The game does not take the sensor range of ships in orbit into account after loading. However by ejecting and orbit reentry of the ship the range is updated.
See the difference between the screenshot. First screenshot shows the sensor range after a load with the Overseer in orbit. Second screenshot shows the sensor range after the Overseer was ejected and send back to the planet.
Take special note of the enemies ships that are now suddenly visible.
It affects the range in both the main view as in the mini-map.
