Design of an OD-19 to the URN-33 and adding back the antenna lanyard to the OE-4691 production.

The Naval Air Systems Command (NAVAIR) intends to award a sole source contract to Thales USA, Inc. to develop an integrated AN/URN-33 Printed Wiring Board (PWB) module. This module will include all hardware and software necessary to convert a ship heading input, formatted in the USN proprietary OD-19 message format, to the NMEA 0183 RS-422 format. The contract will also update the OE-4691 drawings to include the antenna radome lanyard and supporting hardware from the OE-273 design. Key aspects of this opportunity include: • Development of an integrated AN/URN-33 PWB module • Conversion of ship heading input from OD-19 to NMEA 0183 RS-422 format • Update of OE-4691 drawings to include antenna radome lanyard and supporting hardware • Thales USA, Inc. is the sole designer, developer, and manufacturer of TACAN, making them the only source with the requisite knowledge and expertise.
