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).

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 bernie.cortez@navy.mil, or by fax at 301-995-0875. For questions or concerns phone Cortez at 301-995-1773.
