Abstract:	The approach navigation phase of planetary flight is used to assess the accuracy of the midcourse guidance operations and to provide the information required to determine the desirability of a trajectory correction prior to fly by or capture. In this investigation, a study of navigation system requirements for this phase of space flight is made. A navigation technique consist with the use of optical sensors and a large number of measurements is approach to Mars, is used to determine, quantitatively, the effects of variation in the sensors accuracy and the effects of two kinds of data processing filters on the performance of navigation process.
