Inertial navigation system - Wikipedia
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 ...
What is an Inertial Navigation System? How does it work?
2014年3月15日 · Inertial Navigation System it uses a planes motion as detected by on-board accelerometers and gyroscopes to find where it is going using no external reference points. A plane has a certain known heading and speed, when the planes makes a turn, hits a headwind,... accelerometers and gyroscopes will detect the change in motion and orientation and ...
This report provides a broad overview of inertial navigation, focusing on strapdown systems based on MEMS devices. It describes the error characteristics of gyroscopes and accelerometers, and how to reduce drift in inertial systems using sensor fusion and domain specific constraints.
Inertial Navigation System - an overview | ScienceDirect Topics
An inertial navigation system (INS) is a self-contained technique to estimate vehicle position, orientation, and velocity by means of dead reckoning. INS includes motion sensors (accelerometers) and rotation sensors (gyroscopes) where position and orientation of the vehicle is estimated relatively to a known initial starting pose.
