Sentinel Satellites

Sentinel satellites are a specific classification of military reconnaissance satellites. Their particularity is that these satellites rely purely on passive sensor systems. No radar, lidar, or anything, just a lot of sensors, cameras, ect, to get every wave and particle coming their way.
Sentinel satellites are particularly famous for being one of the few systems capable of tracking stealth ships, albeit not necessarily reliably. They are also one of the few sensor systems that allow for mid-course acquisition of missiles -missiles who have already done their initial burn and are travelling 'dark', usually at extremely high speeds-, and are thus a core part of the early warning systems of Earth and Mars for a Relativistic Kill Missile or interplanetary missile attack.
Most sentinel satellites are dispersed in clouds around particularly sensitive locations, and then spread out in rings around solar systems. Thanks to their complete lack of emissions, they also make excellent long range spy satellites, and they have been used extensively in this role in the Alpha Centauri system by both the European Federation and the United Interstellar States, as well as their respective allies.
