JCSAT-17 is a geostationary communications satellite ordered by SKY Perfect JSAT Group to be designed and manufactured by Lockheed Martin on the A2100 platform with a 15-year design life. Its payload is composed of S-band transponders with a flexible processor that will allow it to redirect capacity to concentrate on disaster relief efforts or other high-volume events.

GEO-KOMPSAT 2B is a South Korean geostationary meteorological satellite developed by KARI. It is one component of the two satellite GEO-KOMPSAT 2 program.

The GEO-KOMPSAT-2 program is to develop two geostationary orbit satellites, the meteorological GEO-KOMPSAT-2A (GK2A) and the ocean monitoring GEO-KOMPSAT-2B (GK2B) sharing the same satellite bus. The lifetime of both satellites will be no less than 10 years.

GEO-KOMPSAT-2B (GK2B) is for the ocean monitoring mission and the environment monitoring mission, featuring the Airbus Space-built GOCI-II(Geostationary Ocean Color Imager-II) and the Ball Aerospace-built GEMS(Environmental monitoring sensor) payloads. The satellite will be stationed at 128° East. GEO-KOMPSAT-2B is planned for launch in 2019. Due to defective parts, the launch was delayed to the 1st quarter of 2020.
