--- title: "Digital twins and simulation platform | Nexus Observatory" description: "Site twins measured in 3D, network twins that predict coverage, power and timing, Earth twins on real elevation and live observations…" url: https://observatory.global/digital-twins/ publisher: Nexus Observatory Inc. updated: 2026-10-29 --- Nexus Observatory / **Digital twins and simulation** # Model the site before you build it. Site twins measured in 3D, network twins that predict coverage, power and timing, Earth twins on real elevation and live observations, and scenario simulation that tests a plan against flood, heat, load and failure before a contract is signed. [Plan with us](https://observatory.global/contact/) Reference architecture [The open protocol](https://observatory.global/protocol/) **Areas**: 5 **Technologies**: 197 **At the frontier**: 28 **Industries served**: 9 In the field ## River basin Water-level gauges along a real valley floor, a weather station and an edge node: the red isoline is the ground that lies within a few metres of the lowest point of the reach.

Marked: the functions this platform leans on hardest. The protocol itself is open and stewarded by the Nexus Consortium, so what you build here runs anywhere the protocol runs. 01 JOIN 02 ADMIT 03 DESCRIBE 04 TIME 05 OBSERVE 06 QUALIFY 07 FEDERATE 08 ORCHESTRATE **03** · Open and enterprise ## Open by default. Enterprise by contract. The open layer lives on the main site, free to use and build on. Enterprise services are delivered under contract by Nexus Observatory Inc. Open, on the main site - Simulation methods with worked examples - Open terrain and grid layers Enterprise, on this site - Drone survey and 3D site twins - Network planning studies - Scenario studies **04** · Industries served ## 9 industries build on digital twins and simulation. Each industry has its own site: its use cases, its community and the enterprise path, with this platform among the systems behind it.
