The company says that it has seen month over month voice growth of 68-92 per cent in Q2 2012, processing over 67,000 pre-paid voice minutes and transferring 4GB of data (saving 14GB through optimisation) in June.
The company estimates that it saved its maritime users more than 75 per cent on the standard cost of this traffic over Inmarsat terminals.
"Horizon’s substantial growth validates it has gained visibility with crew in the maritime industry and that they recognise the value that Horizon offers," said Sandy Johnson, COO, SatCom Global.
"Through the affordability that Horizon’s optimisation provides crew members have also been able to increase their time spent online by 59 per cent."
Horizon offers a VoIP platform using the company’s SmartPacket technology, which allows for voice communications at speeds of 2 kbps.
In addition to VoIP, Horizon also includes a range of optimised data applications including compressed e-mail, accelerated web browsing and instant messaging.
As such, the company says that the system can reduce crew communications costs by consuming as much as 80 per cent less data than other VoIP services and saving upwards of 20kB per website viewed.
