dynamics matrix, Γc is an input matrix, δu is the unknown accelerometer and gyro biases vector, and w is a 38 Brownian motion vector (which quantifies...velocity over a flat and non-rotating Earth. Therefore, the only true dynamics of the simulated aircraft is the movement in the x direction. This... movement is due to the aircraft’s constant velocity, which directly relates to the true aircraft position. Therefore, the output of the Free INS is
