The RAD6000 radiation-hardened single board computer, based on the IBM RISC Single Chip CPU, was manufactured by IBM Federal Systems. IBM Federal Systems was sold to Loral, and by way of acquisition, ended up with Lockheed Martin and is currently a part of BAE Systems. It is mainly known as the onboard computer of numerous NASA spacecraft.
- the Spirit and Opportunity Mars rovers
- the Mars Pathfinder lander
- the Deep Space 1 probe
- the Mars Polar Lander and Mars Climate Orbiter
- the Mars Odyssey orbiter
- the Spitzer Infrared Telescope Facility
- the MESSENGER probe to Mercury
- the STEREO Spacecraft
- the IMAGE/Explorer 78 MIDEX spacecraft
- the Genesis and Stardust sample return missions
- the Phoenix Mars Polar Lander
- the DAWN Mission to the asteroid belt using ion propulsion
- the Solar Dynamics Observatory, Launched Feb 11, 2010 (flying both RAD6000 and RAD750)
- the Burst Alert Telescope Image Processor on board the Swift Gamma-Ray Burst Mission
The computer has a maximum clock rate of 33 MHz and a processing speed of about 35 MIPS. In addition to the CPU itself, the RAD6000 has 128 MB of ECC RAM. A typical real-time operating system running on NASA's RAD6000 installations is VxWorks. The Flight boards in the above systems have switchable clock rates of 2.5, 5, 10, or 20 MHz.
Reported to have a unit cost somewhere between US$200,000 and US$300,000, RAD6000 computers were released for sale in the general commercial market in 1996.
