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 ...
Space Integrated GPS/INS (SIGI) is a strapdown Inertial Navigation Unit (INU) developed and built by Honeywell International to control and stabilize spacecraft during flight. SIGI has integrated global positioning and inertial navigation technology to provide three navigation solutions : Pure inertial, GPS -only and blended GPS/INS .
Inertial navigation unit of French IRBM S3 IMUs work, in part, by detecting changes in pitch, roll, and yaw. An inertial measurement unit works by detecting linear acceleration using one or more accelerometers and rotational rate using one or more gyroscopes. [3] Some also include a magnetometer which is commonly used as a heading reference.
The YJ-83 uses microprocessors and a strap-down inertial reference unit (IRU); these are more compact than the equivalent electronics used in the YJ-8 and the export C-802, allowing the YJ-83 to have a 180-km range at Mach 0.9. The missile is powered by the Chinese CTJ-2 turbojet and is fitted with a 190-kg high-explosive fragmentation warhead.
The Redundant Strap Down Inertial Navigation System/Inertial Guidance System of GSLV housed in its equipment bay guides the vehicle from lift-off to spacecraft injection. The digital auto-pilot and closed loop guidance scheme ensure the required altitude maneuver and guide injection of the spacecraft to the specified orbit.
Inertial Measurement Units (IMUs) are the primary inertial system for maintaining current position (navigation) and orientation in missiles and aircraft. They are complex machines with one or more rotating Gyroscopes that can rotate freely in 3 degrees of motion within a complex gimbal system.
The LN-3 inertial navigation system is an inertial navigation system (INS) that was developed in the 1960s by Litton Industries. It equipped the Lockheed F-104 Starfighter versions used as strike aircraft in European forces. An inertial navigation system is a system which continually determines the position of a vehicle from measurements made ...
The stage also houses the flight computers and Redundant Strap Down Inertial Navigation System of the launch vehicle in its equipment bay. The digital control system of the launcher uses closed-loop guidance throughout the flight to ensure accurate injections of satellites into the target orbit.
