RADAR PROCESSING: Navy chooses 6U VME single-board computers from Curtiss-Wright for shipboard radar

U.S. Navy radar experts needed 6U VME single-board computers based on Freescale MPC7447A/7448 processors with AltiVec technology for radar systems aboard the littoral combat ships USS Little Rock (LCS 9) and USS Sioux City (LCS 11). They found their solution from Curtiss-Wright Controls Defense Solutions in Ottawa.

Officials of the Naval Air Warfare Center Aircraft Division Lakehurst at Joint Base McGuire-Dix-Lakehurst, N.J., announced a plan to award a contract to Curtiss-Wright to provide 434 SVME-183 6U VME embedded computing boards for the AN/UPX 29A interrogator system and AN/UPX-24(V) interrogator sets on the Little Rock and Sioux City.

Navy experts also will use the Curtiss-Wright SVME-183 computer boards for the Navy's AN/TPS-59(V)3 tactical missile defense radar, which can detect and track aircraft and missiles at ranges as far as 300 nautical miles. The value of the Navy contract to Curtiss-Wright has yet to be negotiated.

The AN/TPS-59 from the Lockheed Martin Corp. Mission Systems and Training segment in Syracuse, N.Y., is a three-dimensional solid-state linear-phased array surveillance radar that operates in the D band (1215-1400 MHz), and has 54 transmitters that operate independently, and can also operate in the two-dimensional mode should its general-purpose computer fail.

The Curtiss-Wright VME-183 single-board computer uses the single/dual Power Architecture MPMC7447A/7448 microprocessor with AltiVec technology from Freescale Semiconductor in Austin, Texas. The board also has as much as two gigabytes of DDR SDRAM solid-state memory.

The board has two 64-bit PCI Mezzanine Card (PMC) sites, one supporting 100 MHz PCI-Express, and an I/O Ethernet, as many as six serial ports, as many as two MIL-STD-1553 channels, SCSI, SATA, and two USB 2.0 ports.

Curtiss-Wright engineers designed the VME-183 single-board computer for data and digital signal processing in tactical aircraft, armored vehicles, and harsh-environment naval systems such as the littoral combat ship.

Navy officials say they intend to award Curtiss-Wright a five-year firm fixed price indefinite delivery indefinite quantity contract for the computer boards, which have a unique feature called an interface personality module that enables users to route signals on the embedded computer to specific VME P-zero and P-two pins of their choosing.
