AI 中文摘要
本文报告了小紫外相机（LUVCam1）首次在轨技术演示的状态。LUVCam1是2024年7月发射的2U立方星GRBBeta上的一个0.4U有效载荷。该任务的主要目标是对GSENSE4040 CMOS传感器及其读出电子学进行鉴定，为快速紫外千新星巡天者（QUVIK；Werner等人，引用\cite{Werner22, Werner24}）卫星做准备。LUVCam将作为该任务的主要科学相机。我们报告了LUVCam1上使用的GSENSE4040FSI传感器的性能，首先介绍其实验室表征，然后利用LUVCam1进行的天文观测评估其在轨性能。该相机两年后仍可运行，并拍摄了月球和恒星的图像，我们在此展示。通过LUVCam1，我们展示了一种利用新航天（new-space）方法鉴定最新商用现货（COTS）CMOS传感器用于天文任务的方法。
英文摘要
Here we report on the status of the first on-orbit technology demonstration of the Little UV Camera (LUVCam1). LUVCam1 is a 0.4U payload aboard the 2U cubesat GRBBeta that was launched in July 2024. The primary objective of the mission was to qualify the GSENSE4040 CMOS sensor and its readout electronics in preparation for the Quick UltraVIolet Kilonova Surveyor (QUVIK; Werner et al. \cite{Werner22, Werner24}) satellite. LUVCam will serve as the primary scientific camera for this mission. We report on the performance of the GSENSE4040FSI sensor used on LUVCam1, beginning with its in-lab characterization followed by an assessment of its on-orbit performance using astronomical observations made by LUVCam1. The camera remains operational two years later and has taken pictures of the Moon and stars that we show here. Through LUVCam1, we demonstrated an approach leveraging new-space to qualify the latest COTS CMOS sensors for astronomy missions.
