任务简介

XPoSat（X射线偏振卫星）是印度首个专用偏振测量任务，旨在研究极端条件下明亮天文X射线源的各种动态。该航天器将在低地球轨道上携带两个科学有效载荷。主载荷POLIX（X射线偏振仪）将测量8-30 keV中等X射线能量范围内天文起源光子的偏振参数（偏振度和偏振角）。XSPECT（X射线光谱与定时）载荷将在0.8-15 keV能量范围内提供光谱信息。此外，PSLV第四级上的10个附加载荷将进行由ISRO协调的印度各机构的各项实验和测试，称为PSLV轨道实验模块-3（POEM-3）。

XPoSat (X-ray Polarimeter Satellite) is India’s first dedicated polarimetry mission to study various dynamics of bright astronomical X-ray sources in extreme conditions. The spacecraft will carry two scientific payloads in a low earth orbit. The primary payload POLIX (Polarimeter Instrument in X-rays) will measure the polarimetry parameters (degree and angle of polarization) in medium X-ray energy range of 8-30 keV photons of astronomical origin. The XSPECT (X-ray Spectroscopy and Timing) payload will give spectroscopic information in the energy range of 0.8-15 keV. In addition, 10 attached payloads on the PSLV 4th stage will perform various experiments and testing from Indian institutions coordinated by ISRO, known as PSLV Orbital Experimental Module-3 (POEM-3).
