Gyro White Noise Simulation:
A static vehicle is located at 45 degrees north latitude and is pointed north. Gyro white noise with standard deviation of 0.01 degree/root-hour is placed on the east gyro only. Position and velocity errors grow as expected:





Pitch error is quite noisy which is to be expected since the vehicle is pointed north and thus the east gyro directly affects pitch. Roll and yaw errors are smooth since they are affected indirectly by the east gyro error:




Yaw error experiences a drift in addition to the Schuler oscillations:
