Abstract
A method for the transmission to a non-geostationary satellite of data stored by a ground-based device being carried out by the device, includes entering an awaken mode, performing successive Doppler shift estimations: receiving, by the device during the awaken mode, a signal from the satellite including a frequency parameter and an elevation emission criterion, performing a Doppler shift estimation based on the frequency of the received signal; estimating a Doppler rate of frequency change to obtain a relative position of the device, defining a transmission window during which the position of the device relative to position of the satellite verifies the elevation emission criterion, and if the position of the device relative to the position of the satellite verifies the elevation emission criterion: emitting at the frequency parameter a signal including the data stored by the device.
