The Superconducting Submillimeter-Wave Limb-Emission Sounder (SMILES) observes 03 and other minor chemical species in the stratosphere and mesosphere. Limb observation of SMILES is sensitive to the quality of the tangent altitude retrieval. To obtain better retrieval result, knowledge of initial tangent height and antenna pattern should be as precise and accurate as possible. It was concluded that initial tangent height is calculated by using ISS attitude and mirror pointing angle, and ISS position. Antenna pattern assuming 6 points moving average was applied to the retrieval and showed reasonable results.
