A B5G Non-Terrestrial-Network (NTN) and Hybird Constellation Based Data Collection System (DCS)

In beyond 5G (B5G) non-terrestrial network (NTN) systems, satellite technologies play an important role. Especially for data collection systems (DCS), low-earth orbit satellites have many advantages. Such as global coverage, low latency, and high efficiency. As a miniaturization technology, CubeSat has attracted extensive attention from a large number of scholars. Satellite constellations can coordinate for distributed tasks. This paper proposes a B5G NTN-based data collection system. A CubeSat constellation achieves global coverage as the basic space platform for DCS. The 5G terrestrial network is used as the data bearer network of the gateway station. A traffic load balance strategy is proposed to optimize the system's efficiency. As a unified hardware platform, software-defined radio (SDR) is compatible with various sensor data models. Finally, the design was verified by a series of experiments.

Automated summary

This paper proposes a B5G NTN-based data collection system using low-earth orbit satellites as a CubeSat constellation for global coverage and the 5G terrestrial network as the data bearer network. The system also incorporates a traffic load balance strategy for optimization. The design was verified through a series of experiments.
