| Popis: | A description is given of the control structure of scientific instruments and data transfer management system involved in the CORONAS-PHOTON satellite mission. The technical capabilities of all specialized instruments to provide the function of the scientific instruments and spacecract (SC) support systems are unified in a single structure. The correctness of the proposed and implemented structure has been verified by the operation of the CORONAS-PHOTON’s complex of scientific instruments. Control of the scientific instruments was maintained using one-time and program pulse commands (OTC and PPC), as well as command data files (CDF), which are transmitted via onboard control units. Up to 30 OTC and 52 kbit of CDF can be transmitted per one control session. The date is transmitted to data-acquisition ground stations (DAGS) at Scientific center for Earth orbital monitoring. Up to 1.3 Gbyte of data can be transmitted per day. Data encryption and reception by two DAGS simultaneously was used to reduce the quantity of transmission failures. The CORONAS-PHOTON SC has been performing scientific experiments from February to December 2009. Over this period, 297 control sessions and 1050 data acquisition sessions were performed; about 5 Mbit of uplink control data were transmitted on board SC, and 250 Gbyte of scientific data were received by DAGS. |
