gravity measurements
Astronomical-Geodetic Observatory in Józefosław - Opis:
- Comparison of gravimeters relative to absolute measurements is frequently used method for determination of gravimeters scale factor. This technique as completely non-invasive is especially important in periodic control of continuously recording gravimetres. We used 30 repeated parallel observation of LaCoste&Romberg spring gravimeter with FG5 ballistic gravimeter in Józefosław Observatory carried out in last 40 months. Long series of repeated measurements allow us for comprehensive study on utility of calibration with this procedure. Different computational approaches was performed. Temporary variation of LCR scale factor with accuracy assessment aer comsidered. Discussion concerning reliability of calibration dependent on measurements length was also given.
