SPACE PLATFORM SERVICE UNIT Russian patent published in 2024 - IPC B64G1/22 

FIELD: cosmonautics.

SUBSTANCE: invention relates to space engineering, specifically to space platforms of CubeSat format. Space platform service unit comprises housing, onboard control system, motion and navigation control system, power supply system and onboard radio system. Charger board consists of conversion channels, to which a set of solar panels is connected, and includes a temperature sensor, solar panels current and voltage sensors, a primary power supply bus voltage sensor and a service unit reset circuit based on an external signal. Heating element is installed on the battery board. Microcontroller contains a thermal sensor and two cores, wherein one is turned relative to other by 90 °C and inverted, and a delay is introduced into the signals of each core. Microcontroller memory sectors contain software copies. Transceiver module of the VHF communication line operates in half-duplex mode. Onboard radio system includes a drop-down quarter-wave monopole forming a uniform beam pattern in a solid angle of 360 °C.

EFFECT: increased reliability of space satellites of CubeSat format during their operation, reduced time of their manufacturing, testing and installation.
