For FY2016, the company saw a 4.3% upward rise in revenue, with US$1.329 billion coming in, as compared to US$1.274 billion in the previous full year.
The company said it recorded EBITDA of US$794.8 million for the year, an increase of 9.5% over the US$675.4 million in 2015. The latter figure does not include earnings from its deal with Ligado Networks.
Inmarsat said strong results in the government and aviation sectors were offset to some extent by the showing in the maritime and enterprise sectors.
An additional agreement had been signed with Satlink in the first quarter of 2017 for 1500 vessels.
Inmarsat said it expected to service more than 950 aircraft under signed contracts, with another 3000 in the pipeline.
The European Aviation Network was continuing to be developed and an S-band satellite was to be launched in the second quarter of 2017 and the complementary ground component would be offered as a commercial service in the second half of the current year.
Inmarsat chief executive Rupert Pearce commented: "Despite a challenging operating environment in our markets, we delivered a robust performance in 2016, supported by the
first material revenues from our GX platform and a successfully negotiated upgrade of the Ligado agreement."
The agreement in question means Ligado will make aggregate payments of approximately US$108 million, US$111 million and US$118 million to Inmarsat for 2016, 2017 and 2018 respectively, payable in quarterly instalments.
Pearce added: "As a result, Inmarsat remains well-positioned to take advantage of a number of significant growth opportunities in the coming years, supported by our unique skills and experience in global, mobile, broadband services, our solutions-based offerings, our strong global networks and our market-leading distribution channels.
