Key Points Covers terrestrial satellite infrastructure including stations, gateways, and control sites Works with the space segment to provide end-to-end service Handles control, communications, and service transport between satellites and terrestrial networks Constraints include site availability, telemetry and control coverage,…
Key Points Focuses on recovery and continuity under disruption Applies to technical and operational systems Includes tolerance to faults and disruptions Often paired with redundancy and availability Operates through design features such as redundancy, fault isolation, recovery procedures, and fallback…
Key Points Measures operational availability over time Used in service and infrastructure monitoring Often expressed as a percentage Important in service-level discussions Quantifies how long a service remains available versus down over a reporting period Definition Uptime is the period…
Key Points Represents the in-orbit part of a satellite system Includes satellites and onboard payload functions Works with the ground and user segments Defines the space-based service layer Handles the orbital side of the communication or sensing function Definition Space…
Key Points Uses more than one gateway path or site Improves resilience and service continuity Relevant in satellite and network architectures Reduces single-point gateway dependency Requires path independence and failure domain analysis Definition Gateway Diversity is the use of multiple…
Key Points Describes write throughput capacity of a historian system Must match or exceed sensor, tag, and event volume produced by operational systems Affects visibility freshness, data loss, backlog growth, and storage saturation Constrained by tag count, sample frequency, network…
Key Points Serves multiple users or services simultaneously Shares access capacity across a common terminal Used in access and satellite environments Requires capacity sharing, traffic controls, and access scheduling Lower hardware cost offset by increased contention and traffic management complexity…
Key Points Carries traffic in the forward direction from infrastructure to endpoint Important in satellite and access networks Often called the downlink from network to user perspective Service delivery often depends on robust forward link performance Operates across satellite communications,…
Key Points Stores curated analytical data organized around known schemas Optimized for reporting and query performance Used in business intelligence and enterprise analytics Supports repeatable analytical workloads Requires ETL or ELT processes for data preparation Provides governance and data consistency…
Key Points Stores values with timestamps or ordered time context Supports history, trend analysis, and reporting Common in operational and monitoring systems Organized around time to enable efficient writes and chronological query patterns Used in monitoring systems, industrial historians, observability…
