The SIMBIO-SYS (Spectrometer and Imaging for MPO BepiColombo Integrated Observatory SYStem) is a complex instrument suite part of the scientific payload of the Mercury Planetary Orbiter for the BepiColombo mission, the last of the cornerstone missions of the European Space Agency (ESA) Horizon + science program. The SIMBIO-SYS instrument will provide all the science imaging capability of the BepiColombo MPO spacecraft. It consists of three channels: the STereo imaging Channel (STC), with a broad spectral band in the 400-950 nm range and medium spatial resolution (at best 58 m/px), that will provide Digital Terrain Model of the entire surface of the planet with an accuracy better than 80 m; the High Resolution Imaging Channel (HRIC), with broad spectral bands in the 400-900 nm range and high spatial resolution (at best 6 m/px), that will provide high-resolution images of about 20% of the surface, and the Visible and near-Infrared Hyperspectral Imaging channel (VIHI), with high spectral resolution (6 nm at finest) in the 400-2000 nm range and spatial resolution reaching 120 m/px, it will provide global coverage at 480 m/px with the spectral information, assuming the first orbit around Mercury with periherm at 480 km from the surface. SIMBIO-SYS will provide high-resolution images, the Digital Terrain Model of the entire surface, and the surface composition using a wide spectral range, as for instance detecting sulphides or material derived by sulphur and carbon oxidation, at resolutions and coverage higher than the MESSENGER mission with a full co-alignment of the three channels. All the data that will be acquired will allow to cover a wide range of scientific objectives, from the surface processes and cartography up to the internal structure, contributing to the libration experiment, and the surface-exosphere interaction. The global 3D and spectral mapping will allow to study the morphology and the composition of any surface feature. In this work, we describe the on-ground calibrations and the results obtained, providing an important overview of the instrument performances. The calibrations have been performed at channel and at system levels, utilizing specific setup in most of the cases realized for SIMBIO-SYS. In the case of the stereo camera (STC), it has been necessary to have a validation of the new stereo concept adopted, based on the push-frame. This work describes also the results of the Near-Earth Commissioning Phase performed few weeks after the Launch (20 October 2018). According to the calibration results and the first commissioning the three channels are working very well.

SIMBIO-SYS：用于 BepiColombo 任务的科学相机和光谱仪

SIMBIO-SYS（MPO BepiColombo 综合天文台系统的光谱仪和成像系统）是水星行星轨道器科学有效载荷的复杂仪器套件，用于 BepiColombo 任务，这是欧洲航天局 (ESA) Horizo​​n 的最后一项基石任务+ 科学计划。SIMBIO-SYS 仪器将提供 BepiColombo MPO 航天器的所有科学成像能力。它由三个通道组成：STereo 成像通道 (STC)，具有 400-950 nm 范围内的宽光谱带和中等空间分辨率（最好为 58 m/px），它将提供整个表面的数字地形模型精度优于 80 m 的行星；高分辨率成像通道 (HRIC)，具有 400-900 nm 范围内的宽光谱带和高空间分辨率（最高 6 m/px），这将提供约 20% 表面的高分辨率图像，以及可见光和近红外高光谱成像通道 (VIHI)，在 400-2000 nm 范围内具有高光谱分辨率（最精细 6 nm），空间分辨率达到120 m/px，它将以 480 m/px 的光谱信息提供全球覆盖，假设第一个环绕水星的轨道距离表面 480 公里。SIMBIO-SYS 将提供高分辨率图像、整个表面的数字地形模型以及使用宽光谱范围的表面成分，例如检测硫化物或由硫和碳氧化衍生的材料，分辨率和覆盖范围高于信使任务与三个通道的完全一致。将获得的所有数据将涵盖广泛的科学目标，从表面过程和制图到内部结构，有助于振动实验和表面-外逸层相互作用。全局 3D 和光谱映射将允许研究任何表面特征的形态和组成。在这项工作中，我们描述了地面校准和获得的结果，提供了仪器性能的重要概述。校准已在通道和系统级别执行，在大多数情况下为 SIMBIO-SYS 实现了特定设置。在立体相机 (STC) 的情况下，有必要对采用的基于推帧的新立体概念进行验证。这项工作还描述了在发射后几周（2018 年 10 月 20 日）进行的近地调试阶段的结果。
