NAVRAIL: Satellite‑Based Locomotive Tracking & Communication Terminal

Two‑way satellite communication and real‑time tracking solution for locomotives and railway operations

NAVRAIL is a two way mobile satellite service (MSS) terminal designed for real time tracking and communication of locomotives. Operating on ISRO’s GSAT satellite, it enables continuous transmission of location data and supports two way messaging and emergency communication.

Integrated with GPS and S Band modem technology, the solution ensures accurate tracking and reliable connectivity. Powered by indigenous Software Defined Radio (SDR) chipsets, NAVRAIL enhances operational efficiency, improves train movement management and enables timely passenger information updates.

Open-Integrated DU/CU:

Our DU/CU solution is based on our unique Software Defined Radio (SDR) architecture which provides customers an open and dynamic vRAN platform that not only provides functional flexibility but also optimizes the TCO. This platform is the result of deep expertise in designing DSP based RAN platform. The open fronthaul interface, Control & Management Software is designed as per ORAN standard providing plug and play interoperability with 3rd party Distributed Units (DUs).

5G RU:

This is an ORAN based 5G NR Radio Unit. The solution includes support for various bands specially the low and mid bands like Band 71, 29 and 40. It can be customized for other bands as well.
The solution incorporates a unique front haul compression technique to reduce op-ex for operators
