The 17,000t Yuanwang 3 is the second-generation space tracking ship launched in 1994. It is the most advanced and capable space tracking ship among the Yuanwang fleet. The ship is equipped with an S-band high-accuracy tracking radar as well as sophisticated computer and communications systems to help calculate the re-entry orbit for the spacecraft. During the ShenZhou flight mission, the ship is normally positioned in the South Atlantic off the West African coast. The ship is responsible for the control of the separation of the orbital module and the re-entry module, and the retrofire of the re-entry module at the end of the flight mission. By 2005, the ship had covered a total distance 214,000 nautical miles in 18 missions.

中国排水量17,000吨的远望（Yuanwang） 3号是在1994年下水的第二代航天测量船。它是在远望船队之中最先进和性能最好的航天测量船。该船装备一套S-波段高精度跟踪雷达和复杂的计算机和通信系统去帮助计算宇宙飞船的再入轨道。在神舟（ShenZhou）飞行任务期间，该船通常安排在非洲海岸西部南大西洋中。测量船负责控制轨道单元和再入单元分离、并在飞行任务结束的时候对再入单元点火启动。至2005年，测量船在18个任务中覆盖总航程214,000海里。

Mission Equipment

The ships are fitted with C- and S-band monopulse tracking radar, Cinetheodolite laser ranging and tracking system, velocimetry system, and onboard computers to track and control the spacecraft. They use a combination of inertial, satellite, and stellar for accurate navigation and positioning. Communications include HF, ULF, UHF, and SATCOM, in the form of secured telephone, radio, fax and data link. The ships are also equipped with a range of weather forecasting equipments including weather radar, sonde, and weather balloon, meteorological satellite image receiving terminal.

任务设备

测量船配备有C－和 S－波段的单脉冲跟踪雷达，激光测距经纬仪和跟踪系统，测速系统和舰载计算机去跟踪和控制宇宙飞船。它们使用组合惯性，卫星和星形用于精确导航和定位。通信包括HF、ULF、UHF和SATCOM，采用保密电话，无线电，传真和数据链。测量船也装备多种天气预报装置包括天气雷达、探测装置和气象气球，气象卫星图像接收终端机。
