Guidance system: The MK 6 Astro-inertial guidance navigation system. Inertial guidance is most favored for the initial guidance and reentry vehicles of strategic missiles, because it has no external signal and cannot be jammed. [52] CEP: Requirement: <90 metres (300 ft). [53] (Information from flight tests is classified.)
An inertial navigation system (INS; also inertial guidance system, inertial instrument) is a navigation device that uses motion sensors (accelerometers), rotation sensors and a computer to continuously calculate by dead reckoning the position, the orientation, and the velocity (direction and speed of movement) of a moving object without the ...
The Minuteman guidance systems each required 2000 of these, so the Polaris guidance system may have used a similar number. To keep the price under control, the design was standardized and shared with Westinghouse Electric Company and RCA. In 1962, the price for each Minuteman chip was $50. The price dropped to $2 in 1968. [20]
Since so many types of missile use this guidance system, they are usually subdivided into four groups: A particular type of command guidance and navigation where the missile is always commanded to lie on the line of sight (LOS) between the tracking unit and the aircraft is known as command to line of sight (CLOS) or three-point guidance.
The guidance system of the Titan II would then configure itself to take control of the missile and ingest data to guide the missile to the target. Subsequently, main engine ignition would occur. Thrust would be allowed to build for a few seconds, then the supports holding the missile in place inside the silo would be released using pyrotechnic ...
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.
VA-111 Shkval – Original variant; GOLIS autonomous inertial guidance. "Shkval 2" – Current variant; believed to have additional guidance systems, possibly via the use of vectored thrust, and with a much longer range. A less capable version currently being exported to foreign naval forces. The export version is referred to as "Shkval-E".
An inertial guidance unit is incorporated into the autopilot to compensate for crosswind and other factors encountered in flight. The original FGM-172A was an overfly top attack (OTA) type and used a downward-facing dual laser and magnetic sensor to detect a target and trigger detonation of the warhead.
