Information unit (BI)
Information unit (BI)
Information unit is needed in order to provide control of the scintific equipment complex onboard the “Lomonosov” satellite. It provides collection, storage and transmitting of the telemetric information to the Earth.
Why is it necessary?
Information block is developed in order to provide operation of the scientific equipment complex onboard the “Lomonosov” satellite and its operative and flexible control during the execution of the scientific program.љ The service systems of the basic satellite platform can’t fit the requirements of the unique scientific experiments – complicated scientific equipment, huge volume of scientific information storage, high-operative control of the equipment, therefore it was necessary to develop a special information unit.
