Navrail

Two-Way Mobile Satellite Service Terminal

Navrail is a Two-way Mobile Satellite Service terminal designed for real-time tracking of locomotives. It has GPS modules and S-Band Modem for transmission of geo-location coordinates and other data to remote hub using ISRO’s GSAT Satellite. The solution enables real-time tracking of locomotives (trains), supports two-way messaging and emergency communication.

The solution aids and assist in better management of train movements, enhances operational efficiency and notify delays and estimated time of arrival to passengers.

The solution is designed to inter-operate with Tejas’ Hub baseband and currently operationalized on ISRO Satellite.

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
