  • A guidance system is a virtual or physical device, or a group of devices implementing a guidance process used for controlling the movement of a ship, aircraft, missile, rocket, satellite, or any other moving object.
  • A guidance system is a virtual or physical device, or a group of devices implementing a guidance process used for controlling the movement of a ship, aircraft, missile, rocket, satellite, or any other moving object. Guidance is the process of calculating the changes in position, velocity, attitude, and/or rotation rates of a moving object required to follow a certain trajectory and/or attitude profile based on information about the object's state of motion. A guidance system is usually part of a Guidance, navigation and control system, whereas navigation refers to the systems necessary to calculate the current position and orientation based on sensor data like those from compasses, GPS receivers, Loran-C, star trackers, inertial measurement units, altimeters, etc. The output of the navigation system, the navigation solution, is an input for the guidance system, among others like the environmental conditions (wind, water, temperature, etc.) and the vehicle's characteristics (i.e. mass, control system availability, control systems correlation to vector change, etc.). In general, the guidance system computes the instructions for the control system, which comprises the object's actuators (e.g., thrusters, reaction wheels, body flaps, etc.), which are capable to manipulate the flight path and orientation of the object without direct or continuous human control. One of the earliest examples of a true guidance system is that used in the German V-1 during World War II. The navigation system consisted of a simple gyroscope, an airspeed sensor, and an altimeter. The guidance instructions were target altitude, target velocity, cruise time, engine cut off time. A guidance system has three major sub-sections: Inputs, Processing, and Outputs. The input section includes sensors, course data, radio and satellite links, and other information sources. The processing section, composed of one or more CPUs, integrates this data and determines what actions, if any, are necessary to maintain or achieve a proper heading. This is then fed to the outputs which can directly affect the system's course. The outputs may control speed by interacting with devices such as turbines, and fuel pumps, or they may more directly alter course by actuating ailerons, rudders, or other devices.
  • The guidance system was a set of devices that was used to navigate a starship or other self-propelled device. On 23rd century Constitution class starships the guidance system was also known as guidance computers. In 2269, when the USS Enterprise was in orbit around the Shore Leave Planet the ship malfunctioned and Chief Engineer Lieutenant Commander Montgomery Scott was in temporary command he requested from Lieutenant M'Ress a print-out of the ship's guidance computer's last orders. In reviewing the orders, M'Ress noticed that something was very strange, and the only reason why the new orders from Scott were not being carried out was because navigator Lieutenant Arex had had all the engine controls manually locked. But as would soon be learned this wasn't the fault of Arex, but instead the fault of the planet's master computer that was suffering from it's version of a mental breakdown. (TAS: "Once Upon a Planet") Doctor Timicin of Kaelon II modified the guidance system of Starfleet photon torpedoes. Those modified torpedoes would enable him to implement his theory of helium fusion enhancement and possibly revitalize the Kaelon sun. (TNG: "Half a Life" ) In early 2373, Captain Benjamin Sisko theorized that a possible reason for the Vorta commander Kilana's interest in a downed Jem'Hadar attack ship was that she wanted to recover its guidance system. (DS9: "The Ship") The guidance system of the same Dominion ship, used by Captain Sisko and his crew to destroy a Dominion ketracel-white facility in 2374, was damaged during the facility's destruction. (DS9: "A Time to Stand") The quantum torpedo used by Red Squad on the USS Valiant to attack the Jem'Hadar battleship had the guidance system replaced by a delta radiation warhead. (DS9: "Valiant")
