Pre-processed snapshot of US navaid data from the 2026-04-16 FAA NASR cycle. Data only - no query logic, no dependency on @squawk/navaids.

Documentation

Part of the @squawk aviation library suite. See all packages on npm.

Coverage

• All non-shutdown US navigational aids: VOR, VORTAC, VOR/DME, TACAN, DME, NDB, NDB/DME, fan markers, marine NDBs, and VOTs
• Frequencies (MHz for VOR-family, kHz for NDB-family) and TACAN channels
• Elevation, magnetic variation, and service volume classification
• ARTCC assignment (low and high altitude)
• Power output, NDB class, operating hours, and simultaneous voice capability
• DME/TACAN component position when different from the main navaid

Installation

npm install @squawk/navaid-data

Usage

import { usBundledNavaids } from '@squawk/navaid-data';

// Inspect metadata
console.log(usBundledNavaids.properties.nasrCycleDate); // "2026-01-22"
console.log(usBundledNavaids.properties.recordCount);

// Use with @squawk/navaids for zero-config navaid queries
import { createNavaidResolver } from '@squawk/navaids';

const resolver = createNavaidResolver({ data: usBundledNavaids.records });

Consumers who have their own data pipeline can use @squawk/navaids alone and pass any compatible Navaid array at initialization.

Data format

Each record is a full Navaid object from @squawk/types. Key fields:

Data source

All data is derived from the FAA National Airspace System Resource (NASR) 28-day subscription, which is public domain. Navaid data comes from NAV_BASE.csv. The build pipeline that produces this dataset lives in tools/build-navaid-data.
