Abstract

Sounding rockets are cost-effective and rapidly deployable tools for directly exploring the ionosphere and microgravity environments. These rockets achieve their target altitudes quickly and are equipped with various scientific instruments to collect real-time data. Perigee Aerospace plans its inaugural test launch in the first half of 2024, followed by a second performance test launch in January 2025. The second launch, scheduled off the coast of Jeju Island, aims to reach an altitude of approximately 150 km with a payload of 30 kg, conducting various experiments in the suborbital region. Particularly in mid-latitude regions, the ionosphere sporadically exhibits increased electron densities in the sporadic E layers and magnetic fluctuations caused by the equatorial electrojet. To measure these phenomena, the sounding rocket version of ionospheric anomaly monitoring by magnetometer and plasma-probe (IAMMAP), currently under development at the KAIST Satellite Research Center, will be onboard. This study focuses on enhancing our understanding of the mid-latitude ionosphere and designing observable missions for the forthcoming performance tests.

사운딩 로켓은 저렴한 비용과 빠른 개발 기간을 통해 전리권이나 무중력 환경을 직접 탐사하는 유용한 도구이다. 이러한 로켓은 목표 고도에 신속하게 도달하며, 다양한 과학적 장비를 탑재하여 데이터를 실시간으로 수집할 수 있다. 페리지에어로스페이스(주)는 2024년 상반기에 첫 시험 발사를 진행한 뒤, 2025년 1월경에는 2차 성능시험 사운딩 로켓을 발사할 예정이다. 이 로켓은 제주 해상에서 발사될 예정이며, 약 150 km의 목표 고도에 총 30 kg의 탑재체를 싣고, 준궤도 영역에서 다양한 실험을 수행할 것이다. 특히, 중위도 지역의 전리권에서는 간헐적으로 전자 밀도가 증가하는 스포라딕 E층과 적도 전기제트에 의한 자기장의 미세변화를 관측할 수 있을 것으로 예상된다. 이러한 관측을 위해 KAIST 인공위성연구소에서 개발 중인 탑재체 IAMMAP(ionospheric anomaly monitoring by magnetometer and plasma-probe)의 사운딩 로켓 버전이 발사체에 실릴 예정이다. 본 연구는 중위도 지역의 전리권에 대해서 이해하고, 2차 성능시험에서의 관측 가능한 임무 설계에 중점을 두고자 한다.
