Why can't we just buy capacity on a commercial provider such as Inmarsat, Viasat, or SES when we need it?

Commercial providers operate under the laws of their home jurisdiction and can be directed by their governments to suspend, redirect, or degrade service — including to foreign military customers. Ukraine's experience in 2022 illustrated both the value of commercial SATCOM and the risks of dependency on a single provider's commercial terms and political calculus. A sovereign constellation gives national command authority the legal and physical ability to operate independently of any third-party policy decision.

How many satellites does a resilient command network actually need?

A minimum viable constellation for regional continuous coverage typically requires 6–9 microsatellites in a carefully inclined LEO shell. Full global coverage with meaningful redundancy (N+2 spares per orbital plane) generally demands 18–30 satellites. The right number depends on the required revisit time, the geographic area of operations, the minimum elevation angle at which the terminals can maintain a lock, and the acceptable probability of link outage during a worst-case conjunction.

What frequency bands are most suitable, and who allocates them?

X-band (8–12 GHz) is the established government and military standard, offering a balance of rain-fade resilience and bandwidth. Ka-band (26.5–40 GHz) provides higher throughput for data-heavy command-and-control but degrades in heavy precipitation. The ITU allocates spectrum through its Radio Regulations, and nations must file with the ITU Radiocommunication Bureau under the procedures of Article 9 to gain protected status. UHF remains essential for anti-jam and nuclear-survivable communications under ITU-R M.1450 guidelines.

How is the link secured against interception and spoofing?

A robust architecture layers multiple controls: AES-256 payload encryption (per FIPS 140-3 certified hardware), authenticated frequency-hopping spread-spectrum waveforms to defeat jamming and interception, mutual PKI-based terminal authentication, and physically separate uplink/downlink frequency pairs. For the most sensitive traffic, nations typically apply Type 1 encryption using nationally certified cryptographic modules — which is itself a key area where supply-chain sovereignty must be evaluated separately.

Can a microsatellite constellation survive an adversary's jamming campaign?

No architecture is jam-proof, but a well-designed LEO constellation with spread-spectrum waveforms, high-gain directional antennas on the terminals, and frequency agility is substantially more resilient than a single GEO transponder. The geometry also helps: LEO satellites move quickly across the sky, making sustained spot jamming from a fixed ground station much harder than jamming a stationary GEO link. Multi-path routing through multiple simultaneous satellite contacts further reduces single-point vulnerability.

What is the build-versus-buy decision point from a cost perspective?

A 12-satellite microsatellite command-relay constellation, including ground segment and five years of operations, typically costs $80M–$200M depending on the nation's industrial base and technology readiness. A decade of commercial capacity at comparable throughput and availability could cost $150M–$400M, with no residual asset and ongoing foreign dependency. The break-even horizon is typically 6–10 years; beyond that, the sovereign programme almost always wins on total cost of ownership — and delivers capability that cannot be switched off by a foreign board or regulator.

How do we handle the reconstitution risk if satellites fail or are destroyed?

Resilient design requires both on-orbit redundancy (spare satellites in each plane) and a responsive launch agreement with a national or allied launch provider that can deliver a replacement payload within 72 hours of a go-order. DARPA's Blackjack and ESA's Space Rider programmes have both demonstrated that responsive LEO reconstitution is technically achievable. Nations should also consider disaggregated payloads hosted on commercial satellites as a diversified backup layer.

What role does the ITU play, and can military satellites avoid ITU coordination?

All satellite transmissions, including military ones, are subject to ITU Radio Regulations under international treaty obligations. Military satellites are not exempt; they are handled under the same filing procedures as civil systems, though member states have some latitude in how much technical detail they disclose. Skipping coordination does not make interference legal; it simply means a nation forfeits its priority claim and is obligated to accept interference from systems that did coordinate. Most nations use diplomatic channels in parallel with the ITU process to accelerate clearance for sensitive military frequencies.
