NVS-01 is the first in the series of second generation navigation satellite and the ninth satellite in the Navigation with Indian Constellation (NavIC), with an alternate name of, IRNSS-1J. It will augment the existing satellite and bolster the capability of the NavIC constellation by adding more robustness and new features. [3] ISRO already launched IRNSS 1A, 1B, 1C, 1D, 1E, 1F, 1G, 1H and 1I. The satellite is intended to replace IRNSS-1G and augment the constellation of geosynchronous navigation satellites after IRNSS-1I. [4]

Payload

NVS-01 has two types of payloads, navigation payload and the ranging payload. The navigation payload transmits navigation service signals to the users. This payload is operating in L1 band, L5 band and S band. A highly stable Rubidium atomic clock is part of the navigation payload of the satellite. Failure of the imported Rubidium atomic clocks across the fleet of previous generation of satellite led to the creation of an indigenous option. NVS-01 is the first navigation satellite to host the indigenous clock. [5]

The ranging payload consists of transponder which is operated in CDMA mode for two-way range measurements. The IRNSS satellites continuously emits time stamped navigation signals, which are received by the ground-based user receivers. The information is then processed by the receivers to derive their own position, velocity and time. The system provides seamless, uninterrupted services under all weather conditions. [6]

The new generation of navigation satellite features a new and improved encryption system for bolstering the communication of the satellite specially for the restricted users. [7]

Satellite

The satellite will help in maintaining the continuity that was lagging due to the failure of Rubidium Atomic clocks in previous satellites whilst bolstering the feature set with new bands and longer life. The NavIC space segment consists of seven satellites. With the new series of satellites, ISRO aims to tap into the low power satellite navigation segment like Smart Watches and fitness trackers whilst cementing its Navigation system by allowing it to seamlessly integrate and interoperate with the existing Navigation system. The inclusion of the civilian L1 band will further bolsters NavIC position in the mass market. [8]

Launch

NVS-01 was successfully launched by 15th flight of GSLV (GSLV-F12) in Mk2 configuration on 29 May 2023. [9] [10]

<span class="mw-page-title-main">Satellite navigation</span> Use of satellite signals for geo-spatial positioning

A satellite navigation or satnav system is a system that uses satellites to provide autonomous geopositioning. A satellite navigation system with global coverage is termed global navigation satellite system (GNSS). As of 2023, four global systems are operational: the United States's Global Positioning System (GPS), Russia's Global Navigation Satellite System (GLONASS), China's BeiDou Navigation Satellite System, and the European Union's Galileo.

The GPS-aided GEO augmented navigation (GAGAN) is an implementation of a regional satellite-based augmentation system (SBAS) by the Government of India. It is a system to improve the accuracy of a GNSS receiver by providing reference signals. The Airports Authority of India (AAI)'s efforts towards implementation of operational SBAS can be viewed as the first step towards introduction of modern communication, navigation and surveillance / air traffic management system over the Indian airspace.

<span class="mw-page-title-main">GSAT-4</span>

GSAT-4, also known as HealthSat, was an experimental communication and navigation satellite launched in April 2010 by the Indian Space Research Organisation on the maiden flight of the Geosynchronous Satellite Launch Vehicle Mk.II rocket. It failed to reach orbit after the rocket's third stage malfunctioned. The third stage was the first Indian-built cryogenic-fuelled upper stage, and was making its first flight. The ISRO suspects that the failure was caused by the third stage not igniting.

<span class="mw-page-title-main">Indian Regional Navigation Satellite System</span> Satellite navigation system

The Indian Regional Navigation Satellite System (IRNSS), with an operational name of NavIC, is an autonomous regional satellite navigation system that provides accurate real-time positioning and timing services. It covers India and a region extending 1,500 km (930 mi) around it, with plans for further extension. An extended service area lies between the primary service area and a rectangle area enclosed by the 30th parallel south to the 50th parallel north and the 30th meridian east to the 130th meridian east, 1,500–6,000 km (930–3,730 mi) beyond borders where some of the NavIC satellites are visible but the position is not always computable with assured accuracy. The system currently consists of a constellation of eight satellites, with two additional satellites on ground as stand-by.

IRNSS-1A is the first navigational satellite in the Indian Regional Navigation Satellite System (IRNSS) series of satellites been placed in geosynchronous orbit.

GSAT-10 is an Indian communication satellite which was launched by Ariane-5ECA carrier rocket in September 2012. It has 12 KU Band, 12 C Band and 6 lower extended c band transponders, and included a navigation payload to augment GAGAN capacity. Following its launch and on-orbit testing, it was placed in Geosynchronous orbit at 83.0° East, from where it will provide communication services in India.

IRNSS-1B is the second out of seven in the Indian Regional Navigation Satellite System (IRNSS) series of satellites after IRNSS-1A. The IRNSS constellation of satellites is slated to be launched to provide navigational services to the region. It was placed in geosynchronous orbit on 4 April 2014.

IRNSS-1C is the third out of seven in the Indian Regional Navigation Satellite System (IRNSS) series of satellites after IRNSS-1A and IRNSS-1B.
