TS EN 16603-60-20

TS EN 16603-60-20 is a space engineering standard that addresses the terminology, definitions and performance specification framework for star sensors used in space projects. Star sensors are optical attitude sensors that determine spacecraft orientation from star imagery, so the subject of this standard is not only what the device is called, but also how its performance is defined and stated.

What the performance specification focuses on

The standard covers star sensor performance in a broad sense, with emphasis on nomenclature, definitions and performance requirements. In technical context, it gives particular attention to environmental influences such as temperature, radiation and stray light, because these can affect image quality, star identification and the stability of attitude determination. It also addresses robustness, meaning the ability to keep the sensor functional under non-nominal environmental conditions.

Boundaries of the document and interface context

Other specification types are explicitly outside the scope, including mass and power, housekeeping data and data structures. The standard also proposes a common core of functional interfaces defined by unit suppliers and avionics primes in the context of the SAVOIR initiative. In a project setting, the requirements are intended to be tailored to the genuine needs and constraints of a specific mission profile, making the document a common reference for describing star sensor performance rather than a one-size-fits-all system specification.
