“…These vectors are being used by various CCSDS affiliated space agencies to simulate their proposed schemes. In addition to the power vectors, the receiver noise model (shot-noise limited, thermal-noise limited, or realistic avalanche photodiodes) is also necessary to be used in the simulations [14]. Also, absolute link budget calculations must provide values of received mean power, which would be dependent on further parameters like elevation, aperture sizes, signal divergence, or atmospheric transmission, etc.…”

“…Since the fluctuation of the acquired signal directly impacts the optimization process of each plane wave, the analysis is performed for values of SNR ≈ [14,40] and received powers of −60 dBm and −36 dBm, respectively. This range of received power is representative for multi-gigabit data reception, either working with direct detection or coherent systems [19,20], and it corresponds for the APD power range between low and high SNR where the noise has minimal impact in the optimization process.…”

In a down-link scenario, performance of laser satellite communications is limited due to atmospheric turbulence, which causes fluctuations in the intensity and the phase of the received signal leading to an increase in bit error probability. In principle, a single-aperture phase-compensated receiver, based on adaptive optics, can overcome atmospheric limitations by adaptive tracking and correction of atmospherically induced aberrations. However, under strong-turbulence situations, the effectiveness of traditional adaptive optics systems is severely compromised. We have developed an alternative intensity-based technique that corrects the wave-front by iteratively updating the phases of individual focal-plane speckles, maximizing the power coupled into a single-mode fiber. Here, we present the proof of concept for this method. We show how this technique improves the quality of the received signal by 4 dB gain with less than 60 power measurements under strong turbulence conditions.

Optical free-space links will shape the high-speed communications technology landscape for space missions substantially in the next years. The dramatically reduced signal spread-as compared to any radio frequency (RF) technology-provides a variety of advantages: increased power efficiency, the avoidance of interference and thus spectrum regulation issues, the inherent tap-and spoof-proofness and, most of all, the vastly increased data rates (DRs) will make this technology a 'game changer' comparable to the introduction of glass fibre instead of copper cables previously used in the global communication infrastructure. As one use case of optical space links high-speed geostationary data-relays for the repatriation of low Earth orbit (LEO) observation satellite telemetry have been tested and are currently implemented operationally by various space agencies [1-4]. Deep space missions will also boost their DRs by several orders of magnitude by sending their data to large optical receiver telescopes, NASA is currently transforming its Deep Space Network to an optical DNS, and we also see European developments in optical deep space communications [5-7]. In order to connect very high-throughput communication satellite systems to the Tbps-regime (Terabit-per-second), optical uplinks can solve the spectrum bottleneck that RF links would otherwise encounter [8]. In the LEO regime (inter-satellite, as well as optical LEO downlinks-OLEODL), distances are way shorter, allowing very high data rates while, at the same time, reducing the requirement for high system sensitivity (where complexity and thus costs generally increase with sensitivity). Instead, components and technologies that are close to commercial-off-the-shelf (COTS) from terrestrial fibre communications can be used, allowing both very high throughputs and moderate-to-low system costs. Using COTS components in inter-satellite as well as downlinks is also supported by the shorter life time of LEO missions, implying less radiation exposure of these components. In the last years, several demonstrations of OLEODL have been performed by various agencies [9-15], and its commercialisation will be seen in near future.
