Aid Distribution Routing

Using satellite imagery, terrain data and real-time weather feeds to compute and update optimal aid convoy routes through disaster-affected or conflict-degraded terrain.

When a cyclone, earthquake or armed conflict disrupts a country's road network, the standard logistics playbook collapses within hours. Bridge washouts, blocked mountain passes and shifting front lines make yesterday's route plan actively dangerous today. National disaster-management agencies that rely on commercial mapping services or foreign humanitarian operators for routing intelligence are permanently reactive — they learn about road failures from drivers who are already stuck, not from overhead sensors that saw the blockage forming.

A sovereign satellite stack changes that calculus. Optical and SAR imagery at sub-5-metre resolution reveals passable versus impassable road segments; SAR in particular cuts through the cloud cover that invariably accompanies cyclones and monsoon flooding. Fused with GNSS-derived terrain models and short-range weather forecasts downlinked from the nation's own meteorological constellation, a routing engine can recalculate convoy itineraries every few hours and push updated waypoints directly to field vehicles and supply-hub coordinators. The decision cycle compresses from days to under two hours.

The operational outcome is measurable: fewer convoys diverted into dead ends, lower fuel burn per tonne delivered, faster last-mile throughput to population centres, and — critically — a national operations picture that the government owns and controls. Aid organisations working within the country can be given read access to the same common operating picture on the government's terms, rather than the reverse. Sovereignty over the data means the state directs the response rather than coordinating around it.

What matters

Road-segment passability changes within hours after a major flood or earthquake; a 12-hour revisit gap makes routing data operationally stale before it is acted on.
SAR imagery is the only reliable source of ground-truth road condition during the cloud-obscured first 72 hours of a tropical cyclone response — the window when aid access is most contested.
Foreign commercial routing services have suspended or throttled data access to sanctioned or conflict-affected states at exactly the moments those states needed the capability most.
A convoy diverted by bad route intelligence in mountainous terrain can add 4-8 hours of travel time per leg, directly degrading the cold-chain integrity of medical supplies.

Sovereignty score: 8/10 — A nation that depends on foreign satellites or commercial data brokers for its disaster-routing intelligence has outsourced the command tempo of its own emergency response to entities with no accountability to its citizens.

Commercial providers — including Planet, Maxar and Airbus — apply export-control and end-user-certificate constraints that can delay or block data delivery to states under US, EU or UN sanctions regimes, creating a gap precisely when vulnerability is highest.
Foreign humanitarian operators granted routing-data primacy during a response effectively assume coordination authority over the national logistics network, displacing government agencies and eroding sovereign accountability for aid delivery outcomes.
A national SAR and optical constellation generates the persistent, high-cadence coverage needed for route monitoring; relying on tasking requests to third-party commercial constellations introduces 24-48 hour latency that is operationally unacceptable in fast-moving flood or conflict scenarios.
Routing data derived from sovereign sensors can be classified or access-tiered by the government — shared with approved NGO partners while withheld from actors whose presence in conflict-affected areas creates force-protection risks.

Reference architecture

Payload: Dual payload per satellite: (1) optical imager, 3m GSD, 40km swath, RGB+NIR; (2) X-band SAR, 5m stripmap resolution, 50km swath — SAR enables all-weather, day/night road-condition sensing
Bus class: 16U cubesat bus, ~28kg, 120W payload power — optical and SAR share a single bus via time-division operation; SAR pulse compression handled on-board to reduce downlink volume
Orbit: Sun-synchronous LEO at 520-560km; 18-satellite walker constellation delivering sub-4-hour revisit over the national territory; dual-plane launch cadence to accelerate initial coverage
Ground segment: Primary mission operations centre co-located with the national disaster management authority; two regional downlink stations (S-band TT&C, X-band payload data); SatNOGS UHF/VHF backup for housekeeping telemetry; automatic scene-triggered downlink on approach to national ground mask
