Urban freight is invisible to most city governments. Delivery vans, cargo bikes and micro-fulfilment shuttles generate a significant share of urban congestion and kerbside conflict, yet municipal authorities typically learn about this load only through carrier self-reporting — data that is incomplete, delayed and commercially curated. Without an independent ground-truth, planners cannot price loading zones correctly, enforce time-windows, or quantify the carbon footprint of the last mile.

A constellation of sub-metre optical microsatellites combined with an RF survey payload gives a city an independent, continuous read on delivery activity. Repeated passes over commercial corridors detect vehicle accumulation at kerbsides, dwell times, double-parking events and the emergence of new informal staging areas near fulfilment hubs. Optical detections are cross-correlated with RF signatures from fleet telematics bands (433 MHz, 868 MHz, 915 MHz LoRa/Sigfox, and cellular LTE-M) to distinguish delivery vehicles from private cars and to attribute detections to vehicle class.

The operational outcome is a dynamic freight heat-map that city logistics teams update daily without touching a single carrier API. Planners can identify which streets absorb disproportionate dwell load across morning and afternoon windows, target enforcement resources, and model the effect of kerbside pricing changes before implementation. Aggregate emissions estimates — derived from vehicle class, dwell duration and engine-state inference — feed directly into national urban air quality reporting obligations.

What matters

Carrier self-reported GPS traces are commercially sensitive and routinely withheld from regulators, making independent satellite observation the only neutral data source.
Double-parking by delivery vehicles reduces effective lane capacity by up to 25% on dense commercial streets, a cost that only becomes quantifiable with independent dwell-time measurement.
Urban freight accounts for roughly 20–30% of city-centre CO₂ emissions; satellite-derived vehicle-class and dwell data are required to construct credible national inventory figures.
Sovereign control of the observation record prevents major e-commerce and logistics platforms from gaming or withholding data during regulatory negotiations over loading-zone access fees.

Sovereignty score: 7/10 — A government that depends on commercial carriers for freight data surrenders its ability to regulate, tax or carbon-account the last mile independently.

Major logistics platforms have withheld or anonymised kerbside dwell data during negotiations over road-pricing and loading-zone reform in multiple EU and Asian cities, demonstrating that regulatory leverage requires an independent observation capability.
National urban air quality directives (EU Air Quality Directive 2024/2881, WHO guidelines) impose legal liability on governments for accurate freight emissions inventories; carrier-supplied data carries no audit trail and cannot satisfy statutory evidential standards.
Supply-chain dependency risk: commercial Earth observation providers that supply freight analytics are predominantly US- or EU-headquartered and subject to export controls and service-suspension clauses that could remove access precisely when a city is in conflict with a major logistics operator.

Reference architecture

Payload: Dual payload per satellite: (1) optical imager, 0.7m GSD panchromatic / 2m multispectral, 12km swath, for vehicle detection and classification; (2) RF survey receiver, 400 MHz to 2.7 GHz covering LoRa 868/915 MHz, LTE-M 700/900 MHz and fleet UHF bands, 800m CEP geolocation accuracy using time-difference-of-arrival across a three-satellite formation
Bus class: 12U cubesat bus, ~24 kg wet mass, 80W payload power, deployable solar panels; formation flying with 15–30 km cross-track separation for RF TDOA; optical and RF payloads share a common downlink at X-band 8.025–8.4 GHz
Orbit: Sun-synchronous LEO at 520–550 km, 10:30 and 13:30 local-time descending node pairs to capture both morning and afternoon delivery peaks; 18-satellite walker (6 planes × 3 satellites per plane), yielding 90-minute global revisit and 3–4 passes per day over target cities
Ground segment: 2-station national network (X-band receive, S-band TT&C) co-located with the national meteorological or geospatial authority; SatNOGS UHF/VHF backup for housekeeping; ground stations positioned to maximise contact windows over the primary urban coverage zones
