TL;DR: The experimental results agree well with the theoretical predictions, the receiver will improve the flexibility of the intersatellite links without increasing the cost, and the dynamic range of the APD receiver is effectively improved.

TL;DR: In this article, an atmospheric turbulence suppression algorithm based on avalanche photodiode adaptive gain control (APDAGC) for the laser transmission terminal was proposed to suppress atmospheric turbulence in free space optical (FSO) link.

TL;DR: To the best of the knowledge, the first FSO transmission of 5G base station signals between airship platforms with a rate of 2.5 Gbps and a distance of 12 km was realized, and channel turbulence jitter was recorded for laser links of different altitudes, which provides technical and data support for the application of wireless laser links in 5G floating base stations.

TL;DR: High precision in a pseudo-range measurements is achieved, which is the foundation of the inter-satellite laser link, and the framework of the pseudo-code ranging system is introduced.

TL;DR: In this paper, a blimp-borne laser communication terminal was applied to space dynamic base stations to meet the demand for bi-directional transmission of 5G signal laser carriers in space between airships, which achieved an overall technical index of capture probability is better than 98%, the average capture time is 5s, the tracking accuracy was better than 6−15 μrad, the communication rate is 2.5 Gbps and BER is 1E-7.
