FIELD: space.SUBSTANCE: invention relates to space radio channels of digital information transmission. Summary of disclosed radio system is in establishing of operational control information (OCI) Earth-SC radio transmission channel by introduction into onboard and ground-based software-hardware on radio system target information reception points of devices generating and transmitting OCI on Earth and receiving and extracting OCI on SC, which enables to minimize interaction with Mission Control Center and reduce time from reception of requests on Earth remote probing (ERP) from consumers and formation of probing program until to obtaining of its implementation results on SC, during current communication session adapt into introduced on SC adjustable coding and modulation units of information signal-code structure to its conditions, selectively request from entire volume of information most data intensive probing data (PD) using introduced on SC PD analysis devices and PD directory, and into ground equipment is on-board information stream structure recovery devices. Radio system also includes errors and iterative queries detection device, improving data reliability by iterative query of erroneous information via “Earth-SC” channel. At that, onboard and ground equipment comprises multi-frequency transmitting and receiving devices, multi-wave antenna irradiators with common reflector and high-frequency filters units to maximize data transfer speed by means of their simultaneous transmission in multiple frequency bands. Besides, radio system comprises auto-tracking equipment on SC, simplifying requirements for SC in part of program-time tracking of onboard antennae in communication session with Earth.EFFECT: achieved technical result is increased volume of PD transmitted in session, increased ERP planning and performing processes, optimized PD release, as well as increasing radio system operation self-sufficiency, which increases ERP system efficiency in general.1 cl, 3 dwg |
