In the Cold War, the Arctic was a corridor for early warning and a proving ground for communications at the edge of the map. Today it is again a strategic hinge, but the decisive infrastructure is increasingly orbital: constellations that promise visibility across ice, sea, and sky, even as the polar environment exposes their limits. The paradox is simple: the region most invoked in claims of persistent monitoring is the region where persistence is hardest to engineer, easiest to overstate, and most likely to fail quietly through bottlenecks far from the sensor.
Satellites Over Snow explains Arctic surveillance as a chain of dependencies rather than a single platform. It shows how polar orbits shape revisit and viewing geometry; how ground station networks and relay pathways determine whether collected data arrives in time to matter; and why data latency is often a governance and workflow problem as much as a physics problem. Moving across imaging, communications, and positioning, Afnan Barakat clarifies the trade-offs between resolution and coverage, the realities of downlink scarcity, and the ways interference and congestion can turn "availability" into a contested resource. The book also examines how dual-use constellations blur civil and security missions, shifting power towards those who control tasking, prioritisation, and the terms of access.
Written for students, general readers, and policy and security analysts, this book offers a framework for judging surveillance claims with disciplined scepticism: What does persistence mean here? Where does latency accumulate? Which links are brittle, and which are genuinely resilient? Readers finish with a clearer understanding of how Arctic awareness is produced, how it can be disrupted without a single dramatic space event, and why the next surveillance arms race will be fought as much through systems integration and institutional control as through new satellites in the sky.
