The article represents the methodology for estimation of the Earth’s magnetic field characteristics for a particular area. It is proposed to use a group of sensors inside of a tablet or a cell phone as a measurement device. We used typical sensors raw data like pitch, roll, yaw (from gyros); components of magnetic field intensity vectors (from magnetometers); latitude, longitude, altitude (from global positioning sensor). We represent the result of intensity vector components estimation for particular area. It is stated that the most important characteristics of magnetic fieldare horizontal and vertical components of intensity vector and inclination and declination angles. In addition, we compared the received results with magnetic field forecast, according to the world magnetic model.
