Abstract
The invention relates to navigation, particularly, to detection of indoor and outdoor positions of mobile devices. Technical result of the invention is to improve the accuracy of mobile terminal position detection at time of occurrence of a specific trigger event and decrease of load on sensor, computing, communication and other resources of the mobile terminal at times when a trigger event occurs. Mobile terminal positioning technique at the trigger event moment, is characterized by the following sequence: receipt of series of readings of inertial and non-inertial sensors, identification of intervals, during which readings of at least one sensor generates a stationary process; then detection of at least one point of time, when at least one stationary process is replaced by another stationary process; then identification of parameters of at least one pattern of movement for at least one stationarity interval; then detection of at least one position of the mobile terminal according to readings of non-inertial sensors; estimation of mobile terminal path according to parameters of at least one pattern of movement and then of position corresponding to change of one stationary process to another; then detection of mobile terminal position at time corresponding to a specific trigger event.
