RAD750
RAD750 is the name of a family of radiation-resistant microprocessors (CPUs) and single-board computers based on them , manufactured by BAE Systems Electronic Solutions . As the successor to the RAD6000 , the RAD750 processor is suitable for use in environments with high radiation values, such as on board satellites and spacecraft . RAD750 was launched in 2001 and the first units were launched into space in 2005 . The RAD750 is based on the IBM PowerPC 750 . The packaging and logic functions of the CPU are fully compatible with the PowerPC- 7xx family.
Dates (historical)
The version of the CPU offered in 2002 had 10.4 million transistors , almost an order of magnitude more than its predecessor, the RAD6000 (1.1 million). It had a chip area of 130 mm 2 and a chip clock of 133 to 200 MHz. The computing power was 240–366 MIPS . The processor required 5 watts of electrical power.
In 2009, two variants of the RAD750 were offered that withstood an absorbed dose of 2,000 and 10,000 Gy (= 200,000 to 1,000,000 rd ). The CPUs worked in the temperature range from −55 to 125 ° C. The standard RAD750 single-board computer (CPU and mainboard) withstood a total of 1000 Gy of ionizing radiation, accepted a temperature of −55 to 70 ° C and required 10 W of power.
In 2002, a RAD750 system was priced at about $ 200,000 per board, comparable to the RAD6000. However, the customer's program requirements and the quantities purchased have a major impact on the final cost per unit.
commitment
There are several spacecraft with RAD750 computers in operation. The comet probe Deep Impact , which was launched in January 2005, was the first spacecraft with a RAD750 computer. Two RAD750 computers are used in the WorldView-1 satellite, which takes high-resolution images of the earth. This started on September 18, 2007. Worldview-1 is part of the NextView program of the National Geospatial Intelligence Agency .
