Positioning system and automatic father satellite setting method thereof

The invention discloses a positioning system and an automatic father satellite setting method thereof, and the method is characterized in that the method comprises the following steps that a first satellite transmits a wireless frame, and a server records all second satellites receiving the wireless frame of the first satellite, and records the second satellites as a second satellite set; the server sends an instruction to measure the distance from the second satellite to the first satellite one by one and records distance measurement information; the second satellites meeting conditions are screened out from a second satellite set according to the distance measurement information, the first satellite is set as a parent satellite of the second satellite meeting the condition; the technicalmeans and combination of inter-satellite wireless frame sending, inter-satellite distance measurement, parent satellite quality evaluation, parent satellite selection algorithm screening and the likeare adopted, so the paren
