ISS Science for Everyone

Science Objectives for Everyone
The Telemetry Data-Based Determination of the Dynamic ISS Characteristics (Tenzor) investigation was carried out in order to test the methods for determining and updating the ISS dynamic characteristics based on the telemetry data reflecting the motion control system operation. The rationale for initiating Tenzor was the proposed changes in the ISS dynamic characteristics required because of the ISS reconfigurations for Progress or Soyuz vehicle docking/undocking operations, cargo transfer, operating fluids consumption, installation activities aboard the station, etc, which have an indirect impact on the interrelation of the ISS moments of inertia, aerodynamic characteristics, and center of mass position.

Results/More Information

The data obtained by Tenzor are used to increase the effectiveness of ISS flight control, since more accurate dynamic parameters entered into the mathematical simulations at the ground complex and into the station computer system increase the reliability and predictability of station behavior when maintaining a specified angular position or changing the ISS attitude.

Based on the data obtained by Tenzor a feasibility study was carried out on controlling the Yamal-200 spacecraft attitude based on the mathematical simulation of its motion. To increase the accuracy of this simulation and of the motion control system operation, the dynamic characteristics of the spacecraft were refined. The study results demonstrated the feasibility of controlling the Yamal-200 spacecraft using the mathematical simulation of angular motion.

Therefore, the results obtained for the ISS (method for updating the mass value based on the mass of the launched satellite) provide additional capabilities to perform flight control tasks, plan experiments, and analyze experiment results obtained.
