Space-based optical observation is an important approach to obtain GEO target information and affected by a lot of constraints. In this paper, various constraints in GEO proximity optical observation are studied in detail from three aspects of observation distance, observation angle and angular velocity. In terms of observation distance, based on Johnson Criteria and STK/EOIR simulation, it is determined that the observation distance for proximity optical observation is no more than 25 km. In terms of angle constraints, the relative position relationship between sun, moon, earth, spacecraft and target, that affect the geometry of optical observation, is analyzed, and the sun illumination angle is restricted to no more than 40°, the earth cannot appear in the field of view, and the target must appear in the field of view.
