Welcome to TRANTOR!

Check the objectives of TRANTOR

Adoption of 5G Advanced and pre-6G NTN by satellite operators

Accelerate the innovation in 5G satellite networks and ground equipment (user terminals and gateway infrastructure) and ultimately help operators provide better connectivity for communities around the world.

Provide novel satellite components for 5G Advanced NTN

TRANTOR evolved NMS (eNMS) will be delivered with radically new features that are not available in current NMS, nor their roadmaps.

Development of 5G Advanced NTN user equipment and gNB

Physical and link layer aspects are required to be developed so as and advanced antenna aperture with multi-beam, multi-band and multiorbital capabilities and an efficient beam management interface between them.

Development of AI governance modules for resource management

Design and validation of AI-assisted modules for QOS, traffic and radio resource management across the heterogeneous multi-band, multiorbital, multi-satellite network.

Creation of mission planner for the design of future satellite networks

The mission planner will develop scalable optimization techniques for resource allocation withing the considered fleet.

Secure satellite operator network

Research and development of a network Security keeper with a Threat Risk Assessor, Trust Access Unit for static risk mitigation and Security Operation Center.

How does TRANTOR contribute to welfare?

TRANTOR aims at increasing the impact of R+D+i projects on European citizen’s welfare.

TRANTOR proposal has been built around the specific objective of performing an in-orbit demonstration of end-to-end 5G NR satellite communication with advanced multi-band, multi-satellite and multiorbital capabilities and a flexible and secure data driven management across the multiple satellite systems available. But there’s more to discover!


TRANTOR pivots on a set of demonstrations with real infrastructure and scenarios. Here we push innovative concepts from TRL 3 to TRL 6!

End-to-End single band connectivity with a single drone-emulated LEO satellite

This scenario is similar to baseline demonstration, but with an emulated LEO satellite instead of GEO.

Date: June 2024

Multi-band transmission from a single GEO satellite

This scenario is an extended multiend case, where the UE has Advanced capabilities to receive in multiple bands, specifically Ku and Ka.

Date: December 2025

Multiorbital, multi-band transmission using a GEO and a drone-emulated LEO satellite

This scenario puts together all previous scenarios considering a multi-band transmission from a LEO and a GEO satellite.

Date: December 2025

End-to-End single band connectivity with a single GEO satellite

Baseline scenario demonstrating the basic support to end-to-end 5G NR connectivity over a GEO satellite.

Date: June 2024

End-to-End single band connectivity with CU/DU split with OBP satellite

This scenario is similar to baseline demonstration but exploiting on-board processing capabilities for CU/DU splitting.

Date: December 2024

Multi-satellite, multi-band transmission using two GEO satellites

This demonstration extends the previous scenario by considering that the two bands are transmitted from different GEO satellites, thus the UE-A has Advanced multi-satellite (i.e., multiTRP capabilities).

Date: December 2025
