“…The CLICK-B/C can support the full-duplex interconnection and a more than 20Mbps communication rate among satellites [22]. In almost the same timestamp, the TBIRD terminal will demonstrate a new 200Gbps downlink with only 18 × 10 × 10cm 3 volume and a less than 2.25kg mass [23].…”

Due to the high directionality and short wavelength of laser transmission in space, satellite laser communication can achieve high speed, wide bandwidth, high precision, and high security with no electromagnetic spectrum constraints. It has become a promising direction to construct the laser space network. Recently, relative products, on-orbit demonstrations, and researches have been conducted on laser space networks. Considering this network as a graph, this paper presents a comprehensive survey from nodes, edges, to architectures of this graph, corresponding to laser communication terminals, laser space links, and laser space network architectures. For each content, current achievements are introduced and future trends are analyzed accordingly. Through this survey paper, we aim to present the prospect to develop laser space networks in the next space generation and provide potential research directions to interested researchers or engineers.

“…The platform vibration is naturally happened at the satellite communication due to the high-speed motion or the influence of the space environment, which causes the capturing error between the two communicating satellites 13 . In addition, vibration will also cause received power fluctuations, thereby reducing the quality of the system 14,15 .…”

Laser intersatellite link (LISL) offers a large bandwidth, low power loss and high reliability transmission scheme to the satellite communication. With the rise of commercial applications of giant constellations, the LISL technology could be used to build the free-space backbone network to deliver the information all over the world. However, the operational scheme on the new frequency-carrier also brings new issues. The transmission performance is highly dependent on the channel quality, i.e., the laser channel for our case. In this paper, we build up the theoretical model of the transmission channel for the LISL system, considering the sun outage, the doppler frequency shift and the platform vibration as the major noise sources for the free-space laser communication system. The numerical simulation is carried out to quantify the detail impacts from these sources and to define the operational region of the QPSK transmission system. According to our calculations, the large elevation angle, the low frequency shift and the less vibration could improve the transmission performance.

“…Pointing, acquisition and tracking (PAT) mechanisms are indispensable in mitigating beam misalignment problems in optical links. PAT mechanisms are generally implemented in two stages; coarse pointing and fine pointing subsystems for keeping the communication link [4][5][6] [7]. Coarse pointing involves pre-aligning the optical heads, utilizing directional (guiding beacons) or positional sensors (GNSS) [8], attitude actuators and sometimes the platform's propulsion systems.…”

Line-of-sight laser communication application scenarios are numerous including land, mobile, maritime, airborne and space platforms for conventional and tactical utilization. However, beam pointing and stabilization are complicated in dynamic systems such as orbiting satellite to ground receiver, drones, aircrafts and metropolitan free-space optical links vulnerable to natural and artificial disturbances. Small Satellite platforms such as CubeSats are even more challenging due to their limited size and on-board resources. This paper presents an experimental study on a feedback photodiode array sensor assisted control of a one-axis micro-electromechanical (MEMS) fine steering mirror stabilizing a laser communication link on an optical bench in the laboratory. Disturbance profiles similar to vibrations on dynamic platforms are induced into the setup using an electrodynamic vibration machine to test the efficacy of the MEMS fine steering control mechanism. The Photodiode Array (PDA) sensor collocated with an Avalanche Photodiode at the receiving section provides sustained information about the transmitter's movements and beam displacements while the received optical signal strength is continuously monitored. The feedback signals are transmitted to the FSM controller via a radio link. We demonstrate the capacity to stabilize a laser beam transmission in the presence of external disturbances and platform movements using a PDA sensor assisted control.
