    China launches new BeiDou navigation satellite
    Source: Xinhua| 2019-05-18 01:12:54|Editor: Mu Xuequan

    XICHANG, May 17 (Xinhua) -- China sent a new satellite of the BeiDou Navigation Satellite System (BDS) into space from the Xichang Satellite Launch Center in Sichuan Province at 11:48 p.m. Friday.

    Launched on a Long March-3C carrier rocket, it is the fourth BDS-2 backup satellite and the 45th satellite of the BDS satellite family.

    After being sent to the geostationary earth orbit and in-orbit tests, it will be connected to the BDS to provide users with more reliable services and enhance the stability of the constellation.

    The BDS-2 system has provided stable and reliable service since it went into operation, and its positioning accuracy has improved from 10 meters to six meters.

    The BDS-2 system and BDS-3 system will jointly provide services before October 2020, and after that the BDS-3 system will be the main force.

    China began to construct its BDS navigation system, named after the Chinese term for the Big Dipper constellation, in the 1990s. It started serving China with its BDS-1 system in 2000 and started serving the Asia-Pacific region with its BDS-2 system in 2012. China will complete the BDS global network by 2020.

    The launch was the 304th flight mission for the Long March series of carrier rockets.

    That video does not tell anything even if it is contrail of the launcher.

    The first and second stages worked as expected, while the third stage malfunctioned. The second stage would be burnt out and separated somewhere east of Taiwan over East China sea. Here is a launch sequence of an earlier LM-4. The right most yellow point is the separation of 2nd stage when the malfunction of 3rd stage happened.

    Nobody fisherman in the area can see or film the failure using a consumer camera or mobile phone except the official tracking ship.

    no, at the separation of 2nd stage, the remaining 3rd stage and the payload would have already left the atmosphere in high velocity, they will burn to almost nothing during re-entry.

    Now I realize that you may refer to sabotage prior or during the launch. Although nothing can be said for certain, I highly doubt. Prior has to be done by someone inside, at the 2nd stage separation outside of atmosphere can only be done by a mid-course interceptor, you know who is the only other country can do that, and that is nothing can be hidden, and it is an act of war. That is almost impossible in peace time.

    I am not suggesting a country sent a mid-course interceptor, of course NOT. What I meant whether there would be a possibility of sabotage during the preparation or even let's say somebody put low standard parts (intentionally or not realizing) on the rockets ... by highly complex and super advanced intelligence operation

    CZ-11/LM-11 solid-fuel rocket. Images are high-resolution. The first sea launch is apparently imminent, with the launch platform on its way to the designated area in the Bohai sea.
