Commercial pressures are shifting the focus towards using rugged commercial off-the-shelf (COTS) space qualified data acquisition systems instead of more traditional radiation hardened systems. However, while the cost savings of using space COTS is significant over radiation hardened systems, they may not be suitable meet mission criteria in higher radiation environments such as low earth orbit

Curtiss-Wright has developed a system from feedback in the industry that uses a radiation hardened chassis that utilizes COTS modules. In the event of a Single Event Latch-ups (SEL) on a module, the backplane resets the module. This operation ensures that the potential harmful effects of ionizing radiation are eliminated. The backplane has the ability to switch modules on and off as desired for optimized power budgeting and provides continuous health status information and a watchdog capability.

Smart Backplane Chassis

Smart Backplane Chassis

The Smart Backplane chassis has been designed specifically for space-related data acquisition, data processing and recording. More>

  • Backplane designed using Rad-hard components allowing re-use of COTS plug-in modules, minimizing cost
  •  Detects Single Event Latch-Up (SEL) and corrects for normal operation, ensuring reliability
  •  Minimizes power consumption through different mission stages
Data Acquisition Modules

Data Acquisition Modules

Curtiss-Wright data acquisition units (DAUs) utilize modules to create custom systems using COTS elements. Modules are added to a chassis in whatever combination is desired. More>

  • Can be used in any combination in any order
  • Easily modify or upgrade your system by replacing modules
  • Commercial off-the-shelf flexible design with over 100 plug-in modules
