On the geodetic assumptions for the measurement of the neutrino velocity

Measurement, 2014
Abstract The geodetic assumptions for the measurement of the neutrino velocity by applying the standard time of the Global Positioning System (GPS) and the length of the basis, which is defined by the geodetic measurements, are presented. The experimental data were taken from the OPERA and ICARUS experiments where neutrino emission from CERN LHC ...

Measurement of Displacement and Deformation by Geodetic Methods

Journal of the Surveying and Mapping Division, 1961
Geodetic methods provide only means of determining absolute terrain displacements; aspects of triangulation, trilateration, and use of electronic distance measuring devices; new equipment and its operation is described.

Physical correlation of repeated geodetic measurements

Journal of Geodynamics, 1988
Abstract Zones of active orogeny with rapid and irregular movements (e.g. the Alphine-Himalaya belt) and a zone of slow movements (East-European and Siberian platforms) are differentiated. A coefficient of correlation between the standardized leveling circuit misclosures of two epochs, r = 0.5 , was positively obtained for the areas of slow ...

MEASUREMENT OF TEMPERATURE OF GEODETIC SURVEYING TAPES

Empire Survey Review, 1953
Abstract The difficulty of determining the true temperature of a surveying tape when in use in the field, particularly in bright sunlight, is discussed. A simple form of resistance thermometer made of invar tape is described and the results of comparisons made between the temperatures determined by this thermometer and those recorded by mercury ...

Towards a Combination of Space-Geodetic Measurements

2011
The International Terrestrial Reference Frame (ITRF), the Earth Orientation Parameter (EOP) time series, and the International Celestial Reference Frame are obtained separately and may thus present inconsistencies. To solve this problem, a first step has been made with the latest ITRF realization (ITRF2005), which has been computed, for the first time,

Geodetic measurement of deformation in southern California

1991
The Global Positioning System (GPS) has rapidly become one of the most important geodetic tools for studying tectonic deformation. With potential 3-dimensional relative positioning accuracies better than 1 cm, GPS can monitor secular deformation as well as rapid strain fluctuations due to seismic and volcanic activity.

Navigational Methods of Measurement in Geodetic Surveying

1989
Geodesy reaches a new quality of performance with the development of computer- aided measurement systems. Compared to satellite techniques well suited for global tasks, close range area techniques are achievable with unseen accuracy and unseen sampling rates. Inertial measurement techniques based on purely dynamic principles will change the educational

Geodetic measurements in the Dixie Valley Area

Bulletin of the Seismological Society of America, 1957
abstract Resurveys made after the 1954 earthquake in the Dixie Valley Area determined the horizontal and vertical displacements which occurred. Triangulation stations on the west side of the fault moved north approximately 4 feet, and points on the east side moved south by a similar amount.

Repeated Geodetic Measurements in the Tatra Mountain

2011
For detection of horizontal and vertical movements of the Earth’s surface the repeated geodetic measurements were organized in the Tatra Mountain. Non-permanent GPS measurements with 4–5 days observation time were provided from 1998 to 2008 yearly.

Automation of Testing of Geodetic Measuring Instruments

2014
International and national standards for testing and calibration of geodetic measuring instruments specify the procedures of testing and calibration, as well as the presentation of measurements results with the estimation of measuring uncertainty. The paper presents only the international standards for testing and calibration of geodetic measuring ...
