    MEMS vs FOG: What Inertial System Should You Choose?
    View all
    Fiber Optic Gyroscope (FOG)-based attitude determination systems are high-precision sensors used for orientation and navigation in aerospace, defense, and autonomous systems, particularly in GNSS-denied environments. These systems use the Sagnac effect to measure rotation with extreme accuracy. Major manufacturers include GuideNav , Safran , EMCORE Corporation , MostaTech , and Northrop Grumman , offering solutions with low bias instability, often below
    0.003 ∘ 0.003 raised to the composed with power
    0 . 0 0 3 ∘
    per hour.
    Key Aspects of FOG-Based Systems
    • Performance: FOG sensors offer superior accuracy and stability over MEMS, featuring no moving parts, which minimizes wear and tear.
    • Applications: They are utilized in UAVs, UUVs, autonomous vehicles, and satellite ADCS (Attitude Determination and Control Systems).
    • Manufacturing: Key manufacturers like Gem Elettronica focus on in-house production of fiber winding, electronics, and algorithms.
    • Miniaturization: Modern FOG-based IMUs (Inertial Measurement Units) are available in low-SWaP (Size, Weight, and Power) configurations, such as the MostaTech VG221LN-MS , which is suitable for compact applications.
    Prominent Manufacturers and Products
    • GuideNav: Provides FOGs with high bias stability (
      0.003 ∘ 0.003 raised to the composed with power
      0 . 0 0 3 ∘
      /hr).
    • Safran: Produces FOG & FMU series for AHRS (Attitude and Heading Reference Systems) and stabilization.
    • EMCORE: Offers the GEO-FOG 3D system, using the P-1750 FOG IMU.
    • MostaTech: Specializes in miniature, low-noise FOGs (e.g., VG221LN-MS).
    • Northrop Grumman: Produces the LN-200 FOG family.
    • Exail: Manufactures Phins, an INS for high-accuracy heading and attitude.
    • Micro-Magic : Offers high-precision M3G-2XX series gyroscopes.
