The '''Liquid Propulsion Systems Centre''' ('''LPSC''') is a [[research and development]] centre functioning under [[ISRO]].<ref>{{Cite web |url=http://www.lpsc.gov.in/ |title=LPSC Webpage |access-date=17 December 2013 |archive-date=17 December 2013 |archive-url=https://web.archive.org/web/20131217121434/http://www.lpsc.gov.in/ |url-status=live }}</ref> It has two units located at Valiamala, in [[Thiruvananthapuram]], [[Kerala]], and [[Bengaluru]], [[Karnataka]]. LPSC is augmented by [[ISRO Propulsion Complex]] at [[Mahendragiri, Tamil Nadu|Mahendragiri]] of [[Tamil Nadu]].

LPSC is engaged in development of liquid and [[Cryogenic#Fuels|cryogenic propulsion]] stages for launch vehicles and auxiliary propulsion systems for both launch vehicles and satellites. Activities related to liquid propulsion stages, cryogenic propulsion stages and control systems for launch vehicles and spacecraft is done at [[Thiruvananthapuram]]. Precision fabrication facilities, development of transducers and integration of satellite propulsion systems are carried out at [[Bangalore]]. The developmental and flight tests along with assembly and integration are done at [[ISRO Propulsion Complex]], [[Mahendragiri, Tamil Nadu|Mahendragiri]] in [[Tamil Nadu]].

The development of liquid propellant stages for the [[PSLV]], control systems for SLV-3, [[ASLV]], [[PSLV]] and [[GSLV]], satellite propulsion systems including those for [[INSAT]] and IRS and production of pressure transducers are done by the LPSC for [[India]]. The LPSC has developed indigenous cryogenic upper stage for [[GSLV|Geosynchronous Satellite Launch Vehicle]] (GSLV) which was successfully test fired by ISRO on 4 August 2007. LPSC is currently developing a restartable [[Liquid oxygen|LOX]]-[[Methane]] engine and stages for the [[Next Generation Launch Vehicle]], which uses a reusable booster stage.<ref>{{Cite web |title=Multiple restarts of Launch Vehicle Stages - ISRO successfully carried out ignition trial using Spark Torch Igniter |url=https://www.isro.gov.in/ISROsuccessfullycarriedoutSparkTorchIgniter.html |access-date=2025-03-08 |website=www.isro.gov.in}}</ref>

LPSC's current director is Dr. [[M. Mohan]].<ref name=Director>{{cite news|title=New Directors at ISRO centres|url=http://www.thehindu.com/news/national/tamil-nadu/new-directors-at-isro-centres/article6167830.ece|access-date=2 July 2014|newspaper=The Hindu|date=2 July 2014|archive-date=21 October 2022|archive-url=https://web.archive.org/web/20221021081857/https://www.thehindu.com/news/national/tamil-nadu/new-directors-at-isro-centres/article6167830.ece|url-status=live}}</ref>

==LPSC Trivandrum==
This unit serves as LPSC headquarters, and is involved in research and development of Earth-storable and cryogenic propulsion for launch vehicles. It delivers engines, stages, associated control systems and components for launch vehicle and spacecraft.
