Zusammenfassung:	The invention provides a Beidou synchronous orbit satellite signal Doppler estimation method under a high dynamic condition. The Beidou synchronous orbit satellite signal Doppler estimation method comprises the following steps: initializing Beidou synchronous orbit satellite signal Doppler estimation; estimating the speed of the flight carrier on the vector of the sight direction of the two visible satellites; estimating the velocity vector of the flight carrier; estimating the speed of the flight carrier on the vector of the sight direction of the Beidou synchronous orbit satellite; and estimating Doppler frequency shift of the Beidou synchronous orbit satellite. The method can assist a satellite navigation receiver on a high-dynamic flight carrier to work, and can assist the satellite navigation receiver to work when satellites in the antenna of the satellite navigation receiver are reduced due to attitude change of the flight carrier, and even the satellite navigation receiver loses the positioning resolvi
