The KSST01 Star Tracker is intended for use as a primary orientation determination device on micro and nano satellites, including CubeSat class satellites, as well as an additional or backup orientation determination device for larger classes.

​

The device determines its orientation in the inertial celestial coordinate system by observing stars in the visible wavelength range. The star sensor receives an image of a fragment of the starry sky using the built-in lens sensor on the built-in matrix receiver. In the resulting frame, images of stars are highlighted, for which coordinates are determined on a matrix radiation detector. The configuration of the stars in the frame is cored with the catalogue of navigation stars stored in the permanent memory of KSST-01, for which coordinates in the celestial coordinate system are known. The result of the corrosion is the identification of stars from the catalogue with images of stars in the frame. Using the identified stars, the orientation (reversal) of the sensor is calculated relative to the inertial coordinate system (ICS) associated with fixed stars. The procedure for determining the orientation is periodically repeated. The maximum repetition rate of the orientation determination procedure is 10 Hz.
