During the IMS period (1976-1978), 19 sounding rockets were launched at Syowa Station, Antarctica. 12 rockets of these were S-210 type vehicles and 7 rockets were S-310 type vehicles. Vehicle attitudes have been determinated by use of geomagnetic aspect sensors and other aspect sensors. Most of the S-310 type vehicles took stable flight aspects with the average precession angle about 13 degrees and the period about 192s. In the characteristics of S-210 type vehicle attitudes three kinds were distinguished; the first had aspects of small precession angles and long periods, the second had aspects of large precession angles and short periods, and the third had aspects of intermediate precession angles and periods. The average precession angle of S-210 type vehicles was about 32 degrees and the period was about 72s.
