One star Chinese successful launch of pulsar test satellite k9084

One star: Chinese successful launch of pulsar test satellite data figure: China solid fuel rocket Long March 11 CCTV news, today (November 10th) 7:42, China’s Jiuquan satellite launch center in the long march eleven rocket successfully launched the pulsar test satellite. It is mainly used to verify the performance and space environment adaptability of pulsar detector, and to accumulate the test data in orbit. Pulsar is known as the lighthouse in the universe, they are clear, easy to identify, the location of the universe is more accurate. According to Chinese Aerospace Science and Technology Corporation, micro-blog reported that the pulsar test satellite belongs to sun synchronous orbit satellite, satellite into orbit, will be carried out on orbit test technology, verification of spaceborne pulsar detector performance and environmental adaptability, accumulation in orbit pulsar data, lays the foundation for pulsar detection and verification technology system. The launch is also equipped with 4 micro nano satellite. "One star" refresh the record of China’s solid rocket launch multi satellite. The long march eleven rocket is the only solid rocket in the new generation of launch vehicle in china. This is the first time after its first flight in September 2015, the second launch mission. The launch of the pulsar test satellite and eleven rocket were developed by China Aerospace Science and Technology Corporation five and one for. This is the 239th flight of the long march series launch vehicle. What is a pulsar? Pulsar is actually a kind of remains of the dead star. Its density is very high, the quality of the pulsar per cubic centimeter of up to 10 tons, while it is at high speed rotation, can rotate thousands of times per second. Great quality and high speed, ensure the pulsar have periodic extremely stable, stable ratio of hydrogen atomic clock in the world the most stable and high ten thousand times, known as "the most stable nature of the astronomical clock". Because the United States GPS, China Beidou satellite navigation system accuracy, largely depends on the navigation satellite carrying atomic clock time stability, if we can rely on a very stable signal for pulse X ray pulsar issued its own, for near earth and deep space exploration and interstellar spacecraft provide high accuracy position velocity and time independent navigation information service, will be able to achieve a long time high precision spacecraft autonomous navigation and precision control. The launch of the pulsar test satellite is the world’s first. This time China no longer follow the footsteps of the United States and Europe, becoming the first person to eat crab".
