The meeting on ensuring high precision spacecraft orientation based on modern astromeasuring systems, which was organized by Dynamic Systems Control Department was held on October 22, 2015 at the Space Research Institute NANU-SSAU. It was attended by representatives of Ukraine's leading space organizations: Yuzhnoye State Design Office, Research and Production Enterprise SMC «HARTRON-UCOM LTD» as well as SRI NANU-SSAU employees.

Two reports containing new approaches (proposed in SRI NANU-SSAU) for processing star sensors readings were presented on the meeting:

1. V. Gubarev, S. Melnychuk «High-precision astromeasuring system for spacecraft orientation».
2. V. Volosov, V. Kuntsevych, V. Shevchenko «Spacecraft orientation determining by vector directions measurements on the stars in the field of the star sensor».

Chief Designer of «HARTRON-UCOM LTD» N. Efimenko and Head of the Sector of Yuzhnoye State Design Office V. Horoshilov made critical remarks on the speed and accuracy of the spacecrafts orientation determining by using proposed approaches as well as generally accepted coordinate systems accounting.

Deputy General Designer for Development and Operation of Spacecraft, Satellite Systems, Instrumentation and Information-Management Systems of Space and Ground Segments Alexander Makarov noted the critical importance for Ukraine of solving various tasks of remote sensing. Improving methods on ensuring high precision orientation and satellite images binding is a basis for it solving. A. Makarov noted the meeting of ever increasing requirements for spacecraft orientation accuracy possible only by using astrosensors. Therefore, research on the using of astrosensors to improving accuracy of the spacecrafts orientation is certainly relevant and these studies should continue.

Academician V. Kuntsevych expressed the general opinion of the participants that meeting was successful and productive, and such meeting should be performed more frequently for adjustment of setting goals and methods of their solution.
