Proposed Solution Overview

Technical Architecture

The solution follows a layered architecture that separates hardware abstraction, control logic, network integration, and management functions:

Hardware Abstraction Layer (HAL): Standardized interfaces for all subsystems with well-defined contracts, explicit signatures, data types, FSM definitions, and fault enumerations
Control & Coordination Layer: Link establishment and tracking state machines, adaptive power and gain control loops, atmospheric condition classification, cross-subsystem fault correlation engine
Network Integration Layer: IEEE 802.3 Ethernet bridging, VLAN handling and QoS passthrough, link aggregation (LACP), SNMP/NETCONF management interfaces
Fleet Management Platform: Cloud-based multi-tenant backend, REST API, WebSocket-based real-time telemetry streaming, OTA update distribution with rollback, geographic visualization and alerting
Field Operations Tooling: Mobile coarse alignment application, commissioning self-test sequences, site survey and calibration tools
Verification Infrastructure: Digital twin simulator with physics parameter ingestion, hardware-in-the-loop test harnesses, automated verification suite with requirement traceability

Key Technical Approaches

Beam Steering: Two-stage scanning: coarse wide-angle followed by fine-tracking transition; IMU-based vibration compensation; sub-milliradian positioning through closed-loop control; automatic re-acquisition with event logging.

Link Adaptation: Continuous atmospheric channel assessment; received signal strength and BER monitoring; automatic FEC rate adjustment; hitless switchover to backup link when primary degrades.

Fault Management: Structured fault taxonomy across all subsystems; correlation engine to distinguish root causes from symptoms; self-healing recovery procedures; escalation paths for conditions requiring intervention.

Security Model: Defense-in-depth with authentication, encryption, and access control; certificate-based mutual authentication for fleet management; tamper detection with evidence preservation; audit logging of all management operations.

Digital Twin Approach: Physics-based parameter sets with provenance tracking; version stamping for parameter-hardware compatibility; fidelity gates to ensure simulation accuracy; contract-reality divergence detection during test.
