摘要: A method of estimating Doppler shift for air to ground communications comprises obtaining an initial position aircraft during flight, wherein the includes onboard database with stored positions a plurality station towers; when subsequent nears closest tower, requesting estimation tower; current estimation; defining vector from position; tower subtracting determine vector; differentiating respect time velocity magnitude and calculating shift.
