Abstract: In this paper, we present user-cases for Astrix NS. Astrix NS is a new commercially available space gyroscope. It is small and precise enough to enhance the telescope line-of-sight (LOS) command and control loop. Moreover, its fully solid-state technology (no moving or vibrating parts) avoids any parasitic vibrations that could damage the performances of the telescopes and prevent its installation close or even inside the optical instrument. With an absolute angular knowledge error (AKE [1]) of 0.3 μrad at 10 milliseconds inside a 100 x 100 x 100 mm box and 1.4 kg weight, Astrix NS can be placed inside or near the telescope. Then, it can measure the deformation of the satellite or telescope structure in order to compensate them and to enhance imaging performances. Astrix NS is designed and qualified for LEO and GEO missions. Its performances, such as an ARW of 5 m°/√h and down to 2.5 m°/√h, a scale factor life stability below 200 ppm and a bias stability of 0.02°/h, already allow Astrix NS to be used in a large range of classical AOCS roles: telecommunication, Earth observation and scientific missions.
