Why can't we just subscribe to a commercial SSA data feed instead of building our own?

Commercial providers such as LeoLabs, ExoAnalytic Solutions, and Slingshot Aerospace offer excellent catalogue data for peacetime operations. However, their terms of service, export-control restrictions (US ITAR/EAR), and commercial priorities mean that data can be degraded, delayed, or withheld during exactly the geopolitical crises when a sovereign nation needs it most. Owning the sensors and the data pipeline removes that dependency entirely and allows classification of warning intelligence at the appropriate level.

What is the difference between Space Situational Awareness (SSA) and Space Indications & Warning (I&W)?

SSA is the broad capability to track, catalogue, and characterise objects in orbit — it is largely a peacetime, safety-oriented function. Space I&W is a subset focused specifically on detecting threatening behaviour: unusual manoeuvres, active RF emissions consistent with jamming, shadowing of friendly satellites, or pre-attack positioning. I&W feeds decision-makers and can trigger escalatory or protective responses, making it a distinctly defence-intelligence function that requires higher classification and faster dissemination pipelines.

How many satellites does a meaningful sovereign I&W constellation require?

Architecture studies by ESA and national defence agencies suggest a minimum of 12–20 LEO optical/radar microsatellites to achieve sub-2-hour revisit on high-priority orbital regimes, with additional payloads needed for GEO and MEO coverage. A phased programme might begin with 6 pathfinder satellites to demonstrate on-orbit behaviour forensics before scaling to full capability. The exact number depends heavily on orbit selection, sensor aperture, and the threat orbits a nation prioritises.

What orbits do adversary ASAT systems typically operate from, and does that affect sensor design?

Kinetic kill vehicles and co-orbital ASATs have been tested and deployed in LEO (e.g., the 2021 Russian Nudol test, the 2007 Chinese SC-19 test). Directed-energy and jamming systems can operate from GEO or the ground. An effective I&W architecture therefore needs both LEO-resident sensors for proximity monitoring and ground or space-based assets with GEO visibility. This multi-regime requirement drives sensor diversity — optical telescopes for GEO, radar for LEO debris and manoeuvre detection.

How does Space I&W integrate with a nation's missile warning systems?

Missile Warning satellites (typically GEO infrared) detect launch plumes but cannot characterise on-orbit threats. Space I&W fills the gap by monitoring whether adversary satellites are manoeuvring to blind or destroy those very missile warning assets. The two functions share common ground-infrastructure, command-and-control interfaces, and threat-assessment workflows, which is why Satellize treats them as adjacent capabilities with significant architectural overlap.

What legal framework governs offensive actions detected through I&W?

There is no binding treaty specifically governing ASAT operations or space warfare. The 1967 Outer Space Treaty prohibits weapons of mass destruction in orbit but is silent on conventional co-orbital attack. The UN COPUOS Long-term Sustainability Guidelines (2019) are non-binding. NATO has declared that attacks on allied space assets can trigger Article 5 collective defence, but the threshold and attribution burden remain undefined. Sovereign I&W data is therefore both an operational necessity and a legal-evidence asset in any future diplomatic or enforcement response.

Can a small or middle-power nation afford a sovereign Space I&W capability?

A full-spectrum constellation is expensive, but a credible minimum viable capability — a 6-satellite optical monitoring constellation in LEO plus a national data-fusion centre — can be fielded for approximately $150–300 million over a five-year programme, well within the defence budgets of mid-sized NATO or ASEAN members. Pooling with like-minded allies (as EU members do through the EU SST Consortium under the EU Space Programme) can reduce per-nation cost by 40–60% while preserving national data sovereignty through bilateral sharing protocols.

How quickly must a Space I&W system generate an alert to be operationally useful?

Analysts at the US Space Force and in published ESA studies suggest a decision-useful warning must reach the national command authority within 30–60 minutes of anomaly detection for LEO threats, and within 4–6 hours for GEO-regime events where the threat timelines are longer. This requires on-board edge processing to pre-classify manoeuvre signatures, encrypted low-latency downlink (ideally inter-satellite crosslinks to a national gateway), and automated fusion with ground-based intelligence — none of which a third-party commercial service is contractually obligated to provide on a nation's schedule.
