PANGU is a powerful set of tools for modelling the surfaces of planetary bodies such as Mars, the Moon, Mercury and asteroids using real and synthetic data. It has the ability to generate visual, thermal infrared, LiDAR and RADAR images from any position and orientation. These images can be used for off-line and closed-loop simulations of planetary landing, surface roving and in-orbit rendezvous operations. The position and orientation of the camera, the Sun and other bodies can be specified directly for each image or obtained via SPICE kernels using just the date and time of interest.

PANGU is designed to provide a high degree of realism while operating at near real-time speeds on modern desktop PCs with graphics cards that support OpenGL 3.0 and programmable GPU shaders. A selection of videos of a various different scenarios created using PANGU can be found on the videos page (contains links to YouTube).

A three page brochure about PANGU (PDF) provides a summary of key features.

The paper Planetary surface image generation for testing future space missions with PANGU (PDF) was presented at the 2nd RPI Space Imaging Workshop in Saratoga Springs, NY (28-30 October 2019).
