Objective: Through the FACSAT program, the Colombian Air Force aims to promote the independence of the Colombian space initiative. This article proposes the operational orbit for the FACSAT-2 satellite mission, intended for capturing images facilitating the detection and classification of Colombian terrain using satellite technology. Materials and Methods: To advance aerospace technology, this study recommends a specific operational orbit for FACSAT-2. The selection considers operational requirements, geographical location, launch windows, commercial orbit availability, and data from FACSAT-1 and simulated scenarios. Results and Discussion: The operational orbit is crucial in satellite system design. Restrictions on elevation angles and considerations regarding total accesses, access time, among others, reflect a comprehensive approach, strengthening the foundation for selecting the operational orbit. Conclusions: Criteria for the FACSAT-2 operational orbit were defined, addressing inclination, total accesses, access time, revisit time, altitude, and launch window. Simulations indicate that an inclination ≤ 40° offers optimal performance, with an optimal altitude of 550 km. The orbit with a 23° inclination, 550 km altitude, scheduled for 2022 Q3 from India, stands out for providing maximum accessibility and coverage for Colombia.
