China's Shenzhou XIV space mission crew landed at the Dongfeng Landing Site on Dec 4. The RUV-900 car-borne phased array satellite communication device developed by Hefei technology company Rhosoon was used by China Media Group during the live broadcast of the astronauts' journey home.

Rhosoon is based in the Hefei high-tech zone in Hefei city, the provincial capital of Anhui in East China.

Featuring a long transmission distance, wide bandwidth and strong mobility, the device guaranteed the uninterrupted transmission of real-time HD video images and voice signals.

What's more, it was the first time the Dongfeng Landing Site experienced crew's return amid cold temperatures at night, with the mercury dropping as low as minus 15 degrees Celsius on the landing day.

The RUV-900 has excellent environmental adaptability, meaning it can support work in environments ranging from 65 C to minus 40 C , ensuring the smooth progress of the live broadcast.

Since its launch in April 2021, the product has served customers in various industries. In September 2021, it realized uplink and downlink rates of 150Mbps/220Mbps at 100 km/h with the cooperation of APT Mobile Satcom Ltd, which set a new record for in-car mobile satellite communication in China.
