Authors: EChO Team
This document aims at providing the description of the EChO reference payload complement. The payload complement comprises the following elements:
- The telescope
- The common optics, common in the sense that all alternative instrument designs must use this same set of fore-optics
- The instruments:
- The science instrument, defined as a spectrometer covering the complete wavelength range required in [EChO MRD (Mission Requirements Document), SRE-PA/2011.038/]. This wavelength range is split into different science channels.
- The Fine Guidance Sensor (FGS, acting as a non-scientific instrument), also required in [EChO MRD (Mission Requirements Document), SRE-PA/2011.038/] to answer the pointing needs of the spacecraft.
