--- title: "Engineering: Design and integration | Nexus Observatory" description: "Engineering, inside Design and integration: lightning protection, grounding and earthing, antenna-supporting structures, foundations and anchors and more." url: https://observatory.global/integration/engineering/ publisher: Nexus Observatory Inc. updated: 2026-11-07 --- Engineering: the mast foundation and loads checked before steel goes up. The loop, step by step: 1. Mast, dish and borehole on a site plan. 2. Sensor, link, edge and console stand ready. 3. Loads and foundations are checked for the mast. 4. Time and place are fixed to every sample. 5. The edge verifies every signature first. 6. Cable routes and earthing are drawn. 7. Only a confirmed result leaves the edge. 8. Interfaces between parts are specified. 9. The relay forwards sealed packets untouched. 10. Dish aim is set to a tenth degree. 11. Sensors check that the response worked. 12. The drawing set passes review. 13. The alert arrives with its evidence attached. 14. The whole chain is archived for audit. 15. Everything settles back to idle. 01 / 15 Mast, dish and borehole on a site plan [Nexus Observatory](https://observatory.global/) / [Design and integration](https://observatory.global/integration/) / **Engineering** # Design packs, bills of materials and drawings. Engineering, inside Design and integration: lightning protection, grounding and earthing, antenna-supporting structures, foundations and anchors and more. Every item is traced to its specification, from IEC 62305-1 to -4 to NFPA 780, and runs on the open Observatory Protocol.

Evidence Traced to its specifications We trace each part of engineering to its specification: IEC 62305-1 to -4, NFPA 780 and IEC 62381. We keep the versions, configurations and test results of engineering as signed records, so a buyer or an auditor can check what was delivered against what was specified. StandardsIEC 62305-1 to -4 · NFPA 780 · IEC 62381 · IEEE 1100 8. Operations Every node watched, every incident closed The operations console shows every node of a network for engineering with its state, its plan and its evidence. An alert arrives with its data and a runbook, acknowledging it opens a work order, and an incident for engineering closes only when the operator records the cause and verifies the fix. 9. Field service One crew, from survey to repair One crew surveys, installs, commissions, calibrates and repairs the sites for engineering, working from each site’s own record. Each visit updates that record, so the next crew knows what is on a site for engineering, when it was last checked and why it changed, and plans spares from that history. 10. Updates Updates in rings, with rollback Software and configuration reach a fleet for engineering in rings: one canary site first, then a few, then all, each ring gated on health and data completeness. A failed gate stops the wave, and each node for engineering returns to its last good release without a site visit. 11. How it scales One base unit, repeated A network for engineering starts with one base node and the instruments it reads. A station adds power and radio, a site adds a relay and a fleet repeats the proven site, so capacity for engineering grows by adding units, never by replacing what works. 12. What you get Programmes, integration and management The reference architecture and interface contracts are open. National observing network programmes, systems integration and programme management are contracted. Pricing follows the programme's scale and phases, with one point of accountability from design to acceptance; the documentation, models and records stay yours at the end.

Next step Engineering, planned with you Tell us the sites, the systems engineering must work with and the outcome you need, with a map or a list of addresses if you have one. An engineer replies with a survey proposal, a design and a scope for engineering, and the plan grows from one site to the network you need.
