A satellite observation and probabilistic modelling system for calibrated weather-risk estimates.
Atmospheric state estimation depends on the spatial coverage, temporal sampling and uncertainty of the underlying observations. Our research examines how observational constraints propagate through probabilistic models into analysis uncertainty, forecast reliability and hazard estimates.
Meneltir is developing a novel satellite constellation as part of an integrated observation-to-decision architecture. Proprietary atmospheric observations, onboard processing and probabilistic hazard modelling are being designed together. Forecast and decision value will be assessed through simulation, benchmark evaluation and independent validation.
The constellation is being developed to supply proprietary atmospheric observations to a unified processing and modelling pipeline. Observation latency, uncertainty characterisation and information content are treated as joint requirements, connecting orbital system design to downstream analytical performance.
Our architecture connects spacecraft operations, onboard computation, ground processing and model evaluation. The engineering programme addresses power, thermal, bandwidth and reliability constraints alongside data quality, traceability and uncertainty propagation.
Proposed architecture. Payload geometry and orbits illustrative.
Our novel constellation is being designed as a proprietary observation source for atmospheric inference. The processing chain will characterise measurement uncertainty, preserve data lineage and support consistent evaluation across acquisition, processing and modelling stages. Observation quality and downstream information value will be assessed separately.
Selected processing is being designed to run in orbit, supporting quality control, event tagging and prioritised delivery. The architecture retains archival data and store-and-forward capability. Evaluation will measure end-to-end latency, data completeness and computational reliability under realistic operational constraints.
Weather OS is being developed to ingest public and licensed satellite, radar, station and reanalysis data before proprietary observations become available. The planned pipeline combines task-specific adaptation of open-weight forecast models with hazard translation, uncertainty quantification and versioned indices. Intended interfaces include BUFR for observation exchange, Zarr/NetCDF analysis fields and APIs for decision workflows.
Our validation plan combines traceable pre-launch characterisation, independent reference comparisons and end-to-end uncertainty analysis. Observing-system simulation experiments will assess prospective information gain before hardware flies. Subsequent evaluation will test model impact, probabilistic calibration and decision performance against reproducible baselines.
Parametric indices & basis-risk analysis.
Weather OS is being designed for hazard-index construction, backtesting against loss histories and programme monitoring with locked model versions. Traceable inputs and reproducible event reports are intended to support independent calculation-agent verification.
Probabilistic wind & precipitation risk.
The modelling pipeline targets temperature, wind and gust risk, precipitation structure and short-range evolution. Calibrated predictive distributions and uncertainty metadata are intended to support renewable-generation and weather-exposure workflows through APIs.
Hazard thresholds & event provenance.
Proposed products include precipitation, heat and wind-risk indicators for threshold-based monitoring. Versioned processing, observation lineage and quantified uncertainty are designed to make alerts reproducible and suitable for integration with emergency-management systems.
Headquartered in Malta, Meneltir brings together satellite engineering, atmospheric science and research computing. Our technical work spans probabilistic spatio-temporal modelling, uncertainty propagation, distributed data processing and the power, thermal and reliability constraints of computing in orbit.
Current work centres on constellation architecture definition, payload trade studies and the Weather OS modelling pipeline built on public and licensed observations. The research programme evaluates information gain, ensemble-analysis spread, predictive calibration and observation-to-product latency, with reproducible benchmarks linking system performance to downstream decisions.
