SECTION 1

1. OVERVIEW

1.1 PURPOSE. This document provides performance specifications for modernizing the Navigational Aids (NAVAIDS) Family of Systems (FOS) including the AN/FRN-44 Very High Frequency Omni-Directional Range (VOR), AN/FRN-45 Tactical Air Navigation (TACAN), and AN/FRN-43 Very High Frequency Omni-Directional Range Tactical Air Navigation (VORTAC).

This effort involves a modernization that replaces existing obsolete NAVAIDS FOS components with modern Commercial-Off-The-Shelf (COTS) equipment, integrates them into the existing infrastructure, and enables Maintenance and Remote Status (MRS).

1.2 AFFECTED EQUIPMENT.

1.2.1 Fixed based TACAN, AN/FRN-45, TACAN Navigational Set

1.2.2 Fixed based TACAN Antenna, OE-537/FRN, AT-100, TACAN Antenna Group

1.2.4 Fixed based VORTAC, AN/FRN-43 (to include the AT-100 antenna), Co-Located VOR and TACAN Navigational Sets

1.2.5 Fixed based TACAN Tower, AN/GRA-49 as well as other types of towers

1.2.6 The VOR, TACAN and VORTAC buildings/shelters are real property and under the control of local, base civil engineers. This includes the VOR counterpoise which is typically a part of the roof structure.

1.3 GENERAL

1.3.1 The USAF desires to reduce the logistical footprint of all the NAVAIDS devices.

1.3.2 This program is part of an Air Force Smart Operations for the 21st Century (AFSO21) initiative.
