It is well known that geomagnetic field varies in time, as well as in space. Besides, the world magnetic models which are the main sources of information concerning the values of geomagnetic field elements in a particular place, we present more precise and accurate model of these elements covering the territory of Bulgaria. Our study uses information from the last absolute geomagnetic survey involving measurements in 473 points, secular data from Panagyurishte (PAG) and several other Intermagnet observatories near Bulgaria, as well as secular magnetic measurements of the Bulgarian network.
Above and beyond the scientific investigation which are performed using geomagnetic field values, this information has also practical application. The most significant element is the geomagnetic declination, which is widely used in geodesy, cartography and their associated navigational systems. The geomagnetic declination is very important for navy and aviation (civil or military), radio connections, etc. As the geomagnetic field changes with time, the topography maps has to be updated regularly. Each edition must have a reliable value of the geomagnetic declination to allow orientation with the help of a compass. Present paper gives most up-to-date models of the total geomagnetic field (F), horizontal component (H) and declination (D) over the whole territory of Bulgaria determined for the 2020.0 epoch. The observatory measurements, existing records and calculations of geomagnetic field elements are also described. |
