## Autonomous Astronomical Navigation and Orientation System for Multipurpose Spacecrafts

Transactions of IAA RAS, issue 44, 75–82 (2018)

Keywords: autonomous navigation, autonomous orientation, recognition of stars, astronomical distant measurements, electronic optical devices, onboard management systems, functional stability.

### Abstract

This article proposes theoretical bases and the results we received modeling an autonomous astronomical navigation and orientation system applicable for multipurpose spacecrafts (SC). The system is realized on the basis of two methods developed by the authors. One of them is a high-precision method based on virtual measurements of zenith distances of stars. The second one is a modified calculation method estimating approximate parameters of the orbit and orientation of the SCs without a priori information. Both methods are based on measurements of star coordinates and their magnitudes in optical electronic devices. The estimates obtained through the second method are meant to become the basic data for the first one. The proposed system improves functional stability, stealth and autonomy characteristics.
