'''SEVSAT''' is an acronym for '''S'''hip '''E'''quip [[VSAT]], a maritime satellite broadband system from the Ship Equip Group<ref>{{Cite web |title=Ship Equip Introduces SEVSAT Compact |url=https://maritime-executive.com/article/ship-equip-introduces-sevsattm-compact |access-date=2024-09-12 |website=The Maritime Executive |language=en}}</ref> with its head office in Norway.<ref>{{Cite web |date=2011-01-26 |title=SEVSAT for Entire Varada Marine OSV Fleet |url=https://www.marinelink.com/news/sevsat-entire-varada336925 |access-date=2024-09-12 |website=MarineLink |language=en}}</ref> Ship Equip is a subsidiary of Inmarsat, a mobile satellite services operator.
== History ==
SEVSAT was developed from 2000–2003, and was initially based on [[space segment]] allocations from [[Eutelsat]] and [[Stratos Global Corporation|Stratos]] who had implemented the {{Proper name|iDirect}} technology on some of their satellites. In 2004, Stratos closed down their maritime broadband division, and Ship Equip turned to the start-up space segment broker New Wave Broadband and satellite operator [[Intelsat]]. These two companies had independently decided to implement {{Proper name|iDirect}} technology on the [[Intelsat 907|907 satellite]] that covered central and northern Europe, where customers of Ship Equip were primarily located.
From 2004–2006, while focusing primarily on its local markets in the offshore oil, gas and fisheries segments, the number of SEVSAT customers increased rapidly to over 100 installed systems early in 2006, and 200 systems by mid-2007.{{citation needed|date=July 2017}} The rate of growth during this period caught the attention of the media and in April 2006, the leading financial newspaper in Norway, ''[[Dagens Næringsliv]]'', ran an article indicating that Ship Equip was challenging [[Telenor]], which at that time was the market leader in maritime VSAT.<ref>"Preparing to compete Telenor at sea". ''Dagens Næringsliv'', 10 April 2006, page 14</ref> (Shortly after, Telenor Satellite Services was purchased and merged with France Telecom Mobile Satellite Communications (FTMSC) under the [[Vizada]] brand).<ref>{{cite web|url=http://www.allbusiness.com/media-telecommunications/telecommunications/5252234-1.html/ |title=Apax Partners Acquires Telenor Satellite Services and Integrates the Company into Vizada |date=6 September 2007 | archiveurl=https://web.archive.org/web/20080213060005/https://www.allbusiness.com/media-telecommunications/telecommunications/5252234-1.html |archivedate=13 February 2008 |accessdate=7 July 2017}}</ref> The article initiated further press coverage from regional newspaper [[Sunnmørsposten]] and national newspaper [[Finansavisen]].{{citation needed|date=July 2017}}
In 2009, the Comsys group's annual VSAT report quoted Ship Equip as having a 14.3% share in the maritime [[VSAT]] market.<ref>{{cite web |title=The Comsys VSAT report, 10th edition |page=73 |url=http://www.comsys.co.uk:80/vsat_rep.htm |archiveurl=https://web.archive.org/web/20091208190846/http://www.comsys.co.uk/vsat_rep.htm |archivedate=8 December 2009 |accessdate=7 July 2017 |url-status=dead }}</ref> In 2011, Ship Equip was purchased by London-based [[Inmarsat]] for $159.5 million.<ref name=deselding2011>{{cite web|last1=de Selding|first1=Peter B.|title=Inmarsat Acquires Maritime VSAT Provider Ship Equip - SpaceNews.com|url=http://spacenews.com/inmarsat-acquires-maritime-vsat-provider-ship-equip/|website=SpaceNews.com|accessdate=7 July 2017|date=31 March 2011}}</ref> According to Inmarsat, at the time of purchase, approximately 10% of vessels using Ku-band VSAT worldwide were using networks provided by Ship Equip.<ref name=deselding2011 />
== Technology ==
SEVSAT includes above deck equipment (ADE) and below deck equipment (BDE). The ADE consists of the antenna which, except for some early deliveries, are SeaTel antennas. Two types of SEVSAT systems exist, [[C band (IEEE)|C-band]] and [[Ku band|Ku-band]], denoting the frequency range in which they are capable of receiving a satellite signal. The C-band antennas are generally large, from {{convert|2.4|–|3.6|m|ft|abbr=on}} in dish diameter. The Ku-band antennas are smaller, from {{convert|1|–|1.5|m|ft|abbr=on}} in dish diameter. The BDE most commonly consists of one electronic rack containing the following components: an {{Proper name|iDirect}} [[modem]], the SEVSAT [[Satellite navigation|global satellite]] switching unit, a [[Digital-to-analog converter|DAC]], [[Cisco routers|Cisco Routers]], telephone adapters and a UPS{{Clarify|reason=What is UPS?|date=July 2017}}.
