Resilient Mesh Backhaul

Providing unkillable, satellite-routed data backhaul that stitches dispersed ground nodes into a coherent tactical network when terrestrial links are severed or jammed.

Modern land forces operate in disaggregated formations where no single node can be allowed to become a communications chokepoint. Adversaries now target fibre, radio relays and even commercial SATCOM ground stations in the opening hours of a conflict, deliberately collapsing the backhaul layer to blind command echelons. A sovereign mesh-backhaul constellation routes data between ground terminals via inter-satellite links and multiple spot beams, so that the failure or jamming of any one path triggers automatic re-routing through surviving nodes without operator intervention.

The satellite stack fuses Ka-band or V-band inter-satellite crosslinks with UHF or L-band downlinks engineered for low-probability-of-intercept waveforms. Each spacecraft carries an onboard software-defined router that can reprioritise traffic—voice, video, sensor feeds, logistics data—according to mission profiles pushed from a national network operations centre. The constellation is designed for full orbital diversity: no two adjacent satellites share the same ground-track timing, so a localised ground-based directed-energy or kinetic threat cannot silence more than one node simultaneously.

The operational outcome is a self-healing wide-area network that delivers sustained throughput of tens of megabits per second to battalion-level terminals even when terrestrial infrastructure is entirely absent. Commanders retain situational awareness and command authority across dispersed elements, logistics convoys maintain real-time telemetry, and joint fires coordination continues without reliance on any single link. That continuity of command is what separates a force that can adapt from one that freezes under the first electronic blow.

What matters

Backhaul, not access: this layer connects nodes to nodes, not users to the internet—latency and jitter budgets must be set for machine-to-machine synchronisation, not web browsing.
Inter-satellite crosslinks are the load-bearing element; without them, a LEO constellation is a collection of bent pipes that all fail independently when ground stations are denied.
Waveform sovereignty is non-negotiable: a rented commercial backbone operates on published waveforms that adversary electronic warfare units have already characterised.
Orbital diversity is the kinetic resilience argument: a 36-satellite walker at two inclinations loses fewer than three nodes to any single ground-based anti-satellite engagement geometry.

Sovereignty score: 9/10 — A nation that cannot independently route its own battlefield data traffic has surrendered command continuity to whatever commercial or allied provider holds the backhaul keys.

Geopolitical leverage: commercial SATCOM operators are subject to shareholder pressure, export licences and host-nation legal orders that can compel service suspension at precisely the moment military demand peaks—Viasat's Tooway outage at the start of the 2022 Ukraine war demonstrated this exposure in real time.
Waveform and encryption control: sovereign ownership allows classified anti-jam waveforms and NATO-grade or national Type-1 encryption to be integrated at the physical layer, an impossibility on any shared commercial payload.
Supply-chain and ITAR exposure: US-origin crosslink hardware and modems are subject to ITAR/EAR controls; a nation dependent on rented US commercial backhaul can have that service withheld or degraded by US government direction without recourse.
Escalation management: the ability to throttle, reroute or deliberately deny backhaul to specific nodes—including allied nodes—is a sovereign prerogative that cannot be exercised when the infrastructure is rented from a third-party operator.

Reference architecture

Payload: Ka-band inter-satellite crosslinks (26 GHz uplink / 23.5 GHz downlink), 1 Gbps per crosslink; UHF downlink (300–400 MHz) for terminal access in anti-jam LPI mode; software-defined router with onboard traffic prioritisation and autonomous re-routing; optional V-band (60 GHz) optical crosslink variant for high-throughput nodes
Bus class: ESPA-class microsat, 150–200 kg wet mass, 600 W payload power, deployable solar panels, 3-axis stabilised with electric propulsion for station-keeping and collision avoidance
Orbit: LEO dual-shell walker constellation: 24 satellites at 550 km / 53° inclination plus 12 satellites at 1,000 km / 70° inclination for polar coverage; combined revisit ensures at least two satellites in mutual crosslink range over any tactical area of interest at all times
Ground segment: Hardened national network operations centre with buried fibre and diesel-backed UPS; 4 geographically dispersed ground stations (Ka-band TT&C, S-band telemetry backup); mobile tactical gateway terminals (flyaway, vehicle-mounted) as secondary uplink nodes; SatNOGS-compatible amateur-band beacon for health monitoring in extremis
