Anybody who has been on the open sea without visual clues for orientation or, worse, trapped in the dark by a sudden failure of the lighting system, knows how easy it is to feel lost. If a navigation system is available, then there is a means to calming down and finding your way.
The first results in the design of an automatic DIM are presented. This instrument should be completely operational in 3 years. By associating it with other instruments which are already automatic, like variometers and proton magnetometers, it will be possible to install absolute magnetic observatories, all around the Earth, even in inaccessible places like on islands and on the ocean floor,...
The Republic of Macedonia, formerly part of Yugoslavia, has taken the initiative to call on the expertise of both scientific researchers in geomagnetism (modelers, cartographers, surveyors and, geophysicists) and aeronautical experts (pilots, aircraft operators, and airport managers) to improve aeronautical and airport safety.
We present our geomagnetic repeat station work in the Republic of Macedonia performed during the years 2002, 2003 and 2004. A total of 15 stations were established. New stations were created as the localization data of the old stations were not available at the time. The paper will describe the measuring and localization equipment used, the observation techniques applied and the way the data...
Flying safely in aircraft implies the use of navigation instruments. Among them, the magnetic compass is still a first choice for orientation and it is compulsory in all aircraft. In our increasingly sophisticated but fragile world of global navigation systems and gyroscopic sensors, the compass is especially useful as a back-up: it is highly reliable and likely to survive in harsh electromagnetic...
The paper provides a snapshot of the global geomagnetic observatory network at the time of the Sopron IAGA Assembly in August 2009. The need for these observatories is explained and the evolution and outlook of the observing techniques are examined. We present three projects addressing the upgrade of existing observatories, the creation of new ones and the problems of observing in the oceanic regions.
