Turn back the clock to about 1999 and you’ll get a sense of what internet service is like for most vessels at sea in 2021. 如果他们幸运的话, 他们的下载速度是2到5mbps, and the few that get more have a large monthly bill — some subject to wild fluctuations due to overages.
There’s typically a competition for bandwidth between ship operations, 船员, 客人或承包商, and any type of monitoring of the cargo or the ship’s systems. Forget about your crew being able to video-chat with their family when you’re using all the bandwidth to download a chart or send data back to the land office. Even when the business side of things is quiet, there’s often not enough for several crew members to stream video simultaneously. Everyone is competing for access to a small internet pipe.
It’s a simple case of demand outstripping supply. The move to VSAT has improved on the lower-frequency L-band satellite that’s been an important maritime connectivity tool for decades, but the traditional VSAT services fall far short of meeting the data demands of today’s world. All of us want lightning-fast internet everywhere we go, but the systems in use on most ships today simply can’t meet the need.
As Viasat, we’ve created a Ka-band satellite network that has the capacity to deliver. Our newest satellite — ViaSat-2 — has about 260 Gbps of capacity, 使我们竞争对手的能力相形见绌. It has completely changed the game in commercial aviation, and that high-speed internet experience is now available for the maritime world. Viasat has partnered with Cobham 天线系统 to integrate our technology in a proven and respected antenna platform, in addition to launching a maritime service that delivers a true at-home internet experience at sea.
Viasat通常提供25+ Mbps的速度, 无限数据, a fixed monthly bill and no surprise overages. 有这样的服务, vessel operators can meet the personal connectivity needs of their crew and guests while running more efficient and safer ship operations. Cruise lines and super yachts can allow their guests to use the same applications they would at home to enhance their onboard experience. 就像我们的航空公司客户一样, cruise ships can offer guests an array of features and products, some sponsored by companies who want to reach this large audience.
我们该怎么做呢? Viasat engineers reimagined what a satellite operating in the high-frequency Ka-band could do a decade ago, culminating in the launch of the 140 Gbps ViaSat-1 satellite in 2011. Using dozens of smaller “spot” beams and innovative reuse of the spectrum within each beam, we were able to realize astonishing gains in capacity — quieting many critics who said it couldn’t be done.
这是容量的巨大飞跃, 相对, at a time when many satellites had under 10 Gbps of capacity. ViaSat-2 raised the stakes even more, while adding coverage on both coasts of the U.S. in addition to the Caribbean and the Gulf of 墨西哥. Our KA-SAT satellite covers our clients in Europe.
接下来是ViaSat-3的发射, a three-satellite global constellation that will enable high-speed broadband on vessels almost anywhere on earth. 每颗卫星都是1,000 Gbps (1 terabyte) of capacity and an even more innovative beam structure that will afford tremendous bandwidth flexibility to adjust capacity on the fly.
Global coverage is an essential leap for our 海上 Service, and soon our clients will get a great internet experience wherever they go. 与此同时, we bring this incredible new capability to all who need it in our current coverage area, 无论是渔船还是科考船, 货船货船或油船, 游船:河流或海洋游船, 能源船或游艇. 这在很多方面都是一个巨大的变化, and we’re eager to enhance communications in a way that’s never been done before.
