Definition
The minimum angular distance from the Sun at which the camera can operate normally; it is complementary to the maximum observation phase angle. When the Sun is near the camera FOV, stray light overwhelms target signal and the camera must shut down. The paper calculates a demand of 50 degrees for GEO observations from cislunar libration points, with maximum observation phase angle approximately 128 degrees. This angle is critical for determining blackout durations in constellation design.
Application Value
This concept provides fundamental support in cislunar space research and mission design. In practical applications, the appropriate analysis method should be selected based on specific mission scenarios and constraints.
