As Optical Low Earth Orbit Downlinks (OLEODL) serve for sensor data download from earth
observation satellites, their link scenario is strongly asymmetric, since the data flow is mostly …

Low-Earth-orbit (LEO) satellites for Earth observation have typical orbit altitudes of 400 to
600km. Since their on-board sensors resolution is advancing, the need for very high rate …

With the advancement of earth-observation sensor resolution, demand for high data rate
satellite downlinks is increasing. Laser communication is an attractive technology offering …

As telemetry downlink data rates from EO-satellites increase and available radio frequency
transmission spectrum narrows, optical data downlinks based on directed modulated laser …

Optical High-Speed Telemetry Downlinks for high data volumes from Earth Observation
Satellites in Low Earth Orbit (OLEODL) is currently developing into a future standard in high …

The recent developments in the field of direct-to-Earth (DTE) for low-Earth-orbit (LEO)
satellite optical links have shown the potential benefits of on-off-keying-based …

The paper investigates the benefits of employing a Variable Data Rate (VDR) scheme in
optical Low Earth Orbit (LEO) Direct-to-Earth (DTE) links at system level. In contrast to the …

Following the recent publication of the first recommended standard on optical
communications by the Consultative Committee for Space Data Systems (CCSDS), the focus …

The demand for satellite links with ever higher bandwidths continues to grow with the market
of Earth observation services. Free bands in the microwave spectrum are already a highly …

This paper reports on the assessment of the communication performance of DPSK-and OOK-
based free-space optical (FSO) links in satellite-based applications, including LEO …
