JAXA 的全球变化气候观测任务 (GCOM-C) 航天器名为“SHIKISAI”，在日语中意为“色彩缤纷”，于 2017 年 12 月 23 日由 H-IIA 运载火箭 37 号航班 (F37) 成功发射。 GCOM-C是太阳同步极轨卫星，具有宽视场（FOV）和19通道光学成像仪，第二代全球成像仪（SGLI）。经过一天的关键阶段运行后，建立用于内务管理的卫星基本功能的重要卫星运行已成功完成。在校准和验证阶段之前，卫星总线和传感器已进行了为期三个月的初步调试活动，以确保传感器观测产品的准确性。本文介绍了我们在在轨运行的头几个月期间对 SGLI 进行的调试，以确认系统的完整性。重点阐述了月球定标和热红外性能的技术问题。
JAXA's Global Change Observation Mission for Climate (GCOM-C) spacecraft called "SHIKISAI", which means colorfulness in Japanese, was successfully launched on December 23, 2017 by H-IIA launch vehicle, Flight 37 (F37). GCOM-C is sun-synchronous polar orbit satellite with wide field of view (FOV) and 19 channels optical imager, Second Generation Global Imager (SGLI). The essential satellite operation to establish the satellite basic function to be used for the house keeping was successfully completed after the one day critical phase operation. The three months initial commissioning activities for the both satellite bus and sensor has been conducted before the calibration and verification phase to ensure the sensor observation product accuracy. This paper describes the commissioning of SGLI that we have performed during the first several months of in-orbit operation to confirm the system integrity. The technical aspects to the lunar calibration and the thermal infrared performance are specially described.
