On Tuesday, 13 May 2025, TeleOrbit GmbH, Fraunhofer IIS and the Bundeswehr University Munich delivered the final results of the NAVISP EL1-066 project. GOOSE-VTL set out to harden GNSS positioning in dense urban environments by replacing conventional scalar tracking with deeply-coupled vector tracking (VT) and INS-aided deep coupling (DC) inside the GOOSE software-defined receiver.

Key achievements of the project were:

• End-to-end architecture realised
  GOOSE v2 hardware-accelerated SDR hosts new VT and DC tracking loops, a real-time PVT engine, and a multipath/quality monitor (SQM) that flags distorted signals.
• Robust performance proven in simulation
  Spirent-based urban-canyon scenarios showed VT maintaining continuous tracking where scalar loops lost signal lock.
• Field validation of deep coupling
  Ten-minute drive tests on the UniBw Munich campus confirmed that DC-aided GOOSE out-performed standalone GNSS.

GOOSE-VTL demonstrates that deeply-coupled vector tracking in an open SDR platform can deliver the resilience and accuracy that next-generation autonomous systems need in GNSS-challenged urban settings.

This project was funded by NAVISP Element 1 which focuses on technology push in the PNT domain.
