The Chinese secret satellite appears in a sudden orbit after the fading law for 6 days

Nearly a week after launch, the area tracking systems managed to locate a mysterious satellite parked in an unusually low orbit. China has launched the experimental satellite to test new technologies, but it is still not clear exactly what it does in its unique tendency.

SHIYAN-28B 01 was launched on July 3 of the Satellite Xichang Launch Center, and riding on a long missile on March 4. The satellite is part of the China’s experimental Xian series, It is said Designed to explore the space environment and test new technologies. It usually takes a day or two for space tracking systems to locate an orbit location, but it was difficult to find the recently launched Chinese satellite.

The U.S. space awareness unit in the United States finally managed to index 28 by 01 on July 9, six days after its launch. The American space monitoring system is located on the Chinese satellite in the orbit of 492 by 494 miles (794 in the orbit books At X. At the time of launch, it is estimated that the satellite will tend to a 35 -degree inclination for the equator in the Earth. However, its unusually low inclination indicates that the missile performs a Dogeg maneuver, which means that it is not the direction in the middle of the road by ascending, and the performance of its second phase is three burns to reduce the inclination, according to McDoel.

It is not clear why China has changed the rocket track after launch or purpose of the low satellite mile. China has not used such a low -woven orbit before, according to SpaceNews. Based on its orbital inclination, the satellite will pass through parts of the South China Sea and the Indian Ocean, and it can be used in regional monitoring or communications tests.

China experiences new satellite technology. Two Chinese satellites recently He conducted a fusion maneuver for tropical fuelThat has the ability to extend the life of spacecraft in orbit. The country generally maintains the details of its experimental tasks under the winding, and the implementation of secret maneuvers in orbit, where the United States tracking systems is its best to monitor.
