Flight tests of a miniature “space navigator” began in Russia

Roskosmos announced the start of flight tests of the small-sized star sensor AZDK-1 for small spacecraft.

“Space Navigator” is included in the modern ultra-compact Earth remote sensing satellite “Orbikraft – Zorky” manufactured by the Russian private space company “Sputniks”. This satellite was launched into low-earth orbit on March 22, 2021 by the Soyuz-2.1a launch vehicle among 38 spacecraft.

AZDK-1 was created by the Azmerit company, which is part of the Russian Space Systems holding of the Roscosmos state corporation.

A star sensor is a device designed to determine the spatial orientation of structures on which it is installed, relative to the inertial equatorial stellar coordinate system by observing stars in the visible spectral range.

The small-sized star sensor AZDK-1 is autonomous, it independently calculates the orientation quaternion and transmits it to the on-board computer of the spacecraft.

Before being sent into space, the AZDK-1 thermovacuum and vibrodynamic tests were carried out on the RCS bench equipment. The star sensor was subjected to sinusoidal and random vibrations, peak shock accelerations up to 25g. The device was kept in a thermal vacuum chamber for three days with a cyclic temperature change from minus 27 ° С to plus 57 ° С. During the tests, he confirmed the strength characteristics, as well as the ability to maintain the accuracy of determining the coordinates under load conditions during the launch of the vehicle into orbit and the influence of the space environment. The sensor passed this test program without failures and functioned normally.
