This review paper analyzes technology trends observed in New Space missions, using a patent analytics approach. The analysis is complemented with a literature review of the subjects identified. The main objective of this review is to draw a comprehensive picture of technology trends in New Space and to discuss potential scenarios for further development of this novel type of missions. Building on the existing scientific literature, we survey alternative definitions and then propose our own definition of New Space missions as synthesis of the ongoing debate in the field.

We identified more than two hundred organizations active in the development of both upstream and downstream products and services for New Space missions. Using a commercially available patent analytics tool, we collected 933 patents protecting technologies disclosed by those organizations. We used the Latent Dirichlet Allocation (LDA), a topic modeling algorithm, to analyze patents' data and to identify the underlying structures in New Space's technology trends. Ten major topics have been identified respectively named “Remote sensing & image acquisition”, “Flying/launch systems”, “Telecommunication systems”, “Constellation management”, “Digital Processing Architectures”, “Image analysis”, “Manufacturing process & materials”, “Feature recognition and extraction”, “Antenna systems”, and “Space platforms”.

A deeper analysis of patents' claims revealed a core cluster defined as “data cluster” including data analysis topics (Remote sensing & image acquisition, Image analysis, and Feature recognition and extraction), data transmission topics (Telecommunication systems and Antenna systems from both hardware and software perspective) and related enabling technologies such as constellation management. Based on this analysis, the evolution of data cluster related technologies is surveyed in order to review the current technology state of the art as well as identifying potential areas that will benefit the most from further technology developments to improve New Space missions’ performance.

Lastly, we identify technology trends for future New Space development based on the insights obtained by the synthesis of our literature and patent survey. We discuss the key directions for future development emerging from our review, such as the use of commercial off the shelf components, the increasing use of miniaturized technology, and software defined technology.

这篇评论论文使用专利分析方法分析了在新太空任务中观察到的技术趋势。该分析辅以对所确定主题的文献综述。本次审查的主要目的是全面了解新空间的技术趋势，并讨论进一步发展这种新型任务的潜在情景。在现有科学文献的基础上，我们调查了替代定义，然后提出了我们自己对新太空任务的定义，作为该领域正在进行的辩论的综合。

我们确定了 200 多个活跃于为新太空任务开发上游和下游产品和服务的组织。使用商用专利分析工具，我们收集了 933 项保护这些组织披露的技术的专利。我们使用了潜在狄利克雷分配 (LDA)，一种主题建模算法，来分析专利数据并确定 New Space 技术趋势中的底层结构。确定了十大主题，分别命名为“遥感与图像采集”、“飞行/发射系统”、“电信系统”、“星座管理”、“数字处理架构”、“图像分析”、“制造工艺与材料” 、“特征识别与提取”、“天线系统”和“空间平台”。

对专利权利要求的更深入分析揭示了一个定义为“数据集群”的核心集群，包括数据分析主题（遥感和图像采集、图像分析和特征识别和提取）、数据传输主题（来自硬件的电信系统和天线系统）和软件视角）和相关的使能技术，例如星座管理。在此分析的基础上，对数据集群相关技术的演变进行了调查，以审查当前的技术状态，并确定将从进一步技术发展中受益最多的潜在领域，以提高新太空任务的性能。

最后，我们根据综合文献和专利调查所获得的见解，确定未来新空间开发的技术趋势。我们讨论了我们审查中出现的未来发展的关键方向，例如使用商用现成组件、越来越多地使用小型化技术和软件定义技术。
