1. Introduction

Indian Regional Navigation Satellite System (IRNSS) is ISRO’s initiative to build an

independent and regional satellite navigation system based on a constellation of GEO

and GSO satellites. IRNSS has three main segments, namely the space segment, the

ground segment and the user segment. The satellites are placed in two different orbital

planes; 4 satellites in the Geo- synchronous orbit (GSO) with an inclination of 29º and 3

satellites in the Geo-synchronous orbit (GSO) with an inclination of 5º. The space

segment is continuously monitored, controlled and managed by the ground segment.

IRNSS satellites broadcast navigation signals in two bands namely L5 (1176.45±12 MHz)

and S (2492.028 ±8.25 MHz) frequencies and enable the users equipped with IRNSS

receivers to fix their position and time very accurately. IRNSS satellites broadcast 2

types of navigation signals namely Standard Positioning Service (SPS) and Restricted

Service (RS) in each band. The SPS is a free service while the RS is an encrypted service.

The IRNSS Receiver acquires signals simultaneously from all the available IRNSS

satellites and computes the time solution accurately and therefore works as a timing

receiver. Also, the receiver disseminates time and frequency information through

various interfaces. IRNSS receiver also generates the navigation and observation data in

RINEX and time offset data in CGGTTS format which will be used for computing time

difference between two locations.

IRNSS Time Transfer/Timing receivers providing accurate time and frequency signals

using navigation signals from IRNSS satellites can be used for a variety of ground

applications like TTC ground stations, satellite control centers etc. The key features of

the Dual Frequency IRNSS Time Transfer/Timing Receivers are as follows:

1.1. The dual frequency IRNSS Time Transfer/Timing Receiver acquires signals

simultaneously from all the available IRNSS satellites and compute the time

solution and disseminates time and frequency information through various

interfaces.

1.2. The dual frequency IRNSS Time Transfer/Timing Receiver is capable of

generating the measurements data in RINEX and time offset data in CGGTTS

format which can be used for computing the time difference between remote

laboratories.

This document is prepared for inviting proposals from the industry for the development

and supply of Dual Frequency IRNSS Time Transfer/Timing Receivers. This document

primarily describes the scope of work, technical specifications, terms and conditions.

The vendors are required to provide their proposals for development and supply of Dual

Frequency IRNSS Time Transfer/Timing Receivers.

3. IRNSS Signals in Space (SIS)

The IRNSS signal (SIS) consists of BPSK modulated signal with designated code for each

satellite on S and L5 frequency. Basic navigation data rate on all signals is 25 bps and

then ½ FEC encoding and interleaving are carried out. For each IRNSS satellite, separate

codes are specified for SPS data channel. Each IRNSS satellite will transmit downlink

signals consisting of BPSK on L5 & S band carriers by all IRNSS satellites. The details of

power sharing among different components of IRNSS signal will be available in IRNSS

ICD, which shall be provided to the selected vendor at the time of signing contract.
