Australia is known to be the most arid continent on Earth. Given the link between aridity and the lack of clouds, Australia should be well-placed to have favourable conditions for space-related optical communications. There are many investigations in the literature that focus on identification of the preferred site(s) in those countries for locating satellite-to-ground optical communications infrastructure. On this matter, there are several observations about Australia that are of relevance. Firstly, the country is large and very geologically old and has been subjected over time to significant erosion. Apart from the high terrain in the SE of the continent, the country is relatively flat, which implies the selection of sites with low atmospheric scintillation may be a limiting factor. Changes in cloud cover due to climate change appears to be regional but variable on the decadal scale. Finally, much of the continental interior is inhospitable rangeland and desert with low population density and consequently little in the way of high bandwidth communications infrastructure. We reported previously on an analysis of a 40-year data set of satellite-derived cloud cover statistics to assess cloud cover change. In the present study we investigate, using the most recent decade of that data set, the ranking of six widely distributed sites across the Australian continent. Additionally, we explore multi-site selections to provide a statistically-based ranking of combinations of sites: any combination of three sites of the six sites analysed will achieve an average clear-sky probability greater than 0.90 with some combinations as high as 0.98. The large distances between sites (~500 - 2000 km) supports the assumption of statistically independent cloud cover.

Free space optical communication (FSO) overcomes the challenges of traditional RF-communication in space. With its high data-rates, robustness against electromagnetic influences and being free from organizational regulations, FSO provides solutions for high-rated Direct to Earth (DTE) and Intersatellite (ISL) communication. With the raising CubeSat market and the increasing number of satellite constellations, the request for compact and efficient designs increases as well. Thus, German Aerospace Center (DLR) developed the world's smallest laser communication terminal for CubeSats (OSIRIS4CubeSat, O4C). O4C is flying on the CubeL satellite in the PIXL-1 mission. The payload itself has a modular design which allows to transfer the technology into other fields of satellite communication. The basic payload can be adapted and/or extended by different subsystems to provide solutions for intersatellite communication or Quantum Key Distribution (QKD). This paper gives an overview of the first results of the PIXL-1 mission. After the Launch and Early Orbit Phase (LEOP) the first contact between the laser terminal and DLR's Transportable Optical Ground Station (TOGS) could be established. Afterwards, further experiments were done to demonstrate the performance of the O4C terminal. Furthermore, this paper shows the ongoing and upcoming developments. Based in the O4C dedicated terminals towards higher data rates, optical intersatellite links and QKD on CubeSats are and will be developed.

Satellite miniaturization and sinking costs of manu-facturing and launches are bringing Moon missions in the focus of many space companies and agencies. However, achieving the desired data rates on CubeSats over long ranges is proving increasingly challenging with traditional radio-frequency communication systems. Free-space optical (FSO) communications offer a compact, light, and low-power alternative with higher data throughput and fewer limitations (e.g., fewer governmental regulations, channel interference, eavesdropping...). Based on its long heritage of laser communications and new-space tech-nology, the German Aerospace Center (DLR) is investigating SelenIRIS-a miniaturized terminal for Moon-Earth optical data transmissions-for its OSIRIS program. This paper will analyze the necessary adaptations that are required to transfer the technology from the flight-proven low Earth orbit terminals like OSIRIS4CubeSat (O4C) [1] to a concept mission in Lunar orbit.

Satellite based quantum key distribution (QKD) enables the delivery of keys for quantum secure communications over long distances. Maturity of the technology as well as industrial interest keep increasing. So does the technology readiness of satellite free-space optical communications. A satellite QKD system comprises a quantum communication subsystem and a classical communication subsystem (public channel). Both are implemented with free-space optics. Thus, in satellite QKD system design, there are strong synergies that should be exploited as much as possible and lead to an all-optical satellite QKD system. In this paper, we present a system like this locating all optical channels in ITU DWDM C-band. We focus on the overall conceptual design and the setup of the optical channels for quantum and classical signal transmission. The system description addresses the breadboards of a transmitter laser terminal (Alice terminal), a receiver laser terminal, (Bob terminal), the public channel implementation, the interfaced QKD system and the deployed encryption system. The design basis for the Alice terminal is the laser terminal development OSIRISv3. The design basis for the Bob terminal is the ground station development THRUST. The later contains an adaptive optics correction to enable single mode fiber coupling. This enables the interfacing to almost arbitrary quantum receivers such as the Bob modules used in the described experiment. The public channel is composed of a bi-directional 1 Gbps IM/DD system and a MODEM that implements a proprietary waveform optimized for free-space channels. The system was experimentally analyzed in a field test in the framework of the German initiative QuNET which addresses the use case of quantum secure communication for authorities. The results of the experiment are used to model a feasible LEO satellite-ground link. Performance indicators such as quantum bit error rate and secure key rate of a potential mission are estimated analytically.

Photonic components offer an advantage of minimizing the size, weight and power consumption (Swap) of a satellite communication payload. This paper presents how this can be utilized in Increasing the capacity of Very High Throughput Satellites (VHTS) while reducing the cost at the same time. Photonics is capable of offering a limitless bandwidth in THz range at the band around 1550 nm while offering high data rates and frequencies with almost lossless propagation in an optical fibre. However, at present only a few demonstrations of photonic devices in non-critical equipment with limited degree of integration can be found in the satcom industry as we as in literature. With the advancement of the photonic technology, it is now possible to develop Tbps-like software defined photonic payload. PhLEXSAT project, funded under the European Union H2020, is led by DAS Photonics in cooperation with MDA UK, Eutelsat, Axenic, HHI Fraunhofer and Argotech.

Optical feeder links (OFLs) benefit from the vast amount of bandwidth available in the THz-regime of the electro-magnetic spectrum, and could enable future terabit-per-second satellite systems. This study assesses the end-to-end performance of analog coherent OFLs for digital video broadcasting (DVB) applications, employing phase modulation (PM) and double-sideband suppressed carrier (DSB-SC). Though both PM and DSB-SC suffer from non-linear distortion, we show that with DSB-SC the optical modulation index can be reduced such that the modulator is operated in the linear regime, without sacrificing the signal-to-noise ratio (SNR). Using end-to-end simulations of a geostationary orbit (GEO) feeder link the Es/N0 penalty due to the optical feeder link (OFL) is determined. With typical system parameters and link losses the OFL-induced penalty remains below 1 dB, even under moderate turbulence conditions and APSK32 (8/9). As a result, the usual suspects, the RF traveling-wave tube amplifier (TWTA) and the RF user channel, remain the key limiting factors for the end-to-end performance.

With typical system parameters and link losses the OFL-induced penalty remains below 1 dB, even under moderate turbulence conditions and APSK32 (8/9). As a result, the usual suspects, the RF traveling-wave tube amplifier (TWTA) and the RF user channel, remain the key limiting factors for the end-to-end performance.","PeriodicalId":237453,"journal":{"name":"2022 IEEE International Conference on Space Optical Systems and Applications (ICSOS)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121803154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
