To meet the global demand for spaceborne atmospheric infrared laser occultation detection, satellite orbit requirements were analyzed, and performance metrics were evaluated. Based on these constraints, satellite orbit design and performance analysis were conducted, along with extended constellation design and detection capability simulations. The results demonstrate that a two-receive-two-transmit system can achieve high-density global occultation detection coverage within 72 hours.
