Goddard Image Analysis and Navigation Tool (GIANT)(GSC-18758-1)

The Goddard Image Analysis and Navigation Tool (GIANT) is an API for performing various kinds of optical navigation (OpNav) through python scripts. It provides the necessary tools for the most common OpNav tasks, including geometric camera calibration, camera attitude estimation, target center finding, surface feature navigation, and more and makes it easy to add new capabilities through the modular components it exposes. GIANT is mature and flight proven, having been used throughout the OSIRIS-REx mission in an independent verification and validation (IV&V) role with great success.
