| Outline of Final Research Achievements |
An accelerometer has been developed using crystal oscillator and it has very high sensitivity and accuracy in principle. This means that we can observe vibration, inclination, and gravity using only one sensor. However, the output data of acceleration is contaminated by fluctuation of temperature. We developed an algorithm to correct the affect by temperature and applied it to gravity data which was obtained in a real field. The corrected data can be applicable for basic gravity survey and the results suggested that more accuracy can be realized through a DOCX (double oven crystal oscillator) type system.
