Navy needs synchro/resolver-to-digital measurement motherboard from North Atlantic

PATUXENT RIVER NAS, Md., 19 July 2013. U.S. Navy aviation experts are conducting an industry competition to purchase synchro/resolver-to-digital measurement motherboards made by North Atlantic Industries in Bohemia, N.Y., for the AN/UPX-29(V) Interrogator System Mode 5 shipboard identification-friend-or-foe (IFF) system aboard the guided missile destroyer USS Thomas Hudner (DDG 116).

Officials of the Naval Air Systems Command at Patuxent River Naval Air Station, Md., have issued a solicitation (N00421-13-T-0422) for the model VME 64SD1 6U VME synchro/resolver measurement board manufactured by North Atlantic Industries to support AN/UPX-24(V) processor integration aboard the destroyer.

The AN/UPX-24(V) interrogator set from Northrop Grumman Corp. is the core identification-friend-or-foe (IFF) processor of the AN/UPX-29(V) shipboard interrogator system. It identifies aircraft and surface vessels equipped with selective identification feature (SIF) modes 1, 2, 3A, and C, and provides secure identification of cooperative mode 4 targets.

The IFF data from one AN/UPX-24(V) can be synchronized with as many as four individual radars, and provides the operator with synthetic IFF symbology for target recognition and tracking. The system is installed in Ticonderoga-class cruisers, Arleigh Burke-class destroyers, Wasp-class amphibious assault ships, San Antonio-class amphibious transport docks, and Nimitz-class aircraft carriers.

The Navy needs the model VME 64SD1 6U VME synchro/resolver from North Atlantic because the board is part of the AN/UPX-29 interrogator system configuration and works with all the current version of the AN/UPX-29 software, officials say.

Navy officials say they will accept proposals only for the North Atlantic model VME 64SD1 synchro/resolver. The boards must be new, not remanufacured, and come with the manufacturer's warranty.

The 64SD1 is a 6U VME synchro/resolver measurement board that provides 16 S/D converter channels, with velocity outputs that can be used in single-speed or two-speed modes. It provides wrap-around self-test, optional programmable reference supply, and is available for military or commercial applications, North Atlantic officials say.

The North Atlantic 64SD1 legacy synchro/resolver board offers 16-bit resolution (optional 24 bits combined); ±1 arc-minute accuracy; continuous background built-in testing with reference and signal loss detection; self calibration; 50 Hz to 10 kHz operation; tracking rate to 150 RPS; 16-, 12-, 8-, 4-, and 2-channel versions; programmable two-speed ratios: 2 to 255; power-on self-test (POST); digital velocity outputs; optional programmable encoder (A & B) plus index outputs; optional equivalent Hall Effect (A, B, C) commutation outputs; optional on-board programmable reference supply; watchdog timer and soft reset; angle change alert; transformer isolation; synthetic reference; optional conduction cooling with wedgelocks; I/O via front panel, P2 or both; latch feature; no required adjustments or trimming; part number, S/N, Date Code, and revision in non-volatile memory; and VxWorks library and driver support.

North Atlantic officials caution that the 64SD1 is a legacy product, and support for it remains within existing available documentation and software support. For new installations North Atlantic experts recommend the company's 64C2 single-slot 6U VME multi-function I/O and communications board, or 64C3 next-generation single-slot, 6U VME low-power/high-performance multi-function I/O board.

Companies interested in bidding should respond no later than 22 July 2013 by email to the Navy's Bernie Cortez by email at [email protected], or by fax at 301-995-0875. For questions or concerns phone Cortez at 301-995-1773.
