VIRTUAL TRANSPONDER WITH IN-BAND COMMAND TRANSMISSION Russian patent published in 2021 - IPC H04B7/185 H04B1/59 H04L29/06 

FIELD: satellite communication.

SUBSTANCE: invention relates to virtual transponders with in-band command transmission. Systems, methods and devices for implementing a virtual transponder with in-band command transmission are proposed. The method includes transmitting, by a control center (CC of a tenant) of rented useful load (RUL), encrypted commands of the tenant to a receiving antenna of the tenant, transmitting, by means of the receiving antenna of the tenant, encrypted commands of the tenant to an antenna of useful load on a vehicle. The method also includes transmitting, by means of the control center of the lessor spacecraft, encrypted commands of the lessor to a vehicle, changing useful load configuration on the vehicle in accordance with unencrypted commands of the lessor and/or unencrypted commands of the tenant. In addition, the method includes transmitting, by means of the antenna of useful load, useful load data to a receiving antenna of the lessor and/or receiving antenna of the tenant. Besides, the method includes transmitting encrypted telemetry of the lessor to the control center of the lessor spacecraft and transmitting encrypted telemetry of the tenant to the control center of the lessor spacecraft and transmitting, by means of the control center of the lessor spacecraft, encrypted telemetry of the tenant to the control center of the rented useful load.

EFFECT: improvement in the transponder structure, which provides for confidentiality during resource allocating on the useful load.
