Attitudes of the Antarctic Sounding Rocket Vehicles
The attitudes of the 12 sounding rockets which were launched at Syowa Station in Antarctica from May 1972 to August 1973 were determined by geomagnetic aspect sensors. The attitudes of the latest launched sounding rockets, S-210JA-22 and S-310JA-1 were also determinated. The three-dimensional orient...

| Summary: | The attitudes of the 12 sounding rockets which were launched at Syowa Station in Antarctica from May 1972 to August 1973 were determined by geomagnetic aspect sensors. The attitudes of the latest launched sounding rockets, S-210JA-22 and S-310JA-1 were also determinated. The three-dimensional orientation of the S-210JA-22 rocket axis was obtained by the geomagnetic aspect sensors and the solar aspect sensor. The result shows that the precessional motion of the S-210JA-22 vehicle included the geomagnetic field line. The spin frequency of these 14 vehicles was mostly in the range from 1.1 to 1.3Hz and their conical (precessional) half angle was mostly from 20 to 60 degrees, with the conical rotational period mostly from 50 to 120 seconds. |
