Abstract
A method for the transmission to a non-geostationary satellite of data, each device storing data, carried out by each device, includes performing successive Doppler shift estimations including receiving, by the device, a signal from the satellite comprising at least one 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 position of the device relative to the position of the satellite, defining a transmission window during which the position of the device relative to position of the satellite verifies the elevation emission criterion, defining a transmission time included in the transmission window and defined randomly, emitting, at the transmission time, a signal including data stored by the device and the position of the device relative to the position of the satellite.
