FGPS MagVar Database 1.0

FGPS MagVar Database is a high-precision magnetic variation (declination) dataset and lookup engine designed for navigation, avionics, and geospatial applications. Developed by FGPS International, it delivers accurate, time-aware magnetic variation values worldwide to support true-to-magnetic and magnetic-to-true conversions in both real-time and offline environments.

Key features:

• Global, time-aware coverage: Provides declination values across the globe with model-epoch awareness for consistent results over time.
• Standards-aligned modeling: Compatible with industry-standard geomagnetic models and practices to support robust operational use.
• Fast, lightweight lookups: Optimized interpolation and compact data structures deliver deterministic performance on embedded devices and in the cloud.
• Flexible integration: Offers a clean, well-documented API with bindings for common programming languages, plus a command-line utility for batch processing.
• Multiple data formats: Distributes in compact binary for runtime efficiency and human-readable formats (such as CSV/JSON) for analysis and tooling.
• Offline-ready: Once deployed, no network connection is required for queries, making it suitable for field and onboard systems.
• Versioned updates: Regular, clearly versioned releases with checksums to simplify validation and change management.
• Cross-platform support: Works on Windows, Linux, and macOS, with builds for both x86 and ARM architectures.

Common use cases:

• Avionics and flight management: True-to-magnetic conversions for headings, course calculations, and procedure coding.
• GIS and surveying: Accurate declination values for map production, field data collection, and spatial analysis.
• Maritime, UAV, and autonomous systems: Reliable magnetic references for navigation and mission planning.

Notes:

• FGPS MagVar Database provides reference data and computation tools and is not a substitute for official aeronautical or hydrographic information. Always verify and comply with applicable regulatory requirements.
