OBC is Dragonfly's onboard computer product for low Earth orbit microsatellites.
OBC is Dragonfly Aerospace's high-reliability onboard computer with integrated AOCS interface and controller for LEO microsatellites.[1]
Dragonfly presents the OBC as flight-proven, ITAR-free, and TRL 9.[1][2]
The module uses a EuroCard 3U form factor, operates from -10 C to +50 C, measures 160 x 117 x 30.5 mm, and has a mass of 0.35 kg.[1]
Its power interface is a single 24-32 V input with 5 W consumption and 12 V, 5 V, and 3.3 V output supplies.[1]
The software environment includes Linux 4.14 for Xiphos Q7S, CCSDS TCTM, CCSDS File Delivery Protocol, direct command terminal, Lua scripts with systemd scheduling, satellite controller applications, and FDIR.[1]
The main processor set includes a dual-core ARM-A9 at 766 MHz, dual 256 MB SDRAM, dual 32 GB SD card, dual 128 MB flash, robust boot, data scrubbing, health monitoring, watchdog, RAM ECC, and in-flight reprogrammability.[1]
Main interfaces are 2x CAN, 2x SpaceWire, 14x RS422, 2x RS485, and DCL.[1]
The magnetic interface controller uses a hard 166 MHz 32-bit ARM Cortex-M3 FPGA with 12k LEs, 64 KB SDRAM, 256 KB flash, 2x CAN, 2x RS485, 3x 5 V H-bridge magnetorquer drivers, and 5x 0-5 V 12-bit ADC magnetometer inputs.[1]
