UNSPSC 25173119: Non-directional beacon and associated equipment

The NDB is basically a simple transmitter radiating an omnidirectional signal which is modulated at intervals with the identification code. The basic signal is known as a carrier and is radiated at the frequency specified for the particular aid. The identification code is a 400 or 1020 cycle note superimposed on the carrier. Some installations include voice modulation to provide landing information and some others, for remote monitoring purposes, have one or two pips between idents.

UNSPSC 25173119 Non-directional beacon and associated equipment is a Commodity code with no relevant recent state and local procurement activity. The recent opportunities block contains no solicitations for beacons, beacon equipment, or related apparatus. Instead, the available state and local records show procurement of wastewater inventory components (Tampa), concert hall lighting retrofits (Wichita), microbial source tracking laboratory services (Santa Monica), SCADA system upgrades (Gallup), water lab testing (Meriden), vocational education equipment (Texas), electrical components (Hillsborough County), generator installation (DART), predictive maintenance services (Hillsborough County), and various networking events and informational forums — none of which map to beacon procurement or the code's scope.

The code shows insufficient recent activity to characterize an active state and local market. Interested firms should monitor procurement portals in states and municipalities with transportation, aviation, maritime, or emergency-management functions where beacon signaling and associated navigational or safety equipment appear in future solicitations. Until beacon-specific opportunities emerge in the state and local record, this code warrants a watch posture rather than active pursuit.
