{"product_id":"orbital-mesh-routing-engine","title":"Orbital Mesh Routing Engine","description":"\u003cp\u003e\u003cspan\u003eOMRE is a complete, production-engineered routing kernel for orbital mesh networks — the layer that decides, on every tick of a constellation's master clock, which satellite forwards each packet to which next hop. It is engineered to the standards a flight-software qualification programme demands: zero heap allocation after construction, bounded worst-case execution time, bit-identical replay, and a full audit-evidence bundle that a buyer's acceptance team can reproduce on their own hardware in under an hour.
