Fixes an issue with coaster filtering

Initial release.

Introduce Android support! Coaster Logger and Coaster Fusion now support Android! Note that quality of tracks from Android phones may vary in quality more than the iPhone counter parts — this is becuase of the hetregenous nature of the Android ecosystem. Further, your Android phone must support the minimum set of sensor requirements — Accelrometer, gyroscope, barometer and GPS. Microphone is optional.

The Attitude and Heading Reference System (AHRS) algorithm has been completely redeveloped, providing better performance consistency across heterogenous smartphone hardware. The custom sensor fusion algorithm handles magnetometer signals more intelligently, especially under challenging magnetic environments, such as launches and break segments. The custom filter also generally behaves in a more stable way under high dynamic conditions.

With the new AHRS changes, you can expect a 5% average improvement in track shape — but most importantly, the worst case scenario can improve by up to 50%. Height and speed estimations also improve in accuracy by 3.6% and 4.7% respectively. Launch and lifthill counts also improved marginally. These values are applicable to tracks measured with iPhones.

Improved handling and warning when there are unexpected gaps in non-inertial data such as acceleration or gyroscope measurements.

Improved coaster trimming heuristics when barometer values are unreliable.

Improved max acceleration and max speed estimations.

Minor performance improvements.

Improved reward function when integrating acceleration information, taking into account barometer information:

• iPhone enhancements, specifically in GPS-denied environments (e.g. indoor rides) (415bfb18)

  • 6% improvements in coaster shape estimation.

  • 4.5% improvements in speed estimation.

  • 7.6% improvements in coaster length estimation.

• Apple Watch specific enhancements (37f150f1)

  • A 42% reduction in the RMSE of maximum height estimation.

• Overall improvement across the entire validation dataset (d8b4305c)

  • General coaster shape expected to improve on average by 3%, with minimal improvements to height estimation (<1%).

  • 3.5% improvement in speed estimation expected.

More tolerant to large and variable gaps in barometer measurements, especially from Apple Watches. However, note that the altitude information will be degraded accordingly.

Enhanced walking detection algorithm to improve recording trimming, allowing the analysis the focus on the true roller coaster portions.

Fixes a critical issue where Watch Only recordings of coasters will not parse at all.

Improved representative point calculation, using all available GPS points during the recording, not just the ride portion.

Fixes a critical issue with Watch recordings exhibiting incorrect altitude fusion due to coordinate system mismatch.
