- Abstract
First durable orbital station (DOS) SALUT was launched in April, 1971. November 20, 1998 Russia launched Functional Cargo Block – First module of ISS. In Control System (CS) of MIR new approach was a contemporary ideology of CS design. Instead of analog devices in guidance and navigation CS and onboard complex CS the new onboard digital computing complexes were used. The first time in history MIR station CS were designed as open systems, which were able to extend their capabilities while station was growing. The new version of software was developed and installed in onboard computers using permanent memory units, in order to integrate new module to DOS. ISS is a unique experience of creation of a large orbital objects using international cooperation during all stages of design, development, ground verification and orbital flight of DOS. Integration of different modules and control over the whole Station is resolved by onboard control complex (OCC), which main parts are OCC’s of RS and USOS of ISS. OCC of ISS RS is build as more centralized system – OCC was initially designed to integrate Onboard Computer System, Guidance and Navigation Control System (GNC), Onboard Equipment Control System, Commanding Radio Link, Radio-Telemetry System. It is necessary to note that it was first time in a history of DOS, when integrated OCS was created including computer systems of Russian and American Segments of ISS. Integrated Command and Data Handling System (CDH) of RS and USOS allowed us to resolve the following important tasks: 1. Coordinated control over the whole ISS using ISS Modes concept. 2. Integration at the level of BS of the Station. Most complete integration was achieved in Guidance and Navigation System, which consists of RS GNC and USOS GNC. These two systems implement common motion control modes around center of mass and mass center motion. 3. Monitoring and control of the Station by ISS crew. Using CDH, crew has a capability to control all onboard systems and can monitor their behavior. 4. Robust control of ISS from MCC in Moscow and in Houston. If communication is lost between MCC and ISS, we can use radio links of other segment (RS or USOS) for command and control. 5. Uploading of new version of OCC software to accommodate ISS growth.
