Summary of the main error sources of the MEMS gravimeter

Error sources Characteristic Correction
Linear creep of structure Elastic relaxation. (DC~) Linear trend removal from the data.
Noise from electronics Noise from LED, QPD and other electronics. (DC~) Averaging and filtering.
Temperature change Temperature-dependent properties, such as Young’s modulus and sensitivity of optical devices. (DC~) Temperature control and temperature effect correction.
Seismic noise Man-made and natural sources. (>0.1 Hz) Averaging and filtering.
Wind-induced vibration Unexpected airflow. (>0.5 Hz) Windshield, averaging, and filtering.
Atmospheric pressure change Change of air buoyancy. Vacuum sealed.
