Space Navigation


in the broad sense, control of the motion of a spacecraft; in a narrower meaning, the navigational problem is the determination of the location of a spacecraft and the projection of its motion as a mass point. The system that performs these functions (the space navigation system) usually includes on-board and earth-based measuring and computing equipment. The astronaut may participate in solving problems of space navigation.
