Actel FPGAs used in the NEAR Shoemaker spacecraft landing

25 April 2001 News

Actel played a significant role in the recent Near Earth Asteroid Rendezvous (NEAR) Shoemaker mission on 12 February, providing programmable logic that enabled mission managers to navigate the spacecraft to the surface of asteroid Eros and collect scientific data from the asteroid surface and surrounding environment. Actel says that its high-reliability field programmable gate arrays (FPGAs) were a part of the NEAR Shoemaker spacecraft, and played an important role in the command, telemetry and scientific data collection aspects of the mission. The successful touchdown of the spacecraft on asteroid Eros, even though it was not designed as a lander, makes the contributions of Actel's FPGA devices more significant, it said.

"Actel continues to be a key player in the technology behind major breakthroughs occurring in space and we plan to continue to push forward with our involvement in and development of high-reliability programmable logic technology," said Sunil Baliga, Vice President, Product Marketing at Actel. "Actel was proud to participate in the success of the Mars Pathfinder Mission of 1997 and we are again thrilled to play an integral part in another historic spacecraft landing, the NEAR Shoemaker."

Actel's radiation-tolerant RTSX-S devices were specifically developed for space applications. These devices include critical benefits such as immunity to single event upset (SEU) well above 37 MeV-cm2/mg, immunity to single event latchup (SEL), and performance capability of up to 100 Krads total ionising dose (TID). The RTSX-S devices also provide increased speed performance, mixed voltage support and the flexibility and effectiveness required by applications in harsh operating environments, according to the manufacturer.
