TREADS - Testbed for Responsive Experiments and Demonstrations in Space |
- Technology demonstration platform for electronics, software and hardware
- Many more details at: http://www.redefine.com/TREADS/
- Reusable 'spacecraft bus' design
- Demonstrates new technology in a real-world radiation environment
- Integrates with real-world hardware for 'in-the-field' experimentation and system performance characterization
- Yields a competitive-edge for all its payloads by increasing Technology Readiness Levels (TRLs) at an inexpensive 'firm-fixed' price
