INS (Inertial Navigation System) Simulation Using LabVIEW

[werder]

Overview

This VI is a simple simulation demonstrating the basic idea of INS (Inertial Navigation System), which is a gyroscope based location determining system

Description

INS (Inertial Navigation System) is a gyroscope based location determining system. By double integrating acceleration signals exact position of an object can be determined provided that initial position and velocity is known. Unlike GPS systems, INS systems works without any connection to outside world. INS systems suffer from "integration drift": small errors in the measurement are integrated into progressively larger errors in velocity, which is compounded into still greater errors in position. Advanced INS systems also support orientation tracking. This VI is a simple simulation example which demonstrates the basic idea.

Requirements

LabVIEW 2012 or compatible

Steps to Implement or Execute Code

1. Run the VI
2. Left click and hold on black rectangle and move it
3. Observe the changing position, velocity, acceleration graphs and repositioned image
