📡 Low-Earth-Orbit Broadband Constellation Lab: Coverage, Latency, Handover and Capacity

Walker-delta LEO shell on a Blender-built globe: coverage and visible satellites versus latitude, slant-range latency, handover policies, Doppler, link budget with rain fade, laser-link versus fibre routing and cell capacity with contention. Inspired by publicly described ~550 km, 53 degree broadband constellations; the network-performance companion to the catalogue's constellation geometry sims.
