Nano Star Tracker AZDK-1 is designed first of all for nano and micro satellites, but can also be used on larger spacecrafts. Its dimensions, which are 56×60×93 mm, its weight is 193 g, and its average power consumption of 0.3W (1,25 W peak) enable to use it in a CubeSat satellites. AZDK-1 has a high attitude accuracy, which is achieved through a more complicated image processing, allowing of taking into account the systematic errors. It is expected that the use of CMOS photo sensor with effective size of 512×512 pixels and with an update rate of 5 Hz gives the attitude error σXY5". Attitude accuracy improvement technique was taken from the processing of astronomical images. In the article present the results of functional, vibrodynamic, thermal vacuum tests.
