Beschreibung
Zusammenfassung:	The invention relates to the field of satellite positioning, and discloses a coaxial dual-rotor helicopter positioning system, which comprises a radiation source transmitting module arranged on a helicopter and used for transmitting a helicopter radiation source signal, and two radiation source signal receiving modules respectively arranged on a first Beidou satellite and a second Beidou satellite and used for receiving the helicopter radiation source signal, and the signal receiving antenna is arranged on the ground base station and is used for receiving the radiation source signals processed by the signal processing modules in the first Beidou satellite and the second Beidou satellite. The radiation source transmitting module of the helicopter transmits the radiation source signals to the two Beidou satellites, the two Beidou satellites are used for calculating the time difference and the frequency difference of the received radiation source signals, the ground base station is matched for calculating the pr
