The attitude of two sounding rockets, S-310JA-11 and -12 launched at Syowa Station on May 29 and July 12,1985,were determined using magnetometers and horizon aspect sensors. The spin rate of the S-310JA-11 rocket was 0.57rps and the coning half angle of the precession was 8.8° with the period of 308s. The spin rate of the S-310JA-12 rocket was 0.59rps and the coning half angle of the precession was 25.0° with the period of 292s.
