SUMMARY

This discussion focuses on calculating gyro outputs from aircraft attitude and movement data, specifically using roll, pitch, and yaw angles and rates, along with xyz accelerations. The user seeks to back-derive the x, y, and z outputs of a simulated gyro installed on an aircraft. The methodology involves drift correction, matrix transformations, and Euler angles to recreate the aircraft's attitude and rates. The user aims to validate this mathematical approach through simulated flights.

PREREQUISITES
  • Understanding of roll, pitch, and yaw in aircraft dynamics
  • Familiarity with Euler angles and their applications
  • Knowledge of drift correction techniques in sensor data
  • Experience with matrix transformations in 3D space
NEXT STEPS
  • Research methods for implementing drift correction in gyro outputs
  • Explore matrix transformations for 3D rotations
  • Learn about Euler angles and their conversion to quaternion representations
  • Investigate simulation tools for testing aircraft dynamics, such as X-Plane or FlightGear
USEFUL FOR

Aerospace engineers, flight simulation developers, and anyone involved in aircraft dynamics and sensor fusion will benefit from this discussion.

If I have roll pitch and yaw attitude of a plane, and roll pitch and yaw rates relative to Earth frame, and xyz accelerations on the pilot, how do I back-derive the x y and z outputs of a pretend gyro installed on said plane?

The forces the gyro will report will not be the the roll pitch and yaw rates relative to the earth, I've got some math that uses drift correction, matrices and euler angles to take this gyro output and re-create the roll pitch and yaw attitude of the plane along with the rates they are changing and I want to test the math out in simulated flights (the sim being the one that provides the numbers I mention in paragraph 1).

thanks
