Comprehensive ability and level of China space survey ship

"Roy" is the name of China Aerospace Ocean TT&C fleet. At present, there are six ocean TT&C ships in China, named Wangyuan No.1 to Wangyuan No.6 respectively. Roy survey ship is a modern survey ship successfully developed in China in 1970s. Wangyuan No.1 was built in August 1977, and Wangyuan No.2 was built in September 1978. The captain190m, width 22.6m, height 38.6m and displacement 21000t. The survey ship "Roy" is equipped with perfect navigation equipment and accurate measurement system. Roy 1 Wangyuan-1 is China's first generation comprehensive space TT&C ship. It mainly undertakes the whole flight test and measurement and control tasks of satellites, spacecraft and rocket aircraft. Roy 1 was built and launched in Jiangnan Shipyard on August 3 1 day, with a total length of 19 1 m, a width of 22.6 m, a height of 38 m, an average draft of 7.5 m and a full load of 2 1 157 tons. The army was formally established in 1978. In the past 25 years, the ship has made 30 voyages to the Western Ocean, with a total voyage of more than 208,000 nautical miles, accumulated flight time 17376. 1 hour, and total days at sea 1 166 days. Roy-2 is the first generation comprehensive space ocean-going TT&C ship in China. Captain192m, width 22.6m, height 38.5m, full load displacement 210000t, maximum speed 20 knots, endurance100t. Roy II was built in 1978. In the past 20 years, it has made 25 voyages to the Western Ocean, with a total voyage of over 300,000 nautical miles, and accumulated offshore operation time 1826 days. "Wangyuan III" is China's second-generation comprehensive space TT&C ship, which mainly undertakes the maritime monitoring and control tasks of satellites, spaceships and other spacecraft during the whole flight test. The whole ship has concentrated the essence of science and technology in 1990s, as well as the advanced technologies in shipbuilding, machinery, electronics, meteorology, communication and computer in China, and its hardware facilities have reached the international advanced level. Captain Roy No.3 180m, with a width of 22.2m, a maximum height of 37.8m, a full displacement of17,000t, a draught of 8m, a cruising speed of18 knots, a maximum speed of 20 knots and a cruising capacity of18,000 nautical miles. Roy No.4 and Roy No.4 are TT&C space ocean-going ships modified from the original "Xiang Yanghong 10" in August 1998. It is mainly responsible for tracking, telemetry, communication and control of maritime satellites and spacecraft. Captain156.2m, ship width 20.6m, maximum height 39m, full displacement12,700t, draught 7.5m ... The cruising speed of the ship 18 knots, maximum speed 20 knots, self-sustaining power at sea 100 days, endurance/. The hull is reinforced by Class B ice zone, and any cabin damaged will not sink. In just four years, I have made six voyages to the Pacific Ocean and four voyages to the Indian Ocean, and accumulated 8723 hours of offshore operations. On September 29th, 2007, Roy No.5 survey vessel "Roy No.5" was officially delivered to China Satellite Maritime Monitoring and Control Department at Jiangnan Shipyard. Wangyuan No.5 survey ship integrates the latest technologies in shipbuilding, navigation meteorology, electronics, machinery, optics, communication, computer and other fields. It consists of general ship platform and TT&C equipment in space, and is divided into four systems: ship, TT&C, communication and meteorology. The full-load displacement is 25,000 tons, and the wind resistance can reach more than 12. It can sail in any sea area within 60 degrees north and south latitude. Roy No.6 Roy No.6 survey ship integrates the latest technologies in shipbuilding, navigation meteorology, electronics, machinery, optics, communication, computer and other fields. It consists of general ship platform and TT&C equipment in space, and is divided into four systems: ship, TT&C, communication and meteorology. The full-load displacement is 25,000 tons, and the wind resistance can reach more than 12. It can sail in any sea area within 60 degrees north and south latitude. The ship is equipped with large-scale measurement and control equipment such as S-band unified measurement and control system, C-band unified measurement and control system and C-band pulse radar.
