GPS-Enhanced Onboard Navigation System (GEONS)
GEONS is a flight software package that provides onboard orbit determination and control in real time, with higher accuracy, without human intervention, and while requiring minimal onboard computing resources. It substantially improves definitive and predictive accuracy of Global Positioning System (GPS) receiver point solution fixes, achieving accuracies of at least 20 meters and 3 cm/sec.

Recursive Hierarchical Segmentation (RHSEG) Pre-Processing Software
The RHSEG software provides hierarchical segmentation (pre-processing) of image and image-like data. The software significantly improves the extraction of patterns from complex data sets and is optimized for speed and accuracy. This algorithm provides the user with precise control for selecting the desired level of detail from the hierarchy of results.
