  • 대기환경에 대한 오존의 영향이 증대되면서 오존에 대한 관심이 증대되었다. 이에 따라 대기중 오존 농도를 정확히 측정할 수 있는 오존 측정기에 대한 관심도 고조되고 있는 실정이다. 오존을 측정하기 위한 방법은 분석하는 방법에 따라 Ion Chromatography, UV/Vis Spectrometer, Spectrofluorimeter, Spectrometer(reflection)방법 등을 들 수 있으며(Zhou and Smith, 1997, Geyh etal. 1997), 이들 중 Spectrometer(reflection)를 이용하는 방법이 비교적 간단하다. 이 방법은 대기 중 오존과 반응하여 색도가 변화하는 착색제를 사용하여 색도 변화를 관측하여 오존 농도를 평가하는 방법이다.

  • This paper describes the development of an ozone detector and an electron probe as parts of scientific payloads for sounding rockets such as the KSR-III. Each detector consists of sensor parts and electronic parts. We successfully carried out the calibration tests with developed ozone detector and the space plasma simulation chamber tests with electron detector. These payloads could be onboard the KSR-III and with measured data, it is expected and temperature profile over the Korean Peninsular.

  • This paper describes the development of scientific payload system onboard the KSR-III. The ozone detector(UVR), Langmuir electron probe(LEP), airglow photometer(AGP), and magnetometer(MAG) constitute this system. The purpose of the ozone detector is to measure the ozone density profile and the LEP measures the electron density and temperature in the ionosphere over the Korean Peninsula. The AGP detects airglow in the mesosphere over the Korean Peninsular. The MAG provides rocket attitude and the magnetic fluctuation information during the flight. With the developed payloads, the ground calibration tests and the environmental tests have been performed.

  • In this paper, we have obtained the acceleration coefficient of the IMU (Inertial Measurement Unit) to prove reliability by analyzing the characteristic of the MEMS IMU installed in guided weapon systems for overseas export and the operating environment of the guided weapon system. Additionally, based on designed life testing, we performed life tests on three the IMUs and demonstrated a target lifetime of 12 years.
