Abstract: A method for transmitting data from a population of devices to a relay station travelling with respect to one another. For transmitting the data to the relay station, each device includes at least one transmission slot resulting from a channel access method and a transmission window within which the relay station is to travel. The relay station is to broadcast an instruction to the population of devices before the data transmission, and, upon receiving the instruction, at least part of the population of devices is to set a modified transmission slot.

Abstract: A device in a population of devices arranged at a celestial body for transmitting data to a relay station orbiting the celestial body. The relay station and the population of devices are to travel with respect to one another such that the relay station is to receive signals that include the data in data packages from the population of devices. The device includes trajectory data of the relay station, a transmitter to use the trajectory data so as to transmit a signal that is part of the signals, a data processor, and a computer program which, when executing on the data processor, is to calculate a Doppler shift based upon the trajectory data, and modify the signal to thereby compensate for the Doppler shift of the signal that results from the travelling of the relay station and the population of devices with respect to one another.

Abstract: A relay station configured to orbit a celestial body and configured to receive data from a population of devices arranged at the celestial body, the relay station and the devices configured to travel with respect to one another. The relay station includes a receiver configured to receive signals from the devices, the signals including a signal that is part of the signals, the signal including signal data in data packages that are at least part of the data. The relay station also includes a signal-processing device configured to receive the signal from the receiver and extract the signal data from the signal. The signal-processing device is configured to correct the signal for a positive Doppler shift or a negative Doppler shift. The relay station also includes a transmitter configured to transmit the signal data from the signal processing device to a server arranged remotely from the relay station at the celestial body.

Abstract: A method for determining an optimized transmission window having a first start time and a first end time, for transmitting data from a device to a relay station travelling with respect to one another. The optimized transmission window is determined by the device listening during at least part of the travelling. The device determines the optimized transmission window by starting a receiving mode for receiving a signal from the relay station, setting the first start time when receiving the signal, stopping the receiving mode when reception of the signal stops, and setting the first end time.
