A planetary defense system is a system of defense platforms and countermeasures designed to protect a planet from attack or invasion.

Examples of Federation defense systems

2367: In early 2367, a Borg cube en route to Earth encountered a small fleet of ships in orbit of Mars, dubbed the Mars Defense Perimeter. It was easily dispatched by the cube. (TNG: "The Best of Both Worlds, Part II")

2369: When Deep Space 9 space station was taken over from the Cardassians by the Federation in 2369, the station itself became a planetary defense system for Bajor, and one of its main obligations was to protect the planet from hostile attacks. (DS9: "Emissary")

2374: Betazed had antiquated planetary defense systems, which proved little match for an invading Jem'Hadar army during the Dominion War. (DS9: "In the Pale Moonlight")

2375: The planetary defense system of Earth, in 2375, was not strong enough to hold back the surprise Breen attack that occurred. Their ships inflicted considerable damage on Starfleet Headquarters. (DS9: "The Changing Face of Evil")

Examples of non-Federation defense systems

2152: The Romulan Star Empire used cloaked mines as a type of defense system, as early as the 22nd century, to prevent alien invaders landing on their planets. (ENT: "Minefield")

2267: In 2267, the USS Enterprise (NCC-1701) encoutered Apollo's hand near the planet Pollux IV. This enormously-powerful force-field was capable of stopping the ship approaching the planet, preventing it from firing its weapons, and also preventing escape. (TOS: "Who Mourns for Adonais?)

2364: The Aldeans, until 2364, used a high-powered repulsor beam to repel any unwanted ships from the planet's orbit, as well as a powerful shield and a cloaking device. (TNG: "When the Bough Breaks")

The Echo Papa 607 weapon system of Minos could act as an effective planetary defense system, repelling land-based or orbiting invaders. (TNG: "The Arsenal of Freedom")

2369: The moon in the Gamma Quadrant, home of the Ennis and the Nol-Ennis, had a sophisticated array of orbiting satellites, which inhibited transporter functions, and also actively seeked out and attacked orbiting vessels. (DS9: "Battle Lines")

2372: After the Klingon invasion of the Cardassian Union, the Klingon Empire deployed orbital defense systems around the planets they had captured. (DS9: "The Way of the Warrior")

2373: Chancellor Gowron moved the Klingon military headquarters from Qo'noS to Ty'Gokor. Ty'Gokor is protected by a powerful defensive shield and a tachyon detection grid, along with a large number of ships.

2374: During the Dominion War (2373 - 2375), the Cardassians had developed an orbital weapons platform system, to protect undefended regions of their space, such as the Chin'toka system. (DS9: "Tears of the Prophets)
