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).
Increase of the channel data flow to downlink data to the ground through the transfer to a higher frequency range of transceivers (S band).
