Gogo(s gogo) is gradually adding satellite services in an effort to boost speeds on its highly-congested inflight internet networks. It’s already announced a plan to launch a hybrid ground-to-air and satellite connectivity network this year, but next year it will go all satellite, offering more capacity to its current airline partners as well as support for international flights.

The new service is called 2Ku and it will make use of the extensive network of geo-stationary satellites to beam high-capacity transmissions to planes flying both over land and over the open ocean. At an aviation conference in Europe, Gogo demoed a 70 Mbps downlink connection to an aircraft using a new high-gain antenna design that Gogo CTO Anand Chari said squeezes out twice the performance of any service provided by its in-flight connectivity competitors.
