Jewell Instruments, LLC
High Precision Tiltmeter for Geophysical Activity Jewell Instruments is proud to present the A601-2 tiltmeter series as the latest installment to its electrolytic sensor family for geophysical and geotechnical applications. This new model replaces the 520M geodetic platform tiltmeter as a more cost effective option, but without sacrificing much precision. The dual-axis sensor has the advantage of built-in micrometer leveling legs for easy installation on any horizontal surface. With an absolute gravity referenced...

To level the X- and Y-axes of the Model 520-W Geodetic Platform Tiltmeter, the user turns a knob that raises or lowers an invar screw by means of a worm gear assembly. One complete 360° turn of the knob turns the screw by 6°, or 1/60 of a revolution. The ½-inch diameter screw has a pitch of 40...
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...
...in its development, this technology may one day enable water treatment plants to purify water with ceramic membrane filters instead of harsh chemicals. , both assistant professors of civil and environmental engineering and geodetic science, and doctoral students Dong Chen and Mikko Lamminen described their...
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.

However, other sources that produce deformation of the Earth’s surface do not gener- ate seismic waves but are instead observable with sensi- tive geodetic instruments that measure the crustal deformation directly.
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 …
