– A 2025 paper presents "a unifying framework consisting of five mixed-integer linear program formulations" for optimal constellation configuration design, capable of handling "various metrics and mission scenarios, such as percent coverage, average or maximum revisit times, fixed number of satellites, spatiotemporally varying coverage requirements, and ground-, aerial-, or space-based, static or mobile targets".
Higher radiation exposure (Van Allen belts), higher launch cost than LEO Broadcast TV, weather monitoring, missile warning – A 2025 paper presents "a unifying framework
