Goddard 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.
