Aerial photo shows China's spacecraft tracking ship Yuanwang-3 sailing on the southern Pacific Ocean, on June 21, 2019. China's spacecraft tracking ship Yuanwang-3 wrapped up its mission of monitoring the 46th satellite of the BeiDou Navigation Satellite System (BDS) and arrived at a port in east China's Jiangsu Province Monday. The tracking ship has traveled more than 30,000 nautical miles in the one-month monitoring mission. China sent the 46th satellite of the BDS into space from the Xichang Satellite Launch Center in Sichuan Province on June 25 and Yuanwang-3 completed the maritime monitoring mission of the satellite launch from the southern Pacific Ocean. Yuanwang-3, China's second-generation space tracking ship, has completed 83 monitoring missions from the sea, including maritime tracking of the Shenzhou spacecraft, the Chang'e lunar probe and BeiDou satellites.
