Why can't we just task commercial imagery providers like Planet or Maxar instead of building our own constellation?

Commercial providers are bound by their home government's export-control and shutter-control regulations. Under US law, the NOAA Remote Sensing Space Policy gives the Secretary of Commerce authority to restrict imaging of specific areas during national security events — meaning your access can be cut precisely when you need it most. A sovereign constellation operates under no foreign shutter-control authority, ensuring uninterrupted tasking in any scenario your government deems critical.

What orbit should a force-movement tracking constellation use?

Sun-synchronous LEO (450–550 km altitude) is the standard choice for EO sensors because consistent lighting angles simplify change-detection analysis. SAR satellites can operate at slightly higher inclinations and are indifferent to solar angle. GEO is unsuitable for tactical imagery at useful resolutions — the physical aperture required to achieve sub-5 m resolution from 36,000 km is impractical on current launch vehicles.

How many satellites do we need for operationally meaningful revisit?

Academic modelling (ESA FAST-D, 2023) indicates approximately 72 satellites in complementary orbital planes are needed for a 30-minute global-average revisit at 500 km altitude. For a regional theatre focus — say a 2,000 km × 2,000 km area of interest — a 12–16 satellite constellation can achieve sub-45-minute average revisit at significantly lower cost, which is often sufficient for tracking mechanised force movements.

How does a SAR satellite track vehicles differently from an optical satellite?

SAR satellites emit their own microwave pulses and measure the reflected energy, making them independent of sunlight and capable of penetrating cloud cover. For force movement, analysts look for coherence change detection — comparing two SAR passes to identify pixels where the surface has changed — and for moving target indication (MTI) signatures caused by Doppler shifts from moving vehicles. SAR is slower to interpret but far more persistent than optical in contested weather environments.

What is the realistic end-to-end latency from satellite pass to actionable intelligence?

Best-in-class commercial pipelines (e.g. Capella Space's direct-downlink architecture) achieve 12–18 minutes from image capture to analyst desktop. Sovereign systems with dedicated high-latitude ground stations and AI-assisted change detection can achieve comparable latency. The critical constraint is usually analyst exploitation time, not downlink speed — automated vehicle detection algorithms are therefore a necessary complement to the space segment.

Can the data be shared with allied forces, and what standards govern that?

Yes, but interoperability requires deliberate architecture choices. NATO STANAG 4545 defines the National Secondary Imagery Format used across allied intelligence networks. MIL-STD-2525D governs how tracked objects are symbolised in shared common operating pictures. A sovereign programme designed to allied standards can contribute to coalition C2 systems without exposing raw imagery to foreign exploitation chains.

What is the minimum viable investment for a regional force-movement tracking constellation?

A credible 12-satellite regional constellation of microsatellites (100–150 kg class, mixed EO and SAR) with a dedicated ground segment and exploitation software is currently achievable for approximately $400–650 million over a five-year development and initial-operations period, based on recent comparable national programmes in Europe and the Asia-Pacific. This excludes launch costs, which add $10–25 million per dedicated rideshare mission depending on provider and orbit.

How do we protect the constellation from anti-satellite (ASAT) threats?

Distributing capability across many small satellites is inherently more resilient than concentrating it in one or two large platforms: destroying 12 of 72 nodes degrades performance by roughly 17% rather than eliminating it. Additional measures include frequency-hopping uplinks to resist jamming, encrypted command channels compliant with CCSDS security standards, orbital manoeuvre fuel margins to evade co-orbital inspection threats, and disaggregation across multiple orbital planes to frustrate simultaneous intercept.
