PATUXENT RIVER NAS, Md., 31 May 2016. U.S. Navy military aviation experts needed a 6U VME synchro/resolver-to-digital measurement motherboard to track rotating electronics subsystems. They found their solution from North Atlantic Industries (NAI) in Bohemia, N.Y.
Officials of Naval Air Systems Command at Patuxent River Naval Air Station, Md., announced their intention Friday to award a sole-source contract to NAI for the company's 64SD1 VME-6U synchro/resolver-to-digital measurement motherboard.
Resolvers and synchros are transducers that convert the angular position and velocity of a rotating shaft to an electrical signal. A resolver-to-digital or synchro-to-digital converter converts these signals to a digital output corresponding to the shaft angle and velocity. The specific application for the NAI 64SD1 was not specified in the Navy announcement. In July 2013, however, Naval Air Systems Command announced their intention to buy the NAI 64SD1 for the AN/UPX-29(V) Interrogator System Mode 5 shipboard identification-friend-or-foe (IFF) system aboard Navy Arleigh Burke-class guided missile destroyers.
The AN/UPX-24(V) interrogator set is manufactured by Northrop Grumman Corp. and integrates the NAI 64SD1. The AN/UPX-24(V) 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.
