| Abstract: |
| Navigation technology is critical to humanity's advanced exploration and development of cislunar space. Traditional navigation methods, such as ground-based tracking and control, face significant challenges in supporting cislunar spacecraft operations. Issues such as high signal transmission delay, weak navigation signals, and poor observation geometry reduce both navigation accuracy and real-time performance, making it difficult to meet the requirements of complex deep space missions. Space-based navigation techniques, including inter-satellite links, offer new approaches to overcome these limitations. Based on the classification of the characteristics and requirements of cislunar space navigation, the current status and features of space-based navigation technology are discussed. Future development directions, including advances in hardware, algorithms, and novel navigation architectures, are also projected, providing valuable insights for the development of cislunar space navigation technology. |
