Inertial navigation tracks the position of an object by measuring and comparing the distance it travels with the accelerations in various directions it experiences while moving. For clarification, gyroscopes are used that, once spun up, tend to remain in one position (like the gyroscopes we played with as kids). When the gyroscope position is moved, sensors detect the direction, speed, and duration (vector) of the movement which is then calculated to determine a resultant change in position of the gyroscope. Inertial Navigation Systems (INS) have a built in error due to the precessing (caused by the earth's movement) that all gyroscopes experience. In aircraft, this error can be as much as a half a mile per hour. Over a 5 hour flight, for instance, an INS could be 2.5 miles off and still be considered good. By comparison, a GPS over the same period of time will usually have an accuracy of 30 yards or less. For this reason, and the fact that inertial navigation systems are quite expensive, INS is no longer considered state of the art technology.

the disadvantages is it need to give data before flight

Inertial Navigation System (INS) refers to a system based on dead reckoning, that integrates several sensors in order to calculate your position. If you know your previous position,lets say 1 second ago, and you know your speed and direction then you can determine where you are now. An inertial reference system, in terms of geodesy refers to a coordinate system that does not move with the Earth, it has its axis oriented to fix points outside of Earth. Inertial Reference coordinate systems are used for position of bodies outside of Earth

I would not have a clue
The basic principle in Navigation is to plot the path from where you are, to where you wish to go. This would be practiced by backpackers, ship's Captains, Aircraft, etc. You will probably use some instrumental aid, such as map and compass, a GPS system, an inertial navigation system, and so on.
The function of a navigation satellite is to provide direction for people who sail or fly. It will rely on GPS to give direction guidance.
