This work reviewed the state of the problem of navigating the various civilian and military objects with the help of satellite navigation systems. Global satellite navigation systems (GNSS) already occupy a leading role in the navigation of objects in all sectors of transportation, warfare, and many others. Their extensive use, together with the indisputable advantages, showed significant disadvantages, such as influence of atmospheric factors, electromagnetic disturbance emitted by a variety of devices, vulnerability of electromagnetic jamming of satellite signal, etc. This state of navigation methods now led to the rapid development of new complex methods for reliable navigation. In the work are examined the main methods for reliable navigation of civilian and military objects, which are being developed in different countries. There has been proposed a model of integrated navigation system for the needs of rail transport, consisting of external sensors and navigation sensors for internal navigation accounted with respect to the navigated object.
