“…Regarding the modulation and coding, most of the current and planned space missions are designed around simpler schemes such as Phase Shift Keying (PSK) [9]. Space applications often benefit from choosing coding schemes and rates separately for uplink and downlink, and an adaptive coding rate can be useful for changing atmospheric conditions.…”

The prospect of mankind returning to the Moon has garnered a great amount of attention in recent years. Dozens of lunar missions are planned for the coming decade which will require the development of a sustainable communication infrastructure with high data rates and minimal latency. Space communication systems thus far have relied on Radio Frequency (RF) links alone, but recent developments in laser communications have demonstrated that Free Space Optical (FSO) links can achieve much higher data rates. Upon considering the respective benefits and drawbacks of RF and FSO links, we make a case for the integration of these two technologies into a hybrid RF/FSO lunar communications architecture which leverages small satellites in a Low Earth Orbit (LEO) constellation. We include a case study for this technology designed in Analytical Graphics' Systems Tool Kit (STK) software. Results are presented in terms of chain access duration, propagation delay, transmission loss, Signal-to-Noise Ratio (SNR), and Bit Error Rate (BER). This architecture shows potential to revolutionize extraterrestrial communications and pave the way for highly ambitious future missions in space.

These technologies are not mature under space environment (TLR=3), so further investigation and development will be needed.…”

A new era of manned lunar exploration is dawning. Optical communication technology is expected to become indispensable for high-speed data transmission from lunar explorers to the Earth. This paper describes the expectations for contents from the Moon and the estimated amount of information. Then, two types of Lunar-Earth optical communication systems are discussed, including a comparison between direct communication with an optical ground station (OGS) and communication through a data relay satellite in geostationary orbit (GEO) around the Earth.

“…In the future, further developments in the domain of OLEODL are expected in Japan (VSOTA on RISESAT), Europe (OSIRIS-v3 [28], OPTEL-μ [29]) and the United States [30]. Standardisation efforts are ongoing in the Consultative Committee for Space Data Systems (CCSDS) to advance global cooperation in this domain [31].…”

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.
