摘要:

AMICal卫星是一颗专用的2U立方体卫星,已经开发出来,目的是用一个专用成像仪监测极光发射。它旨在帮助重建地球极光区高达30 keV的低能电子通量。它包括一个完全在格勒诺布尔大学航天中心设计的成像仪。该成像器采用1.3 Mpixels稀疏RGB CMOS探测器和宽视场物镜(f=22.5 mm)。卫星平台由波兰Satrevolution公司建造。它于2020年9月3日从库鲁(法属圭亚那)搭乘Vega 16航班发射,并于2020年10月制作了第一张图像。本文的目的是描述有效载荷的设计,特别是光学和邻近电子学,描述有效载荷用于空间天气目的。对显示这种仪器与极光监测的相关性的第一图像进行初步分析。该分析允许从第一图像中的一个重建在曝光时间期间大气顶部的局部电子输入通量。

英文摘要:

AMICal sat, a dedicated 2U cubesat, has been developed, in order to monitor the auroral emissions, with a dedicated imager. It aims to help to reconstruct the low energy electrons fluxes up to 30 keV in Earth auroral regions. It includes an imager entirely designed in Grenoble University Space Center. The imager uses a 1.3 Mpixels sparse RGB CMOS detector and a wide field objective (f=22.5 mm). The satellite platform has been built by the polish company Satrevolution. Launched September, 3rd, 2020 from Kuru (French Guyana) on board the Vega flight 16, it produces its first images in October 2020. The aim of this paper is to describe the design of the payload especially the optics and the proximity electronics, to describe the use of the payload for space weather purpose. A preliminary analysis of a first image showing the relevance of such an instrument for auroral monitoring is performed. This analysis allowed to reconstruct from one of the first images the local electron input flux at the top of the atmosphere during the exposure time.
