'''HySIS''' ([[Hyperspectral imaging|Hyperspectral Imaging]] Satellite) is an [[Earth observation satellite]] which will provide hyperspectral imaging services to India for a range of applications in agriculture, forestry and in the assessment of geography such as coastal zones and inland waterways<ref name=":0">{{Cite web|url=https://www.isac.gov.in/publications/upagrah/pdf/Upagrah-July-Sept2018.pdf|title=Upagrah July–September 2018|date=9 November 2018|website=ISAC.gov.in|archive-url=https://web.archive.org/web/20181109130116/https://www.isac.gov.in/publications/upagrah/pdf/Upagrah-July-Sept2018.pdf|archive-date=9 November 2018|access-date=9 November 2018}}</ref><ref name=":1">{{Cite web|url=https://www.isro.gov.in/isro-develops-optical-imaging-detector-array-hyperspectral-imaging-applications|title=ISRO Develops Optical Imaging Detector Array for Hyperspectral Imaging Applications – ISRO|website=www.isro.gov.in|language=en|access-date=10 November 2018|archive-date=11 November 2018|archive-url=https://web.archive.org/web/20181111133608/https://www.isro.gov.in/isro-develops-optical-imaging-detector-array-hyperspectral-imaging-applications|url-status=dead}}</ref> The data will also be accessible to India's defence forces.<ref name=":2">{{Cite news|url=https://timesofindia.indiatimes.com/india/isro-to-launch-hyperspectral-imaging-sat-with-30-foreign-satellites-on-nov-29/articleshow/66801810.cms|title=Isro to launch hyperspectral imaging sat with 30 foreign satellites on Nov 29 - Times of India|work=The Times of India|access-date=2018-11-25}}</ref><ref>{{Cite news|url=https://theprint.in/science/the-militaristic-claims-of-isros-latest-satellite-have-been-greatly-exaggerated/158545/|title=The militaristic claims of ISRO's latest satellite have been greatly exaggerated|date=4 December 2018|work=ThePrint|access-date=4 December 2018}}</ref>

Before HySIS, other Indian hyperspectral imaging payloads were HySI (Hyper Spectral Imager) on IMS-1 and [[Chandrayaan-1]] and LiVHySI (Limb Viewing Hyper Spectral Imager) on [[YouthSat]].<ref>{{Cite web|url=https://vedas.sac.gov.in/vedas/downloads/ertd/Hyper/L_2_Hyper_Spectral_Sensors_for_Airborne_and_Satellite_Based_Imaging_Moumita_Dutta.pdf|title=Hyperspectral remote sensing and {{sic|it|'s|nolink=y}} potential|last=Dutta|first=Moumita|date=27 August 2018|website=SAC.gov.in|archive-url=https://web.archive.org/web/20190103094846/https://vedas.sac.gov.in/vedas/downloads/ertd/Hyper/L_2_Hyper_Spectral_Sensors_for_Airborne_and_Satellite_Based_Imaging_Moumita_Dutta.pdf|archive-date=3 January 2019|access-date=3 January 2019}}</ref>

==Payloads==
HySIS carries two payloads, the first is the [[VNIR|Visible Near Infrared (VNIR)]] with spectral range of 0.4 to 0.95 micrometres with 60 contiguous spectral bands and the second is the Shortwave Infrared Range (SWIR) with spectral range of 0.85 to 2.4 [[micrometre]]s with a 10 [[nanometre]] bandwidth and 256 contiguous spectral bands. The satellite will have a spatial resolution of 30 metres and a swath of 30 km from its 630 km [[Sun-synchronous orbit]]. [[Space Applications Centre]] and [[Semi-Conductor Laboratory]] were responsible for the development and fabrication of the '[[Charge-coupled device#Frame transfer CCD|Frame Transfer CCD]]' for the VNIR imaging payload while [[ISRO Satellite Centre]] supplied the modified [[Indian Mini Satellite bus|IMS-2 bus]] and carried out the final assembly, integration and testing.<ref name=":0" /><ref name=":1" /><ref>{{Cite news|url=https://www.thehindu.com/sci-tech/science/isro-to-develop-full-fledged-earth-observation-satellite/article19458651.ece|title=ISRO to develop full-fledged hyperspectral imaging satellite|last=D.s|first=Madhumathi|date=9 August 2017|work=The Hindu|access-date=11 November 2018|language=en-IN|issn=0971-751X}}</ref><ref>{{Cite news|url=https://www.deccanchronicle.com/nation/current-affairs/241118/nellore-hyperspectral-imaging-satellite-to-be-launched-on-november-29.html|title=Nellore: Hyperspectral Imaging Satellite to be launched on November 29|date=2018-11-24|work=Deccan Chronicle|access-date=2018-11-26|language=en}}</ref>

==Launch==
[[PSLV-C43]] carrying HySIS and 30 secondary payloads was launched at 04:27:30 UTC, 29 November 2018 from [[Satish Dhawan Space Centre First Launch Pad|First Launch Pad]] of [[Satish Dhawan Space Centre]]. After a flight that lasted 17 minutes and 19 seconds, HySIS was successfully placed in a planned Sun-synchronous polar orbit at around 645 km.<ref name=":2" /><ref>{{Cite web|url=https://www.isro.gov.in/update/29-nov-2018/pslv-c43-successfully-launches-hysis-and-30-customer-satellites|title=PSLV-C43 successfully launches HysIS and 30 customer satellites - ISRO|website=www.isro.gov.in|language=en|access-date=2018-11-29|archive-date=30 November 2018|archive-url=https://web.archive.org/web/20181130030359/https://www.isro.gov.in/update/29-nov-2018/pslv-c43-successfully-launches-hysis-and-30-customer-satellites|url-status=dead}}</ref><ref>{{Cite news|url=https://timesofindia.indiatimes.com/city/kochi/isro-lines-up-3-rocket-launches-in-two-months/articleshow/66538316.cms|title=Isro lines up 3 rocket launches in two months – Times of India|work=The Times of India|access-date=11 November 2018}}</ref><ref>{{Cite web|url=http://ftp.andhrabhoomi.net/content/nlr-2145|title=29న పీఎస్‌ఎల్‌వీ-సీ 43 రాకెట్ ప్రయోగం {{!}} Andhrabhoomi – Telugu News Paper Portal {{!}} Daily Newspaper in Telugu {{!}} Telugu News Headlines {{!}} Andhrabhoomi|website=ftp.andhrabhoomi.net|language=en|access-date=18 November 2018}}</ref>
