kalman filter with its own uncertainty: 1.5% median drift over 600-850 m outages, 30/30 held-out rides under 10%. Android app, Python engine, and all 71 minutes of ride data. SIH 2026, Team OFFGRID.

Stars, PRs, issues and forks are under-captured in the later part of this window. GH Archive progressively stopped capturing non-push events during 2026 — −95% or worse by the end of the window. Every series here except Pushes fades for that reason, so a decline above reflects the archive, not this repository. Pushes stay reliable throughout, so read them, and the contributor counts derived from them, as the real signal. Data health has the measurements.
Top contributors
Pushes, PRs, issues, reviews and comments — stars and forks excluded, so this is contribution rather than popularity
Nobody pushed, opened or commented here in the loaded window — this repo's activity is stars and forks only.

Totals cover only the window loaded into ClickHouse and count events, not GitHub's lifetime totals — 0 stars here means stars gained during the window, not the repo's star count.
