Why can't we just subscribe to a commercial imagery service like Planet or Maxar instead of building our own satellite?

Commercial subscriptions give you imagery when the vendor decides to task their satellite over your area of interest — and only for as long as the contract holds. In a conflict or sanctions scenario, a US-headquartered vendor can be legally prohibited from delivering imagery to your forces under International Traffic in Arms Regulations (ITAR) or Export Administration Regulations (EAR). A sovereign constellation answers to your chain of command, not a commercial sales team or a foreign export-control regime.

What resolution do we actually need for tactical map production?

NATO STANAG 3809 and most allied doctrine align on 0.5 m GSD for feature extraction at the 1:5,000 scale used by battalion and below. For route planning at brigade level, 1–2 m GSD is workable. The good news is that microsatellites in LEO at 500 km altitude can achieve 0.5 m GSD with a 200 mm aperture — a payload that fits on a 100 kg platform, well within the cost envelope of a sovereign programme.

How quickly can a sovereign constellation update a tactical map after tasking?

A six-satellite LEO constellation at 500 km in a sun-synchronous orbit achieves roughly 4–6 hour revisit over most mid-latitude theatres. With a forward ground station or direct-to-brigade downlink terminal, raw imagery can be orthorectified and merged into a MGCP-compliant tile within 30–45 minutes of acquisition. Compare that to the 72–96 hour update cycle documented by USGS for forces relying on pre-existing commercial mosaics.

Do we need both optical and SAR satellites?

Operationally, yes. Optical at 0.5 m GSD gives analysts the visual interpretability needed for map feature extraction and change detection. SAR — X-band preferred, as used by ICEYE and Capella — penetrates cloud and provides coherent change detection for terrain deformation, flooding, and buried infrastructure. A blended two-system architecture (optical microsats + SAR nanosats) is more resilient than either alone and is within reach of mid-tier defence budgets at roughly $300–500M for initial constellation.

What ground infrastructure do we need to use sovereign satellite imagery tactically?

At minimum: one primary ground station for routine downlink and command/control; at least one forward-deployable X/Ka-band terminal (vehicle-mounted, <500 kg) for in-theatre downlink; an orthorectification and tile-production server cluster (on-premise or edge cloud); and integration with your existing C2 GIS platform (typically ArcGIS Defence or QGIS-based). The processing pipeline should comply with OGC standards so tiles are immediately ingestible by allied NATO systems.

How does a sovereign programme handle spectrum coordination to avoid interference?

All satellite transmissions must be filed with the ITU under the Radio Regulations coordination procedure (Article 9 and Appendix 30B where applicable). Your national ITU administration files the network on your behalf; coordination with adjacent operators typically takes 12–18 months. For tactical downlinks in a contested environment, your ground terminals should support frequency-agile operation across multiple ITU-coordinated channels, and the satellite should carry a software-defined radio payload to allow in-orbit retasking of downlink frequencies.

Can a small nation afford a sovereign tactical mapping constellation?

A credible four-to-six satellite optical microsatellite constellation — including launch, ground segment, and five years of operations — can now be procured for $150–300M, depending on GSD requirements and ground station complexity. That is less than the 10-year licensing cost of a full-coverage commercial imagery subscription for a theatre-level operation. ESA's FAST (Future Advanced Satellite Technologies) programme and bilateral arrangements with launch providers like RocketLab or SpaceX further reduce cost for smaller nations willing to use standard platforms.

What happens to our maps if the constellation is attacked or jammed?

Resilience design should include orbital dispersal (multiple orbital planes), encrypted uplink/downlink (AES-256 minimum, CCSDS 355.0-B-1 for space data link security), and onboard autonomous mode in which the satellite continues imaging on a pre-loaded schedule if ground contact is lost. Redundant ground stations — at least two geographically separated — and cross-link capability between satellites further harden the architecture. A sovereign programme lets you mandate all of these; a commercial subscription cannot.
