Operations

Operational Requirements
manipulator monoblock, transceiver with antenna on a mechanical adapter (TM/TC unit), onboard computer OBC, cable set.

Operational Protocols
Study of characteristics of S band radio signal propagation from the ISS RS through the ISS-Moscow radio link depending on the ionosphere condition, light-shadow situation, ISS distance and attitude. Modification of the ground S band receiving channel and its introduction into hardware/software complex UniScan-36. Organization and conduct of test operations to receive data from the ISS RS in Moscow using the ground hardware/software complex UniScan-36 and onboard TM/TC unit (a transceiver with antenna on a mechanical adapter) of Rokviss hardware. Organization and holding sessions to downlink data with digital images of URAGAN experiment (in case of successful completion of test operations).
