The satellite carries four main instruments, including the Spectroscopy Focusing Array (SFA), the Large Area Detector (LAD), the Polarimetry Focusing array (PFA) and the Wide Field Monitor (WFM), enabling simultaneous spectral-timing-polarimetry studies of celestial sources in the energy range from 0.5-30 keV. The satellite will fly at a near-zero-inclination Low Earth Orbit, and is featured with long-time steady high-precision coaxial pointing, near realtime burst alert distribution, and follow-up maneuver capabilities. This paper describes the primary mission requirements and constraints, and presents an overall mission analysis including orbit analysis, pointing strategy, and board-ground communications, etc. The preliminary design of eXTP satellite is also introduced, including satellite overall configuration, observation modes, avionics architecture and development plan. | Descripción: | Event: Space Telescopes and Instrumentation 2020: Ultraviolet to Gamma Ray, 114442E (13 December 2020). | Versión del editor: | https://doi.org/10.1117/12.2562138 | URI: | http://hdl.handle.net/10261/237570 | DOI: | 10.1117/12.2562138 | E-ISSN: | 1996-756X |
