Inside TetraAxial

What it does

Sensor capture

IMU at 100 Hz, ARKit 6DOF at 60 Hz, GPS, barometer and LiDAR — synchronized and frame-accurate.

OSC streaming

Real-time UDP streaming of /accel, /gyro, /attitude, /arkit, /gps, /baro and /timecode to your receiver.

Timecode sync

MTC, LTC or Device Clock, interpolated to your project framerate — including true NTSC 23.98 / 29.97. Honest sync status, never a false lock.

Calibrated export

Camera-relative calibration with a ±2° horizon level-lock, and synchronized dual-file CSV export with full session metadata.
