  • Superconducting Gravity Meter

    iOSG - GWR

    The iOSG™ Observatory Superconducting Gravity Meter is the latest, lowest-noise observatory-quality SG. It builds on the industry-leading OSG that has formed the core of the Global Geodynamics Project (GGP) network of observatory ravimeters.1,2. Supercurrents flowing in the coils produce a magnetic field which levitates the sphere. The levitating sphere and magnetic field replace the function of the mass and mechanical spring found in other relative gravity meters.

  • Gravity Sensors

    iGRAV - GWR

    Superconducting persistent currents (i) produce the most stable relative gravity meter in existence. Superconducting persistent currents (i) produce the most stable relative gravity meter in existence. Super stable: Drift less than 0.5 µGal/month Scale factor constant to better than 1 part in 104 for years! Super precise: 1 nanoGal (10-3 µGal) in frequency domain 0.05 µGal in the time domain for 1 minute averaging. Super low noise: 0.3 µGal/(Hz)½.
