RF sensing, inside Sensors & instruments: quantum magnetometers and gravimeters, distributed fibre-optic sensing, machine-learning calibration of sensor networks, environmental DNA autosamplers and more. Every item is traced to its specification, from IAGA observatory practice (reference) to IEC 61757 series (fibre optic sensors), and runs on the open Observatory Protocol. [Plan with us](https://observatory.global/contact/) Architecture [The protocol](https://observatory.global/protocol/specification/) **Technologies**: 9 **At the frontier**: 6 **Protocol functions**: 3 of 8 **Industries served**: 21 Reference design, drawn to scale · drag to turn · hover a part **01** What it is ## Frontier and research. Instruments placed in the air, water, ground and spectrum, from weather stations to seismometers, radars and cameras, with the calibration, metadata and quality control that make their readings evidence. Each technology below carries what it is, what we do with it, and the standard it is drawn against. **Frontier** · In situ sensors and instruments ### Quantum magnetometers and gravimeters Atomic sensors with higher sensitivity and less drift for geophysics and navigation backup. We integrate. IAGA observatory practice (reference) **Frontier** · In situ sensors and instruments ### Distributed fibre-optic sensing Acoustic, temperature and strain sensing along existing fibre for seismic, slope and pipeline monitoring. We design, integrate and deploy. IEC 61757 series (fibre optic sensors) **Frontier** · In situ sensors and instruments ### Machine-learning calibration of sensor networks Correcting low-cost sensors against reference sites with models whose drift is monitored. We design, integrate and operate. CEN/TS 17660-1:2021 **Frontier** · In situ sensors and instruments ### Environmental DNA autosamplers Unattended water sampling for biodiversity and pathogen detection. We integrate.

IAEA cosmic-ray neutron sensing guidance **Frontier** · In situ sensors and instruments ### Smart instruments with onboard diagnostics Instruments that report their own health, calibration state and identity to the network. We design and integrate. OGC SensorML 2.1 · IEEE 1451 (smart transducer interface) In situ sensors and instruments ### Air temperature and humidity Ventilated, shielded thermometers and hygrometers sited and exposed to WMO practice. We design, integrate, deploy, operate, maintain and support. WMO-No. 8 Volume I (temperature, humidity) In situ sensors and instruments ### Atmospheric pressure Barometers for weather, altimetry correction and storm surge analysis. We design, integrate, deploy, operate, maintain and support. WMO-No. 8 Volume I (atmospheric pressure) In situ sensors and instruments ### Surface wind Cup, vane and ultrasonic anemometers at standard heights with exposure corrections. We design, integrate, deploy, operate, maintain and support. WMO-No. 8 Volume I (surface wind) **02** Architecture ## Where it sits, and what it speaks. RF sensing draws on 1 domain and 8 layers of the spectrum; the highlighted layers carry this area. It speaks 3 of the protocol's 8 core functions. Meteorology (WMO No. 8 classes) 10 Air quality and atmospheric composition 7 Hydrology and water 7 Ocean and coastal 7 Seismic, geodetic, geomagnetic and radiation 8 RF, acoustics, cameras and radar 9 Calibration, metadata and quality control 7 Frontier and research 6 01**Join** Identity, attestation quote, signed policy. 02**Admit** Admitted for a stated scope, nothing wider. 03**Describe** What, where, how and by whom, with calibration. 04**Time** One clock across the grid, with its error bound. 05**Observe** Every value with quality and provenance. 06**Qualify** Tested against the specification, state on record. 07**Federate** Signed exchange across grids and trust domains. 08**Orchestrate** Software and configuration by signed plan. **03** On the grid ## Every site joins one observing grid. The open networks on the grid today, over real relief and the geodesic cells we count them into, filtered to the space domain this area serves. A site built here enrols into the same grid. **04** In the field ## Where this runs, sector by sector. 6 deployment scenarios from the sector research that rely on rf sensing.
