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 first radar of the radar family AN/APG-76 belongs to is AN/APQ-92, which equipped A-6A.AN/APQ-92 is a search and navigational radar, with function called search radar terrain clearance (SRTC) to generate a synthetic terrain display on the pilot's Vertical Display Indicator (VDI), which is a large cathode ray tube (CRT) display in the center of the pilot's console, right under the gun sight.
PIGA accelerometers mounted in the AIRS (Advanced Inertial Reference Sphere) are part of the most accurate inertial navigation (INS) developed for the Peacekeeper missile. The INS drift rates are less than 1.5 x 10 −5 degrees per hour of operation, about 8.5 m per hour with the overall accuracy of the missile affected more by defects in the ...
The AN/AAQ-37 Distributed Aperture System (DAS) is the first of a new generation of sensor systems being fielded on the Lockheed Martin F-35 Lightning II. DAS consists of six high-resolution infrared sensors mounted around the F-35's airframe in such a way as to provide unobstructed spherical (4π steradian ) coverage and functions around the ...
In addition to the current position, inertial navigation systems also typically estimate a predicted position for future computing cycles. See also Inertial navigation system. Astro-inertial guidance is a sensor fusion/information fusion of the Inertial guidance and Celestial navigation.
The prime contractor was Alliant Techsystems – later merging with Orbital Sciences Corporation to form Orbital ATK, in turn being taken over by Northrop Grumman and renamed Northrop Grumman Innovation Systems – and the industry team includes Interstate Electronics Corporation. [3] By April 2018, more than 25,000 PGKs had been produced. [4]
GPS/INS is commonly used on aircraft for navigation purposes. Using GPS/INS allows for smoother position and velocity estimates that can be provided at a sampling rate faster than the GPS receiver. This also allows for accurate estimation of the aircraft attitude (roll, pitch, and yaw) [citation needed] angles.
An Air Data Inertial Reference Unit (ADIRU) is a key component of the integrated Air Data Inertial Reference System (ADIRS), which supplies air data (airspeed, angle of attack and altitude) and inertial reference (position and altitude) information to the pilots' electronic flight instrument system displays as well as other systems on the aircraft such as the engines, autopilot, aircraft ...
