Abstract
A method is provided for transmitting a signal by a transmitter device to a satellite moving in orbit around the Earth, the transmitter device and the satellite including wireless telecommunication means.The method includes receiving, by the transmitter device, a signal transmitted by the satellite, termed the presence signal, analyzing a frequency shift induced by the Doppler effect on the presence signal received by the transmitter device, estimating a later change over time of the frequency shift starting from a later predetermined time of the beginning of transmission of the signal to be transmitted by the transmitter device and over a predetermined duration of the signal to be transmitted, and precompensating the later change over time estimated from the frequency shift on the signal to be transmitted.
