Solar sail is expected to be one of the effective propulsion systems for future deep space satellites. JAXA/JSPEC has an experiment plan of solar sail mission "Ikaros". In this experimental mission, the assessment and control of solar radiation pressure is one of the mission success criteria. This paper presents the preliminary results on the acceleration estimation for Ikaros. For the first step, we estimate radiation pressure acceleration at the same time as spacecraft state vector. Using successive 7 pass tracking data, estimation precision with a several percent of total acceleration can be achieved. In the next step, model parameters of radiation pressure are estimated using the results of the first step. We confirm that the precision of estimated parameters depends on the correlation of each parameter.
