This paper provides an overview of the current status and future trends in remote sensing satellite data transmission technology. The article begins by introducing the developmental history of remote sensing satellite data transmission. It then further elaborates on the technologies involved in remote sensing satellite data transmission, detailing key aspects such as data compression,data encryption, data framing, data encoding, data modulation, and data transmission. Subsequently the paper analyzes the challenges faced by remote sensing satellite data transmission, such as bandwidth limitations, signal processing, real-time requirements, and data handling. It also summarizes strategies to address these challenges, such as adopting laser-based data transmission, more complex modulation schemes, and multi-source fusion with computational transmission. Looking ahead, the paper envisions future trends, including inter-satellite laser relay transmission, on-board computational transmission, and the application of computational constellations for intelligent in-orbit fusion in remote sensing satellites. Research indicates that remote sensing satellite data transmission technology will evolve towards higher transmission rates, higher reliability, more convenient data processing, and more intelligent mission workflows.
