1.1 Introduction

Space Applications Centre (SAC) located in Ahmedabad, is one of the major centers of Indian Space Research Organization (ISRO), Department of Space, Government of India.

The next-generation Ku/Ka High Throughput Satellite (HTS) GSAT-19 has been launchedfor meeting the country-wide demand for satellite based broadband applications.

The ground infrastructure for complete GSAT-19 system will include two Ka-band Gateways (or Hubs) at Ahmedabad and Bengaluru. Multiple services/Service providers will share the satellite bandwidth at L-band interface in the gateway stations and provide services to the end users.

This “Request for Proposal” is for “Supply, Installation and Maintenance of the complete GSAT-19 Gateway Hub baseband system for Ahmedabad and network of RUTs” and related equipment, defined in this document.

1.2 GSAT-19 Ground Network

GSAT-19 Satellite will provide Ku-band user spot beams, covering Indian mainland as well as islands regions. The Satellite will also provide Ka-band spot beams for Gateways. Figure-1 shows the overall ground system comprising of two Ka-band Gateway earth stations.

The GSAT-19 Ground network will consist of following major components:

1. 8 Ku-band spot beams over Indian region

2. 2 Ka-band spot beams over Indian region with frequency and polarization reuse

3. Two interconnected Ka-band Gateways (Main Gateways) using OFC link/Data connectivity.

4. Ku-band 1.2m VSATs (Remote User Terminals-RUTs)

1.3 Network features

1. The Gateways will communicate to Satellite in Ka-band

2. RUTs will communicate in Ku-band with Satellite.

3

3. Star connectivity between Ku-band RUTs through Ka-band Gateways. The user-to-

user communication will only be possible via Gateways

4. Gateway will be connected to the RUTs through four Ku-band spot beams.

5. Hub transmit and receive simultaneously in both polarizations (Two beams in one polarization, total four beams)
