Abstract

Universal modular onboard control system OBCARM G2 NANO has been developed for 3U-12U nano-class spacecraft designed for communications, Earth remote sensing, or the Internet of Things. OBCARM G2 NANO consists of interface and processor modules on separate printed circuit boards. The Zynq Ultra scale+ SoC-based processor mod-ule provides ARM TMS470-based module telemetry control support and necessary peripherals, including 500 MB DDR4 RAM for the CPU, 125 MB RAM for the programmable logic gate array field-programmable gate array 125 MB QSPI Flash for flight software storing, and 128 GB eMMC Flash as ROM. Interface module contains onboard control system modules power lines, interfaces of the control system and payload data transmitter and receiver, as well as drivers that provide con-version and buffering of payload data. The OBCARM G2 NANO uses QNX RTOS for flight software, and a high-performance AXI bus for interaction between the processor system and field-programmable gate array. CAN bus is used to ensure spacecraft subsystems operation in a single network. The dimensions of the OBCARM G2 NANO mechanical equipment, including a set of temperature monitoring sensors and a thermal bridge for removing excess heat from hot spots, are 95 mm x 95 mm x 35 mm.
