Back within the 80s, HughesNet was the satellite innovator of VSAT broadband. In days, then-named Hughes Network Systems owned DirecTV and operated substantial geostationary satellites that beamed data down to televisions. Then and now, the corporation also provided to corporations, like transactions on gas pumps. Its first buyer was Walmart, which wanted to staff across the and its house in Bentonville.
Inside the mid-90s, the firm a hybrid world-wide-web method referred to as DirecPC: A user’s computer system submitted a request through dial-up; it was directed to an internet server and completed by means of a satellite, beaming the requested down towards the user’s dish.
In the year 2000, Hughes offering its initial two-way interactive method. But with the service-including the equipment-low sufficient would invest in it was a challenge. To accomplish that, the firm decided it required its satellites, and in 2007, it launched Spaceway. Although nevertheless in use, this satellite was especially vital when it launched, based on Hughes, was the initial to incorporate on-board packet switching. Its VSAT broadband capacity: 10Gbps.
Meanwhile, a business known as Viasat spent a decade in R&D before launching its very first satellite in 2008. Known as ViaSat-1, the satellite incorporated some new , such as spectrum reuse. This allowed the satellite to choose among different bandwidths so it could pump data down to Earth without interference, even when it neighbored the track of another satellite’s beam, and then reuse that spectrum in connections that were not adjacent.
It was also faster and more powerful. When it went up, its 140Gbps capacity was more than all with the other satellites covering the US combined, based on Viasat President Rick Baldridge.
The market for satellites had really been the individuals that had no choice. If you couldn’t get anything else, it was a of last resort. It essentially had a ubiquitous coverage but really, not much data. It had been relegated to things like transactions at gas stations.
Over the years, HughesNet (now owned by EchoStar) and Viasat put up faster and faster GSOs. HughesNet put up EchoStar XVII (120Gbps) in 2012, EchoStar XIX (200Gbps) in 2017, and plans to launch EchoStar XXIV in 2021, which the corporation says will offer 100Mbps to consumers.
ViaSat-2 went up in 2017 and now has a capacity of 260Gbps, and three different ViaSat-3s are planned for 2020 or 2021, each to cover a different part on the globe. ViaSat has said that three ViaSat-3s combined are projected to have a capacity of a terabit per second, double the capacity of all other satellites circling Earth combined.
We have so much capacity in space that it is changing the whole dynamic of delivering this traffic through VSAT broadband. There is no inherent limit in terms of what can be provided.
