The ÅAC Microtec data handling system (DHS) units are designed to combine low cost with high reliability for small satellites, but can also be used in other embedded control applications.
They are split into the RIA and Sirius product families which both have a modular design made for easy integration into your system. All flight units manufactured to the highest industrial standards and are tested against environmental effects, such as vibration, total ionizing dose (TID) and single event effects (SEE).
Most units have flight heritage, feel free to ask us about more detailed information on the flight performance. While the RIA product family is made to be tightly integrated with your units, the Sirius product family has higher performance and is designed as free-standing modules.
ÅAC Sirius avionics products are tailored to meet increasingly demanding requirements on reliability, resilience and low power consumption. Their form factor, mass and dimensions make them attractive for the small satellite market and launch vehicle segments where a reduction in the size and mass of their power and data handling sub-systems are key factors. The capacity for onboard data handling, data storage and data transfer meets the current trend towards more advanced missions in smaller spacecraft.
Compared to ÅAC Microtec’s earlier product, OBClite, ÅAC Sirius avionics feature a bigger and faster FPGA, which comes with 50% free capacity for custom RTL to meet demands for functionality and communication interfaces that are not part of the standard offering. Communication interfaces like CAN, MIL1553 and time triggered ethernet (TTE) can, for example, be offered.
ÅAC Sirius avionics can be integrated with products from the ÅAC rapid integration architecture (RIA) product line through various communication interfaces such as I2C, RS232, RS422, RS485 and SpaceWire. A hybrid system design of ÅAC Sirius avionics and RIA products benefits from the increased processing power of the larger and faster FPGAs of the former systems, as well as the minimalistic form factors of the μRTU and nanoRTU of the latter.
