Ocean Bottom Tiltmeters for Geophysical Research
The Carnegie Institution of Washington has installed two Jewell Instruments Model 510 Geodetic Borehole Tiltmeters in the sea floor east of Japan. The scientists are attempting to establish long-term sea floor observatories in one of the world's most active earthquake zones. Each observatory

INFLUENCE OF VIBRATIONS ON THE STABILITY OF GEODETIC SIGNALS AND INSTRUMENTS
Within the framework of present publications propagation and transference of vibrations by the ground from their source to geodetic instruments and marks were analysed and considered.

Global Geodetic Observing System
Unlike the ICRS, the realization of the ITRS through the ITRF is based on a combination of results from several space geodetic techniques, and local sur- vey measurements between reference points of geodetic instruments (so-called local ties) co-located at the…
