Abstract
The temperature asymmetry on the geodetic satellite Ajisai caused by the infrared radiation of the Earth produces a force along the satellite spin axis direction. This thermal thrust gives rise to an along-track acceleration and produces secular perturbations in the orbit elements, but no long-periodic perturbations exist if the spin axis of Ajisai is aligned with the Earth's rotation axis. The semi-major axis of the Ajisai orbit decays 1.7 m per year due to the Earth-heating effect, which is 50% of the drag effects experienced during the periods of low solar activity. The secular perturbation in inclination of -19 milli arc seconds per year is found but there is no secular perturbation in the eccentricity vector when the order of eccentricity is ignored.
