    High-performance Fiber Optic Gyroscope (FOG) north finders provide, precise, and autonomous true north determination for accurate azimuth measurement, with typical accuracies ranging from
    0.3 ∘ 0.3 raised to the composed with power
    0 . 3 ∘
    down to
    0.02 ∘ 0.02 raised to the composed with power
    0 . 0 2 ∘
    . Key manufacturers and suppliers include Ericco Inertial Technology , Micro-Magic Inc (memsmag.com), and Cielo Inertial Solutions , specializing in applications like mining, drilling, and defense.
    Top Manufacturers and Key Products
    • Ericco Inertial Technology (China): Offers high-precision FOG north seekers (e.g., ER-DBY-1) with accuracy up to
      0.02 ∘ sec ψ 0.02 raised to the composed with power secant psi
      0 . 0 2 ∘ s e c 𝜓
      , suitable for static applications.
    • Micro-Magic Inc (memsmag.com): Provides the NF2000 and NF3000 series FOG north finders designed for high-accuracy, high-stability, and demanding navigation/alignment tasks.
    • Cielo Inertial Solutions : Manufactures the Terra 1000 NF, a high-performance system using closed-loop FOG technology for rapid, accurate, and autonomous North Finding.
    Performance Characteristics
    • Accuracy: Ranging from
      0.5 ∘ sec ψ 0.5 raised to the composed with power secant psi
      0 . 5 ∘ s e c 𝜓
      (high-precision mining/drilling) to
      0.02 ∘ sec ψ 0.02 raised to the composed with power secant psi
      0 . 0 2 ∘ s e c 𝜓
      (military/specialized surveying).
    • Speed: Fast north-seeking capabilities, with some units finding north in under 3 minutes.
    • Technology: These devices utilize closed-loop fiber optic gyroscopes combined with accelerometers for robust performance in GPS-denied environments.
    • Applications: Ideal for north-finding in underground mining, missile launch positioning, vessel orientation, and antenna alignment.
    Manufacturers like Ericco often provide customizable solutions depending on specific accuracy and environmental needs.
