The O1 is a large-format aerial photogrammetry rig: one 150MP nadir camera plus four 150MP oblique cameras (33°x25° FOV, 90mm focal length) capture a full 3D city model in a single pass, feeding urban planning, pipeline routing, 2D mapping and DSM/DTM production at scale. An integrated Applanix IMU-46 and 50Hz Trimble BD992 GNSS keep every frame precisely positioned, and five 2TB SSDs (around 3 hours of recording) handle the resulting data volumes. At a typical flying height of 665m AGL it resolves down to roughly 5cm ground sample distance. At 48-66kg depending on configuration, this is a serious aerial payload aimed at survey firms and local authorities running city-scale digital twin or urban-planning projects rather than single-site work.
