GrandTour
Description:GrandTour is Freeware program for Windows developed by John D. CallahanGRANDTOUR can simulate expanse as seen from the Voyager and Giotto spacecraft. In joining, GRANDTOUR can generate scenes from arbitrary points in expanse or the Earth, with the spacecraft visible to the observer. The planet, moons, and rings of concern (or comet, nucleus, and tail), stars, the sun, and the spacecraft are all accurately fatigued with wireframe representations. Hidden line removing is done for the body surfaces. The motions of the bodies themselves are well accurate, with errors no greater than 500 kilometers. The user has considerable steer over the time footstep, pasture of prospect, etc., and many frames per second are typically generated. The program was originally developed at the Jet Propulsion Laboratory by John D. Callahan to second in the analysis of branch and optical navigation figures. In joining, the program was filmed by the BBC as allotment of a NOVA documentary on the Voyager Uranus encounter, and by the Four Point Entertainment Company for a commercially available video on Halley's Comet.
