Space data acquisition systems and onboard data handling
Space applications typically put considerable stresses on space data handling due to the harsh environmental conditions and in particular because of the effects of radiation. Mitigating against these effects can be expensive but increasing commercial pressures are putting focus on keeping costs to a minimum for space missions. At the same time, there are various installation challenges that demand flexible systems.
Curtiss-Wright has a well proven range of data acquisition, video and transmission products that create Space COTS, radiation tolerant COTS and radiation hardened systems. By combining COTS savings with innovative radiation tolerant strategies, systems can be built that meet the needs of the mission at a significantly lower cost (by up to 75%).
The use of Smart Backplane design allows you to meet your Mission Assurance requirements without the high NRE and costs associated with radiation hardened designs. Additionally, custom modules can help lower weight by removing the need for separate avionics boxes while the ability to turn modules on and off allows you to efficiently manage power budgets.
This approach is proven on multiple Space applications including EASA Vega-C, NASA Orion SLS & CRV, Boeing CST-100, SpaceX Falcon 9 and Dragon, ESA IXV, ULA Delta V and Rocketlab Electron.
