3D Earth, hexagons by Hierarchical-Hexagonal-Geospatial-Indexing-System (H3) cell. Each populated cell carries the Dual-In-line-Memory-Module (DIMM)s reporting from that geographic point.
Colored markers are the ~50 government NMDB neutron monitor stations — cyan = polar / solar-sensitive, red = equatorial / galactic-only. Our sensor hexes complement that fixed network with a denser participant grid.
Click any hex (populated or empty) to fly the camera there and open its drawer. Press n or the hop button to cycle through populated hexes; b or the ← button walks them in reverse.
Real-time poll of /global/now drives the populated hexes. Altitude shells (ground / troposphere / stratosphere / LEO / MEO+GEO) toggle from the right HUD. Deep-link any hex: the URL carries ?cell=<h3-id> so a refresh or share lands the recipient on the same focus.
