Research on magnetic declination in Lithuanian territory

open access: yesAviation, 2008
Magnetic declination is the angle between the planes of the astronomic and magnetic meridians. Magnetic declination is used in navigation, geophysics, geodesy, cartography, geology, and other fields.

Effects of neutral wind on the electron temperature at a height of 600 km in the low latitude region [PDF]

open access: yesAnnales Geophysicae, 1996
Electron temperature observed by the Hinotori satellite with the low inclination at the height of ~600 km was studied in terms of local time, season, latitude, magnetic declination and solar flux intensity during a 16-month period from 1981 to 1982 ...

Magnetic declination of the territory of Ukraine: the results of observations and calculations

open access: yesГеофизический журнал, 2015
A technology is proposed for calculating the strength and angular components of the vector of the induction of the Earth's magnetic field. The technology is based on the development of a three-dimensional model of the earth's crust and the calculation of

A possible effect of atmospheric circulation in the daily variation of the earth's magnetic field [PDF]

open access: yes, 1963
The daily variation of the horizontal intensity of the earth's magnetic field at Honolulu exhibits seasonal features that are not related in a simple way to solar declination.

A search for extended radio emission from selected compact galaxy groups [PDF]

open access: yes, 2017
Context. Studies on compact galaxy groups have led to the conclusion that a plenitude of phenomena take place in between galaxies that form them. However, radio data on these objects are extremely scarce and not much is known concerning the existence and

Optimization of magnetic anomaly detection with single-axis sensor for pig locating in low latitude areas

open access: yesPetroleum, 2019
When a pig mounted with permanent magnets gets stuck in the pipeline, it can be located by detecting the magnetic anomalies on the ground using a single-axis magnetic sensor.
