GENA is a robust non-linear least-squares generic network adjustment engine. With GENA, geodetic networks, photogrammetric and remote sensing blocks and any other type of network can be adjusted. Observations of different types can be arbitrarily combined into single large adjustments.
GENA is, as well, a simulation tool. It can be used to help design geomatic measurement instruments; in particular, remote sensing sensors and multi-sensor systems. It can be used to help design measurement campaigns.
