Receiver-Side Physics-Informed Residual Digital Twin for Predictive Fine Tracking in Inter-Satellite Optical Links

US & West ·

Fine tracking in inter-satellite optical links must compensate residual line-of-sight (LOS) motion despite sensor noise, vibration, model mismatch, and actuator latency. This paper develops a receiver-side physics-informed residual digital twin (PIR-Twin) that combines a nominal LOS transition…

Physics-Informed Neural Networks for Climate-Aware Digital Twins

This study evaluates a physics-informed neural network for potential-temperature forecasting under incomplete thermal observations, constrained by a pressure-coordinate advection-source equation and a diabatic-source closure frozen after the preceding 12 hours. Validation uses hourly ERA5 reanalysis at three pressure levels for one-, two- and three-hour horizons against persistence, local-trend, and two neural baselines.

Digital Twin Enhanced Channel Twin for AI-Native CSI Inference

To reduce computational costs of obtaining channel state information in 5G NR networks, three approaches are studied within a calibrated 3D digital twin: generalizing the channel twin, enhancing performance with a neural receiver, and a data-driven interpolation framework for scalability. The goal is to meet strict microsecond latency budgets of OFDM symbols.
