Gravity

  • Sensor type: Fused quartz using electrostatic nulling
  • Reading resolution: 1Micro Gal
  • Standard deviation: <5Micro Gal
  • Operating range: World wide (8,000mGal without resetting)
  • Residual Long-term drift (Static): Less than 0.02mGal/day
  • Tares: Typically less than 5Micro Gals for shocks up to 20G
  • Automated corrections: Tide, instrument tilt, temperature, noisy sample filter
  • Operating temperature: -40C to +45C
