ABSTRACT
Spacecraft missions such a spacecraft docking and formation flying requires high-precision relative position and attitude data. Although a global positioning system (GPS) can provide this capability near the earth, deep space missions require the use of alternative technologies. One such technology is the vision-based navigation (VISNAV) sensor system developed at Texas A&M university .J comprises an electro optical sensor combined with light sources or beacons. This patented sensor has an analog detector in the ....etc

VISNAV

The VISNAV system uses a Position Sensitive Diode (PSD) sensor for 6 DOF estimation. Output current from the PSD sensor determines the azimuth and elevation of the light source with respect to the sensor. By having four or more light source called beacons in the target frame at known positions the six degree of freedom data associated with the sensor is calculated.

The beacon channel separation and demodulation are done on a fixed point digital signal processor (DSP) Texas Instruments TMS ....etc

Hello Sir, i'm Vivek a student of final year BE. I need a power point presentation of Vision Based Navigation System (VISNAV). I need this presentation for the purpose of seminars. The following is the abstract of the topic which i choose from (http://seminarsprojects.in).

Abstract:-
Now days there are several navigation systems for positioning
the objects. Several research efforts have been carried out in the field of
Six Degrees Of Freedom estimation for rendezvous and proximity
operations. One such navigation system used in the field ....etc
