For low earth orbit missions, there is always a question how to choose among Rad-Hard, Rad-Tol & COTS components for satellite & launch vehicle avionics.
Its a trade-off between cost, lead time & reliability. Component manufacturer is best person to guide developer on radiation analysis. Here is how CAVU AEROSPACE supports client in development stage.
Data-input: Orbit, launch data, Satellite or Launch vehicle shielding
Our solutions Radiation Analysis, Total Ionizing Dose (TID), Displacement Damage Dose (DDD), and Single Event Effects (SEE), Cost-Weight- Worth analysis, Radiation test reports, Rad sensors in products, SEE mitigation techniques in design stage.
Case study: OBC- Polar
- 2mm thickness AL7075 enclosure box: 6 kRad OBC weight: 220 gr
- 3mm thickness AL7075 enclosure box: 9 kRad OBC weight: 270 gr
- 4mm thickness AL7075 enclosure box: 5 kRad OBC weight: 320 gr
We have several SEE mitigation techniques in our products (Shielding weight/reliability worth assessment, TMR, ECC, EDAC & components positioning) effectively improves subsystem radiation resilience & reliability or at least help project developers to make decision between COTS or Rad-Tol components.
