Real-Time Tracking of Starlink Signals:
Advancing Next-Generation Positioning
\n<\/strong><\/span><\/h2>\n<\/div>\n

<\/h2>\n

Introduction<\/h3>\n

At ENC 2026, a joint research team from the University of the Bundeswehr Munich and NOFFZ Technologies presented a breakthrough in real-time processing of non-terrestrial signals: the tracking of Starlink OFDM signals across multiple channels using a high-performance SDR setup. This work demonstrates how commercial LEO constellations like Starlink can be leveraged as signals of opportunity for positioning, navigation, and timing (PNT) applications. <\/p>\n

 <\/p>\n

Pushing the Limits of Real-Time Signal Processing<\/strong><\/h3>\n

Tracking Starlink signals in real time introduces several technical challenges, including extremely wide bandwidths, sparse synchronization signals, and high data throughput requirements. To address these challenges, the team implemented a scalable architecture based on the MuSNAT SDR framework, GPU-accelerated correlation, and a high-performance frontend developed by NOFFZ Technologies. <\/p>\n

The system is built around a synchronized multi-channel RF architecture using two USRP 2955 devices, enabling up to eight RF channels. A LabVIEW-based frontend developed by NOFFZ ensures flexible signal acquisition, efficient buffering, and reliable high-throughput data streaming. <\/p>\n

Real-Time Processing: Performance and Bottlenecks<\/strong><\/h3>\n

The analysis showed that real-time SDR processing is primarily memory-bound rather than CPU-bound. GPU acceleration enables efficient signal correlation, but a block-processing discriminator currently represents the main performance bottleneck. <\/p>\n

Extended observation runs confirmed stable signal tracking across multiple Starlink channels, with signal quality levels consistently above 40 dB-Hz. This demonstrates reliable operation and validates the overall system design. <\/p>\n

Multi-Channel Starlink Observation<\/strong><\/h3>\n

In post-processing mode, the system successfully evaluated multiple RF channels simultaneously, detecting active Starlink signals and handling large datasets efficiently. This confirms scalability for advanced testing scenarios. <\/p>\n

Future work will focus on optimizing algorithms for full real-time capability, improving long-term stability, and extending support for additional RF channels. The system is also being evaluated as a reference solution for advanced positioning applications. <\/p>\n

NOFFZ Contribution<\/strong><\/h3>\n

NOFFZ Technologies contributed by developing the LabVIEW-based frontend software and supporting the hardware integration, enabling reliable high-throughput signal acquisition and processing.<\/p>\n

Real-time tracking of Starlink signals is now a practical solution for next-generation positioning. This work highlights the potential of combining SDR systems with optimized software to unlock new capabilities in hybrid PNT architectures. <\/p>\n
