NANJING -- China's spacecraft tracking ship Yuanwang 3 wrapped up its mission of monitoring the 46th satellite of the Beidou Navigation Satellite System 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.
