The vehicle was built with the intent of coastal security like [[Naval mine|mine]] counter-measures, coastal monitoring and [[reconnaissance]]. AUV 150 can be used to study aquatic life, for mapping of sea-floor and [[mineral]]s along with monitoring of environmental parameters, such as current, [[temperature]], depth and [[salinity]]. It can also be useful in cable and pipeline surveys.
It is built to operate 150 metres under the sea and have cruising speed of up to four knots.<ref name=auvaco>{{cite web|title=AUV System Spec Sheet|url=http://auvac.org/configurations/view/102|publisher=auvac.org|accessdate=6 February 2013}}</ref><ref name=ndauv>{{cite web|title=AUV-150|url=http://www.navaldrones.com/AUV-150.html|publisher=Naval Drones|accessdate=6 February 2013}}</ref><ref name=mtr>{{cite web|title=Autonomous Underwater Vehicle |url=http://www.technologyreview.in/computing/24488/ |archive-url=https://archive.today/20130412230417/http://www.technologyreview.in/computing/24488/ |url-status=dead |archive-date=12 April 2013 |publisher=MIT Technology Review |accessdate=6 February 2013 }}</ref><ref name=gtau>{{cite web|title=AUV-150 - An indigenous submarine launched |url=http://www.geospatialtoday.com/gst/index.php?option=com_content&view=article&id=490:-auv-150-an-indigenous-submarine-launched-&catid=1:latest-news |publisher=Geospatial Today |accessdate=6 February 2013 |url-status=dead |archiveurl=https://web.archive.org/web/20100228163448/http://www.geospatialtoday.com/gst/index.php?option=com_content&view=article&id=490%3A-auv-150-an-indigenous-submarine-launched-&catid=1%3Alatest-news |archivedate=28 February 2010 }}</ref><ref name=goiit>{{cite web|title=Sea trials of Autonomous Underwater Vehicle to be conducted this month-end|url=http://www.goiit.com/posts/list/news-sea-trials-of-autonomous-underwater-vehicle-to-be-conducted-1065787.htm|publisher=Goiit|accessdate=6 February 2013|archive-url=https://web.archive.org/web/20120307192322/http://www.goiit.com/posts/list/news-sea-trials-of-autonomous-underwater-vehicle-to-be-conducted-1065787.htm|archive-date=7 March 2012|url-status=dead|df=dmy-all}}</ref><ref name=spsn6>{{cite web|title=DRDO ready to demonstrate indigenous AUV |url=http://www.spsnavalforces.net/exclusive/?id=10&h=DRDO-ready-to-demonstrate-indigenous-AUV |archive-url=https://archive.today/20130413205648/http://www.spsnavalforces.net/exclusive/?id=10&h=DRDO-ready-to-demonstrate-indigenous-AUV |url-status=usurped |archive-date=13 April 2013 |publisher=SPS Naval Forces |accessdate=6 February 2013 }}</ref><ref name=kimer>{{cite web|title=AUV (vehículo autónomo submarino)|url=http://kimerius.com/hidrodin%C3%A1mica-18/auv/|publisher=Kimerius|accessdate=6 February 2013|archive-date=4 March 2016|archive-url=https://web.archive.org/web/20160304000425/http://kimerius.com/hidrodin%C3%A1mica-18/auv/|url-status=dead}}</ref><ref name=gizmt>{{cite web|title=India readies Autonomous Underwater Vehicle |url=http://www.gizmowatch.com/entry/amazing-india-readies-autonomous-underwater-vehicle/ |archive-url=https://archive.today/20130411004231/http://www.gizmowatch.com/entry/amazing-india-readies-autonomous-underwater-vehicle/ |url-status=dead |archive-date=11 April 2013 |publisher=Gizmowatch |accessdate=6 February 2013 }}</ref>

==Description==

===Structure===
AUV-150 is cylindrical-shaped with streamlined fairing to reduce [[hydrodynamic drag]]. It is embedded with advanced power, propulsion, navigation, and control systems. The UUV includes a pressurized cabin which is necessary for the diving and flotation system to work properly; this also helps to increase its sealing power against water leakage into the cabin. The AUV 150 weighs 490 kg, is 4.8 metres long and has a diameter of 50 cm.<ref name=th group=News>{{cite news|title=Sea trials of Autonomous Underwater Vehicle scheduled for January-end|url=http://www.hindu.com/2011/01/03/stories/2011010362441400.htm|archive-url=https://web.archive.org/web/20140302230727/http://www.hindu.com/2011/01/03/stories/2011010362441400.htm|url-status=dead|archive-date=2 March 2014|accessdate=6 February 2013|newspaper=[[The Hindu]]|date=3 January 2011}}</ref><ref name=th2j group=News>{{cite news|title=Sea trials of Autonomous Underwater Vehicle to be conducted this month-end|url=http://www.thehindu.com/news/cities/Kochi/article1025416.ece|accessdate=6 February 2013|newspaper=The Hindu|date=2 January 2011}}</ref><ref name=toi6f group=News>{{cite news|title=India-made stealth submarine to be tested next month|url=http://articles.timesofindia.indiatimes.com/2010-02-20/india/28131767_1_cmeri-robotics-auv|archive-url=https://archive.today/20130411042729/http://articles.timesofindia.indiatimes.com/2010-02-20/india/28131767_1_cmeri-robotics-auv|url-status=dead|archive-date=11 April 2013|accessdate=6 February 2013|newspaper=[[The Times of India]]|date=20 February 2010}}</ref><ref name=math group=News>{{cite news|title=ആളില്ലാ അന്തര്‍വാഹിനി ഇടുക്കി ഡാമില്‍ പരീക്ഷിച്ചു |url=http://www.mathrubhumi.com/story.php?id=83854 |accessdate=6 February 2013 |newspaper=Mathrubhumi |date=17 February 2010 |url-status=dead |archiveurl=https://web.archive.org/web/20100428081014/http://www.mathrubhumi.com/story.php?id=83854 |archivedate=28 April 2010 }}</ref>

===Control system===
The AUV is autonomous, that is automatic and self-controlled. It has an onboard computer that can be pre-programmed to dive to preset depths, move along preset trajectories, and return to the base after completing the assigned tasks. A remote control option is provided in order to perform special tasks.

===Propulsion===
It is propelled by water-jet propulsion which comprises thrusters for generating motion in different directions to control surge, sway, heave, pitch, and [[Aircraft principal axes|yaw]], while preventing the vehicle from rolling. Two arrays of cross-fins have also been fixed at the two ends to provide additional stability to the AUV.

===Navigation===
The autonomous vehicle is equipped with a number of navigational equipment to locates its own geographical position Such as inertial navigation system, depth sonar, altimeter, doppler velocity log, global positioning system through ultra-short baseline system and forward looking sonar to facilitate obstacle evasion and safe passage.

===Payload===
It is equipped with an underwater video camera that can send wireless video pictures from underwater to a monitor above water surface along with side scan sonar. The submarine is equipped with CTD or conductivity-temperature-depth recorder and several sensors that can measure orientation, current and speed.

===Communication===
For smooth communication and distant intervention, the vehicle is equipped with hybrid communication system: it uses radio frequency while on surface and acoustic under water.

===Power===
The vehicle uses a Lithium polymer battery and can operate up to depths of 150 metres at speeds of 2-4 knots.

==Test trial==
A full-scale prototype of AUV- 150 was put to sheltered freshwater test in January 2010 under tight security. It was brought in a truck from Durgapur in West Bengal under secrecy inside a container up to Kulamavu reservoir at Idukki in Kerala and the vehicle was later taken to the middle of the reservoir on a boat. The choice fell on Idukki Since Kulamavu has a centre associated with Indian Navy and the reservoir being very deep. The biggest arch dam of Asia, Idukki reservoir is located about 250 km from Kerala's capital Thiruvananthapuram, and its lake covers an area of 60 km<sup>2</sup>. The preliminary test was conducted for seven to eight days and the results was reported to be very satisfactory. The final leg of the still-water trials was conducted in the reservoir between September and October 2010.

==Sea trial==
The first series of sea trials of AUV-150 was commenced from 13 July 2011 off the [[Chennai]] coast. From July 13 to July 16 the diving depth of the AUV-150 was increased in stages, it reached consecutive depths of 35,79m 79.86m and 119.95m and finally on 17 July 2011 Auv-150 reached the specified depth of 150 m. Despite extreme rough sea environments (Sea-state of 4), the sea trial was satisfactory. Although minor problem was faced in recording video frames.
