The RAD750 is a radiation-hardened single board computer manufactured by BAE Systems Electronics, Intelligence & Support.[1] The successor of the RAD6000, the RAD750 is for use in high radiation environments experienced on board satellites and spacecraft.[2] The RAD750 was released in 2001, with the first units launched into space in 2005.[1][3]
The CPU has 10.4 million transistors, an order of magnitude more than the RAD6000 (which had 1.1 million).[3] It is manufactured using either 250 or 150 nm photolithography and has a die area of 130 mm2.[1] It has a core clock of 110 to 200 MHz and can process at 266 MIPS or more.[1] The CPU can include an extended L2 cache to improve performance.[3] The CPU itself can withstand 200,000 to 1,000,000 rads (2,000 to 10,000 gray), temperature ranges between –55 °C and 125 °C and requires 5 watts of power.[1][3] The standard RAD750 single-board system (CPU and motherboard) can withstand 100,000 rads (1,000 gray), temperature ranges between –55 °C and 70 °C and requires 10 watts of power.[3]
The RAD750 system has a price that is comparable to the RAD6000 which is US$200,000 per board (per 2002 reference).[4] However customer program requirements and quantities will greatly affect the final unit costs.
The RAD750 is based on the PowerPC 750.[1] Its packaging and logic functions are completely compatible with the PowerPC 7xx family.[3]
The term RAD750 is a registered trademark of BAE Systems Information and Electronic Systems Integration Inc.[5]
Deployment
In 2010, it was reported that there were over 150 RAD750s used in a variety of spacecraft.[6] Notable examples,[2] in order of launch date, include:
- Deep Impact comet chasing spacecraft, launched in January 2005 - first to use the RAD750 computer.[2]
- XSS 11, small experimental satellite, launched April 11, 2005[2]
- Mars Reconnaissance Orbiter, launched August 12, 2005[2]
- SECCHI (Sun Earth Connection Coronal and Heliospheric Investigation) instrument package[7] on each of the STEREO spacecraft, launched October 25, 2006
- WorldView-1 satellite, launched Sept 18, 2007 - has two RAD750s.[6]
- Fermi Gamma-ray Space Telescope, formerly GLAST, launched June 11, 2008
- Kepler space telescope, launched in March 2009[2]
- Lunar Reconnaissance Orbiter, launched on 18 June 2009
- Wide-field Infrared Survey Explorer (WISE) launched 14 December 2009[8]
- Solar Dynamics Observatory, launched Feb 11, 2010
- Juno spacecraft, launched August 5, 2011[9]
- Curiosity rover, launched November 26, 2011[10]
- Van Allen Probes, launched on August 30, 2012[11]
- InSight, launched on May 5, 2018[12]
- Mars 2020 rover, to be launched 17 July 2020.[13]
