JAXA Research and Development Report: Research Reports on High Altitude Balloons
The Polar Patrol Balloon (PPB: Polar Patrol Balloon) Project that was planned for the polar geophysical observations was carried out by the 44-th Japanese Antarctic Research Expedition at Syowa Base, Antarctica in January 2003. Fluxgate magnetometer system was loaded on 3 balloons and the geomagnetic field was measured. It is very difficult to detect vector perturbations of the geomagnetic field by balloon because the motion of the sensors during the flight is irregular and complex. A high resolution fluxgate magnetometer system has been developed that is composed with 8-directional sun pulse sensor, 2-axial clinometer and a pulse clock counter. Two PPBs were launched on 13th January 2003. Their flights were apart 150 km from each other and at an altitude of 31.5 km. It was possible to get 2 magnetometers data for 11 days and 25 days respectively. As a result, the attitude change of the gondola were detected but small perturbation of magnetic field vector was undetected because of balloons were not rotated due to spin motor trouble. Here described are the new magnetometer system and results of magnetometer data analysis.
