Description:

EUTELSAT 172B is a communications satellite featuring a C-band, a Ku-band and a high throughput payload and all electric orbital raising. It will deliver increased capacity for fast-growing applications that include in-flight and maritime connectivity, cellular backhaul, corporate networks, video and government services.

Mission details:

On Jun 1, 2017 Ariane 5 vehicle 590 (flight VA237) placed Viasat-2 and Eutelsat 172B in geotransfer orbit. Eutelsat 172B is the first Airbus/Toulouse Eurostar 3000e satellite, using electric propulsion for orbit raising. It carries 600 kg of xenon, saving 2500 kg of mass compared to the earlier bipropellant chemical-propulsion model.
