According to the Chinese news service Xinhua, a Long March 4c launch which took place from the Jiuquan launch site in China on 1 September (2 September local time) was carrying a scientific satellite payload for land survey work. Western analysts think that the Yaogan 17 payload and two subsatellites carried are actually used for ocean electronic intelligence/surveillance. Lift off took place at 1916 GMT.
