The azimuth estimation apparatus includes a processor performing a plurality of operations including: acquiring acceleration values, angular velocity values, and geomagnetic values in different directions while the azimuth estimation apparatus rotates at a first location; acquiring a rotation angle value of the azimuth estimation apparatus based on the acceleration values and angular velocity values; acquiring sampled geomagnetic values by sampling the geomagnetic values based on the rotation angle value; estimating an azimuth at the first location based on the sampled geomagnetic values; training a neural network-based azimuth estimation model based on the sampled geomagnetic values and the estimated azimuth; and estimating an azimuth at a second location using the trained azimuth estimation model.",
