With the vigorous development and in-depth application of civilian and commercial satellites, the space-based remote sensing application demands of different users become increasingly complex. However, the current space-based remote sensing services face problems such as single application mode, weak pertinence, and insufficient flexibility. Based on the analysis of the major application demands of various remote sensing users, this study proposed a space-based remote sensing application service mode based on cloud + terminals. This mode covers eight subcategories in three categories, whose characteristics and application process were analyzed and formulated individually. Last, this study presented the potential applications under two typical scenarios, namely single-person independent application and multi-person collaborative application. The results of this study will lay a foundation for the development, construction, and optimization of various space-based remote sensing ground systems and further improve the space-based remote sensing service capabilities for different users, different application demands, and different application scenarios.
