Space engineering - Star sensor terminology and performance specification; English version EN 16603-60-20:2014
Raumfahrttechnik - Terminologie und Leistungsspezifikation für Sternensensoren; Englische Fassung EN 16603-60-20:2014
Overview
In recent years there have been rapid developments in star tracker technology, in particular with a great increase in sensor autonomy and capabilities. This standard is intended to support the variety of star sensors either available or under development. This standard defines the terminology and specification definitions for the performance of star trackers (in particular, autonomous star trackers). It focuses on the specific issues involved in the specification of performances of star trackers and is intended to be used as a structured set of systematic provisions. This standard is not intended to replace textbook material on star tracker technology. The readers and users of this standard are assumed to possess general knowledge of star tracker technology and its application to space missions. This document defines and normalizes terms used in star sensor performance specifications, as well as some performance assessment conditions: sensor components, sensor capabilities, sensor types, sensor reference frames, sensor metrics. This standard specifies star tracker performances as part of a space project. The standard covers all aspects of performances, including nomenclature, definitions, and performance metrics for the performance specification of star sensors. The standard focuses on performance specifications. Other specification types, for example mass and power, housekeeping data, TM/TC interface and data structures are outside the scope of this standard. When viewed from the perspective of a specific project context, the requirements defined in this standard should be tailored to match the genuine requirements of a particular profile and circumstances of a project. This standard may be tailored for the specific characteristics and constraints of a space project in conformance with ECSS-S-ST-00. This document (EN 16603-60-20:2014) has been prepared by Technical Committee CEN/CLC/TC 5 "Space", the secretariat of which is held by DIN. This document has been developed to specifically cover space systems and therefore has precedence over any European Standard since it covers the same scope but with a wider domain of applicability (for example aerospace).
