METHOD FOR TRANSMITTING A SIGNAL BY A TRANSMITTER DEVICE TO A NON-GEOSYNCHRONOUS SATELLITE

摘要

A method 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 the following steps: receiving, by the transmitter device, a signal transmitted by the satellite, referred to as a presence signal, analyzing a frequency shift caused by Doppler effect on a main frequency of the presence signal received by the device, evaluating a proximity criterion between the transmitter device and the satellite on the basis of the analysis of the frequency shift, and transmitting a signal by the transmitter device if the proximity criterion is met.
