Special Issue Information

Dear Colleagues,

As a non-contact information acquisition technology, remote sensing leverages principles such as electromagnetic waves and lasers to develop various types of sensors. These sensors, deployed on platforms such as satellites, drones, and ground-based observation stations, enable the three-dimensional exploration of Earth's spheres from different distances, angles, and levels. Due to its strong compatibility with other fields, remote sensing technology has played a significant role in resource management, precision agriculture, precise ecological management, smart cities, disaster prevention and mitigation, and other domains in recent years. This has greatly contributed to the sustainable and healthy development of society and the economy.

This Special Issue of Sensors aims to gather original research and review articles on new technologies, advancements, methods, applications, and challenges in the field of remote sensing.

Potential topics include but are not limited to the following:

  • Development of remote sensing sensor payloads;
  • Large-scale production technologies for remote sensing satellites;
  • Modularization and low-cost technologies for commercial aerospace;
  • Hyperspectral image processing techniques for target detection, classification, and characterization;
  • High-resolution image information extraction and change detection;
  • Fusion and calibration of multi-source remote sensing imagery;
  • New methods for processing and analyzing remote sensing data, such as machine learning and deep learning;
  • Earth observation and artificial intelligence;
  • Precision agriculture;
  • Farmland extraction and classification;
  • Crop yield prediction;
  • Monitoring of crop growth conditions;
  • Carbon sink estimation;
  • Assessment and recommendations for wetland ecological quality.

Acquiring high-quality images from space at low-latitude areas is challenging due to the orbital requirements of the satellites and the frequent cloud coverage. To address this issue, a low-latitude remote sensing satellite constellation—the Hainan Satellite Constellation (HSC)—was conceived with a spatial coverage-priority concept. This constellation integrates sensors with multispectral, hyperspectral, radar, and Automatic Identification System (AIS) capabilities for marine vessels with an onboard image processing technology. The design is tailored to the tropical/subtropical region. Once HSC becomes fully operational, it will provide high-frequency coverage in low-latitude regions, with a primary focus on ocean observations. The first four optical satellites (HN-1 01/02 and WC-1 01/02) were successfully launched in February 2022. They boast unique application characteristics, including satellite networking for ocean observations over large areas, onboard image processing and modeling for ship detection, as well as the synergy of onboard sensors with optical and ship AIS capabilities. This study focuses on the technical design and proposes implementation strategies for HSC, encompassing its technical characteristics, composition, and capacity. Additionally, it explores the construction of this satellite constellation and its uses while providing insights into potential follow-up satellites. Full article
