Abstract
Gravimeters are used for measuring the local gravitational acceleration. The use of current commercially available gravimeters, however, has been limited by their high cost and large size. In this study, a microelectromechanical system (MEMS) based relative gravimeter with an acceleration sensitivity of 8 μGall / √ (Hz) is demonstrated. The MEMS gravimeter, along with the custom interface electronics, is embedded on a battery powered portable platform. The portable platform enables continuous recording of the sensor response, while simultaneously measuring critical temperature and tilt parameters. To demonstrate the long-term stability of the system, the reported MEMS gravimeter platform was used to detect the Earth tides. In this paper, the first results from these measurements have been discussed.
