This is the precision required for our specific application of the spring meter, to validate the ocean tides models along the Atlantic coast. The determination of the instrumental phase lag is not satisfactory. A precision of only a few seconds has been achieved.

This instrument is equipped with a step motor mounted directly on the axis of the micrometer. It becomes possible to do very precise micrometric calibration to determine the ratio between the micrometer screw rotations and the signal output modulations. The gravimeter was installed on the calibration platform which induces well known sinusoidal inertial accelerations at different periods controlled by a quartz clock. In parallel with the signal produced by the gravimeter, we register a signal coming from a displacement sensor which records the motion of the platform. This sensor has a scale factor referenced to a LASER interferometer. For periods in the range of 200 to 300 seconds, the phase lag between the gravimeter and the displacement sensor is quasi stable around 15 sec. It corresponds to the transfer function of the RC filter implemented in the Maximum Voltage Retroaction electronics. So a correction could be applied to the amplitude of the gravimeter signals, for compensating the frequency dependant attenuation. This is a key point for achieving a precise calibration with the inertial platform method. We shall also correct the scale factor of the micrometric screw of the PET 1006 gravimeter. With this new results, it becomes possible by recording simultaneously the tidal signal with different gravimeters, to derive tidal factors for the Brussels station and thus to determine the scale factor of the T03 cryogenic gravimeter.","PeriodicalId":39875,"journal":{"name":"Journal of the Geodetic Society of Japan","volume":"47 1","pages":"64-69"},"PeriodicalIF":0.0,"publicationDate":"2001-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.11366/SOKUCHI1954.47.64","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64263214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There have been compared the results of contemporary time series of two different tidal gravimeters (LaCoste&Romberg ET18 and ASKANIA GS15 No. 222). Deviations of the amplitude factors at both stations were observed with a mean value in the order of 0.7 percent. Nowadays it became possible to perform such measurements with a more up-to-date equipment and to evaluate it with improved methods. So was installed a LaCoste&Romberg (Type G) gravimeter between 1997 and 1999 in turns at both the stations and the time series were analysed using the ETERNA 3.3 analysis program. Deviations of the tidal amplitudes are nearly of the same amount as in the 197811980 measurements but with an opposite sign. Therefore possible reasons are discussed with regard to the quality of the error estimations. Furthermore a lower noise level was observed in both periods at Insulaner station in the inner city of Berlin.","PeriodicalId":39875,"journal":{"name":"Journal of the Geodetic Society of Japan","volume":"47 1","pages":"148-154"},"PeriodicalIF":0.0,"publicationDate":"2001-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64260025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The amplitude of these tidal signals is up to 2.5 cm and most of them are explained by the ocean tide loading displacement model by Matsumoto et al. (2000, 2001). The loading tide signals affect the troposphere delay estimates by more than 1 cm in southwestern Japan if they are not corrected. These tidal signals in the displacement and troposphere estimates are effectively eliminated by applying the ocean tide loading correction with the model for most of the major tidal constituents. The comparison of residual tidal signals by applying the two ocean loading models shows reduction of the residual M2 tidal signals by applying the correction with the newer model. These results demonstrate the capability of a dense GPS network to detect un-modeled tidal signals.","PeriodicalId":39875,"journal":{"name":"Journal of the Geodetic Society of Japan","volume":"47 1","pages":"187-192"},"PeriodicalIF":0.0,"publicationDate":"2001-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64260226","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
