The theory is also very useful for other applications such as mission analysis.

Abstract:

Early in 1987, the Bell Aerospace/Textron Gravity Gradiometer Survey System (GGSS) will be tested by the Air Force Geophysics Laboratory in an airborne survey of a 300 × 300 km region of Oklahoma and Texas. The survey pattern will be a grid with a 5 km separation between adjacent tracks, both north‐south and east‐west. One way to process the GGSS survey data is to analyze an electrical network that is isomorphic to the survey network. The integrated gradients between the nodes where the survey lines cross correspond to the applied voltages between the nodes of the electrical network; the gradi

Abstract. The postglacial uplift and surrounding subsidence in Scandinavia is well described as close to regular, and the phenomenon is similar on timescales of tens, hundreds and thousands of years studied via geodesy, seismology and geology.

Abstract:

When performing high-precision geometric leveling on geodynamic and technogenic polygons, the problem of selecting a system of heights and obtaining reliable data arises, taking into account, first of all, the heterogeneity of the gravitational field along the lines of leveling. The research and development of a methodological approach to solve the above issues is the purpose of this publication. For the research process, the method of mathematical processing of a wide spectrum of geodetic and gravimetric measurements, differential and mathematical analysis, methods of conducting high-precisio

Abstract:

The influence of static loadings of the foundations of structures in the process of soil compaction of the base on the subsidence of the soil surface and the bench outside the loaded contour is considered in the work. The studies were performed on models of rectangular massive foundations using the method of equivalent soil layer, based on the theory of compaction of linear-deforming half-space. Using this method, the values of the average sedimentation of the models of rectangular foundations were calculated, taking into account all components of normal stresses and lateral soil extension.

Abstract:

In the early spring an effort was made to extend some lines of marine gravity data from the shelf into the coast north of Ammassalik. A net of marine gravity data covers the shelf off East Greenland, reaching from about 59°N to 74°N (fig. 1). South of Scoresby Sund the gravity data are mostly coIlected in regions floored by oceanic crust, though some of the lines cross the ocean-to-continent boundary. Between Ammassalik and Scoresby Sund the oceanto-continent transition zone (OCT) runs dose to the coast (Larsen, 1984), and is probably related to the onshore Tertiary basaltic dyke swarm describ

We present a detailed map of ground movement in Italy derived from the combination of the Global Navigation Satellite System (GNSS) and Satellite Synthetic Aperture Radar (SAR) interferometry. These techniques are two of the most used space geodetic techniques to study Earth surface deformation. The above techniques provide displacements with respect to different components of the ground point position; GNSSs use the geocentric International Terrestrial Reference System 1989 (ITRS89), whereas the satellite SAR interferometry components are identified by the Lines of Sight (LOSs) between a sate

Abstract:

The new approach for measuring the flatness of floors or other horizontal surfaces is based on the use of vehicle-mounted sensors that moves through these surfaces in a more or less automated way. It becomes competitive in relation to the classical methods using the straightedge and the wedge or tilts or geodetic methods used interchangeably. The measurement with vehicles requires, on the one hand, the movement of the sensors along the set lines, and on the other - the appropriate frequency and precision of the readings. Research and implementation works on the implementation of kinematic tach

Abstract:

Since the very beginning of the Itapetinga 45-ft antenna operations in 1971, there were plans to use it as a southern hemisphere VLBI terminal for high north-south resolution. The first successful VLBI tests were performed on water vapor lines in cooperation with Haystack Observatory in 1978 in one of the last runs using the MkI system. This cooperation led to the construction of a MkII terminal for Itapetinga years later (1981–1983). Astrophysical VLBI runs have been carried out since 1984, with the cooperation of Caltech, producing maps of unique resolution on stronger quasars, especially on

Preservation of this degree of accuracy in derived products is far from straightforward and may leave vast room for trouble in the different steps involved in the collection, storing, processing, analysis, and delivering of geospatial information.

Abstract:

With the increase in satellite communication interference, the tri-satellite time difference of arrival (TDOA) localization technique, which is an effective method to determine the location of the interference using sensors or antennas, has been developed rapidly. The location of the interference source is determined through the intersection of the TDOA lines of position (LOP). However, when the two TDOA LOP have two mirrored intersection points, it is theoretically difficult to determine the real location. Aiming at this problem, a method for eliminating mirrored location based on multiple mo
