ABSTRACT:
A low noise, extended dynamic range accelerometer useful for sensitive seismic observations. The accelerometer's extended range is obtained by utilizing a single opposing magnetic field to non-linearly oppose movement of a magnetic proof mass. The accelerometer may also utilize an external bias magnetic field located apart from the magnetic proof mass to provide a constant gravitational offset source.
