'''PSLV-C46''' was a mission of the Indian [[Polar Satellite Launch Vehicle]] (PSLV) rocket, launched on Thursday, May 22, 2019, at 05:30 Hrs (IST) by the [[Indian Space Research Organisation]] (ISRO) from the [[Satish Dhawan Space Centre First Launch Pad|first launch pad]] of the [[Satish Dhawan Space Centre]] at [[Sriharikota]], [[Andhra Pradesh]]. In this mission, the 'Core-Alone' configuration of PSLV was flown (without the use of solid strap-on motors).

The mission launched [[RISAT-2B]] into a [[Geocentric orbit|Geocentric]] [[Sun-synchronous orbit]]. The satellite is an Indian [[Radar imaging|radar]] [[reconnaissance satellite]] that is part of India's [[RISAT]] programme and is the third satellite in the series. The satellite was injected into an orbit of 555 km, 15 minutes and 30 seconds after lift-off, at an inclination of 37 degree to the equator.

==Launch==

The mission was the 72nd launch mission from [[Satish Dhawan Space Centre]], 36th from the [[Satish Dhawan Space Centre First Launch Pad|first launch pad]] and the 48th flight of [[PSLV]]. It was also the 14th flight of the `Core alone' configuration of PSLV.<ref>{{cite web|url= https://www.isro.gov.in/mission_PSLV_C46.html|title=PSLV-C 46 curtain raiser |website=isro.gov.in|accessdate=28 September 2023}}</ref>
The PS-1 stage burned for around 105 seconds and at 52 km. Followed by the ignition of the second stage. The Heat shield was separated at 176 seconds followed by the separation of Second stage at 260 seconds. The PS-3 was ignited at 261 seconds and separated at 561 seconds. This was followed by a successful insertion of the satellite into orbit.

ISRO Chairman [[Kailasavadivoo Sivan|K. Sivan]] congratulated the launch vehicle and satellite teams involved in the mission. With this launch, PSLV has carried 50 tonnes to space by launching 354 satellites, including national, student and foreign satellites.
Almost 5000 visitors viewed the launch from the then recently opened visitors gallery.

==Payload==

The mission carried [[RISAT-2B]] into orbit. RISAT-2B is an advanced [[Earth Observation satellite]] which has a 3.6m radial rib antenna. It also carried two piggyback payloads of Vikram processor and low cost MEMS based [[Inertial Navigation System]] developed by [[Semi-Conductor Laboratory]], [[Chandigarh]] and ISRO [[Inertial Systems Unit]], [[Thiruvananthapuram]] respectively. The Vikram 1601 processor Vikram 1601 was used for first time in navigation computer in the next mission [[PSLV-C47]] <ref>{{cite web|url=https://theprint.in/india/isro-cartosat-most-complex-advanced-indian-satellite/326972/|title=Why ISRO's Cartosat-3 is most complex and advanced satellite India has built|first=Sandhya|last=Ramesh|date=2019-11-27|website=theprint.in|access-date=2019-11-28}}</ref> after being test flown in redundant configuration<ref>{{cite web|url=https://www.isro.gov.in/update/22-may-2019/pslv-c46-successfully-launches-risat-2b|title=PSLV-C46 successfully launches RISAT-2B|publisher=ISRO|website=isro.gov.in|access-date=2019-11-28|archive-date=28 May 2019|archive-url=https://web.archive.org/web/20190528045558/https://www.isro.gov.in/update/22-may-2019/pslv-c46-successfully-launches-risat-2b|url-status=dead}}</ref> on PSLV C46 mission.<ref>{{cite web|url=https://www.isro.gov.in/launcher/pslv-c47-cartosat-3-mission|title=PSLV-C47 / Cartosat-3 Mission|publisher=ISRO|website=isro.gov.in|access-date=2019-11-18|archive-date=28 November 2019|archive-url=https://web.archive.org/web/20191128074359/https://www.isro.gov.in/launcher/pslv-c47-cartosat-3-mission|url-status=dead}}</ref><ref>{{cite web|url=https://www.isro.gov.in/update/21-nov-2019/launch-of-pslv-c47-carrying-cartosat-3-scheduled-november-25-2019-0928-hrs |title=The launch of PSLV-C27 delayed|publisher=ISRO|access-date=21 November 2019}}</ref><ref>{{cite web|url=https://www.isro.gov.in/update/27-nov-2019/press-release-pslv-c47-successfully-launches-cartosat-3-and-13-commercial|title=Press Release - PSLV-C47 successfully launches Cartosat-3 and 13 Commercial nanosatellites into Sun Synchronous Polar Orbit|publisher=ISRO|website=isro.gov.in|access-date=2019-11-28}}</ref>
