We have successfully completed the full space qualification of our CORTEX avionics line. CORTEX avionics are built in slices, each slice is enclosed in a thin aluminum frame containing the Printed Circuit Assembly (PCA) card and a flex harness terminating to one or more external connectors. The PCAs conform to the CubeSat form factor and are available in a wide range of Models suitable for most any space application. The slices are modular to allow for the customer to mix and match certain cards to define a custom architecture. CORTEX avionics have a mission design life of 3 years at low Earth orbit.
The qualification program included
- Shock testing
- Random Vibration testing at 17.9 grms (non-operational), 4.27 grms (operational)
- SEE Radiation Testing up to 37 MeV
- TID Radiation analysis up to 15 krad
- Thermal Vacuum testing from -30 to +60 degrees C (operational), -40 to +70 degrees C (non-operational)
All CORTEX cards undergo board level test and check-out and all integrated flight units undergo acceptance testing including random vibration, thermal cycling and complete comprehensive functional testing prior to delivery to verify workmanship
CORTEX avionics are a robust, commercial-off-the-shelf (COTS) avionics solution for small satellites and spacecraft and are now available as space-qualified products in the Spaceflight Industries product line.
