Cosmonauts onboard ISS are to try out the manual control system of Progress MS

June 24, 2016

In accordance with the International Space Station (ISS) mission plan, on July 1, 2016 a trial test will be run on Progress MS cargo spacecraft of the upgraded system for remote control of the spacecraft – TORU (teleoperator control mode). The trial is necessary in order to complete the program of flight tests of Progress MS cargo spacecraft.

In the course of the scheduled tests the cargo spacecraft will depart at 08:35 Moscow Time from the docking compartment Pirs (DC-1) of the ISS to the distance of about 200 meters for a comprehensive check of TORU operation. The control of the cargo spacecraft will be assumed by the Roscosmos cosmonauts currently staying onboard the ISS Alexei OVCHININ and Oleg SKRIPOCHKA.

The final stage in the testing will be to re-attach the Progress MS to the station. The docking in the manual control mode is scheduled for July 1, 2016 at 09:10 Moscow Time to the module DC-1 Pirs of the ISS.

The TORU system is a system for remote manual control of spacecraft motion, and provides control via two joysticks and a control panel onboard the ISS.One of the joysticks controls the spacecraft translation, the other controls its attitude.The system also includes a TV camera installed on the spacecraft that is being docked.

The new-series transportation spacecraft Progress MS and Soyuz MS were developed as a result of a radical upgrade of Progress M and Soyuz TMA spacecraft.

The onboard command radio system Kvant-B was replaced with an integrated command and telemetry system with an additional telemetry channel. The new command radio link will make it possible to receive signals via relay satellites Luch-5, which will significantly increase the radio coverage zone for the spacecraft – up to 70% of an orbit.

The new-model spacecraft are equipped with an advanced onboard radio system for rendezvous and docking Kurs-NA. As compared with an earlier model, Kurs-A, it has improved mass and dimensions parameters and makes it possible to delete from the spacecraft hardware configuration one of the three radio antennas.

Instead of the analog TV system Klyost, the spacecraft will use a digital TV system, which will make it possible to maintain communications between the spacecraft and the station via a space-to-space RF link.

Also included into the onboard equipment of the Soyuz MS and Progress MS series spacecraft to replace the equipment that is being phased out of production is a new Digital Backup Loop Control Unit developed by RSC Energia, an upgraded Rate Sensor Unit BDUS-3A and a LED headlight SFOK.

Thanks to the use of new ground and onboard radio systems, it became possible to use state-of-the-art data transmission protocols, which resulted in improved operational stability of spacecraft control system.

Most of the engineering solutions incorporated into the design of Soyuz MS and Progress MS spacecraft will be used in the design of the new-generation Crew Transportation Spacecraft, which is currently under development at RSC Energia.
