ZX 18 (ChinaSat 18)

ZX 18 [CAST]

ZX 18 (Zhongxing 18, ChinaSat 18) is a Chinese communications satellite based upon a DFH-4E bus.

The Chinasat 18 provides Ku commercial communications services with 30 Ku-band transponders, Ka broadband communication services with 14 Ka-band MSS spot user beams and exploring Ka-band broadcasting services with 2 Ka BSS-band transponders within the service coverage areas.

The satellite is being manufactured by CAST and will be launched onboard a CZ-3B/G2 launch vehicle. The satellite is to be launched and to provide services in the first quarter of 2019 but delayed to Augus 2019.

The satellite was successfully launched into geostationary transfer orbit, but suffered anomalies after launch. A month after launch, it still remained in geostationary transfer orbit, suggesting a mission failure.
