We present the calibration of the Insight-Hard X-ray Modulation Telescope (Insight-HXMT) X-ray satellite, which can be used to perform timing and spectral studies of bright X-ray sources. Insight-HXMT carries three main payloads onboard: the High Energy X-ray telescope (HE), the Medium Energy X-ray telescope (ME) and the low Energy X-ray telescope (LE). In orbit, the radioactive sources, activated lines, the fluorescence lines and celestial sources are used to calibrate the energy scale and energy resolution of the payloads. The Crab nebular is adopted as the primary effective area calibrator and empirical functions are constructed to modify the simulated effective areas of the three payloads respectively. The systematic errors of HE, compared to the model of the Crab nebular, are less than 2% in 28–120 keV and 2%–10% above 120 keV. The systematic errors of ME are less than 1.5% in 10–35 keV. The systematic errors of LE are less than 1% in 1–7 keV except the Si K–edge (1.839 keV, up to 1.5%) and less than 2% in 7–10 keV.

我们介绍了Insight-Hard X射线调制望远镜（Insight-HXMT）X射线卫星的校准，该校准可用于执行明亮X射线源的定时和光谱研究。Insight-HXMT机载三个主要有效载荷：高能X射线望远镜（HE），中能X射线望远镜（ME）和低能X射线望远镜（LE）。在轨道上，使用放射源，激活线，荧光线和天体源来校准有效载荷的能量规模和能量分辨率。采用蟹状神经元作为主要有效面积校准器，并建立了经验函数来分别修改三个有效载荷的模拟有效面积。与蟹状脑模型相比，HE的系统误差在28–120 keV时小于2％，在120 keV以上时小于2％–10％。在10–35 keV中，ME的系统误差小于1.5％。LE的系统误差在1–7 keV中小于1％，除了Si K–edge（1.839 keV，高达1.5％），在7–10 keV中小于2％。
