MICROSATPRO
Space Qualified Processor Unit
Space Qualified Processor Unit (MICROSATPRO) is a high performance on-board computer (OBC) compatible with micro satellite platforms for advanced space missions.
MICROSATPRO is a control unit that is resistant to harsh space conditions, has a high fault tolerance, reliable and high processor power. LEO is targeted as the operational orbit and it is designed to stay in this orbit for at least five years.
MICROSATPRO has an operating system running on FPGA (soft processor based). It is supported by interfaces frequently used in micro satellite platforms (RS485, RS422, CAN, Spacewire, SPI, I2C, etc.). Thanks to its modular design, integration into the target platform can be provided.
Single Event Effects (SEE) protection is provided through the use of a Fault Tolerant (FT-LEON3) processor core, Triple Modular Redundancy (TMR) in FPGA, Error Detection and Correction (EDAC) in memory units, Watchdog on software and Latch-up Current Limiter (LCL) in power units.
