    Inertial Navigation Integration FIlter

    So you don't have to worry about this..I haven't been a student for some time... I'm asking if the heading needs to be part of the state vector as I saw different approaches that did not use it. And my experience with Kalman filters doesn't go too far. I have read about it but it's the first...

    Inertial Navigation Integration FIlter

    No, it's not for school. I graduated 2 years ago from university. Why is everybody asking me if it is for school? It shouldn't be?

    Inertial Navigation Integration FIlter

    Should also the heading be part of the state vector? How can I determine what is vital to be in the state vector and what can be skipped? Thank you

    Inertial Navigation Integration FIlter

    Thx for the help. :) For a Inertial system with a gyro and an odometer, should I introduce more states then [position velocity acceleration]? Should I introduce in the state vector also the heading, gyro and odometer bias? and i get a state vector like [position velocity acc heading gyro_bias...

    Inertial Navigation Integration FIlter

    The process noise is added to the state update equation: x(+)=x(-)F+w (w process noise) and the measurement noise is added to the measurement equation: z=Hx+v (v measurement noise) My question is how to determine the values of v and w? You determine the values experimentally, analytically or...

    Inertial Navigation Integration FIlter

    It's not for school. It's a project i'm trying to do im my spare time. So I'm far from the topic? Can you give me some guidance please, so I can clear some of the confusion? Im trying to integrate the output from an IMU(3 axis gyro, yaw axis accelerometer and odometer if needed) with GPS. Where...

    Inertial Navigation Integration FIlter

    So I should introduce an estimate in the equations the measurement and process noise? Like z=Hx+w (where w is the measurement noise) and x(+)=Fx(-)+v (where v is the process noise)?

    Inertial Navigation Integration FIlter

    Hello, I am trying to create a filter that can integrate inertial measurements with GPS measurements. My inertial sensors are a yaw axis gyro, an odometer, and possibly a 3axis accelerometer. Could you please help me with some guidance? I have read papers, articles and books on the subject but I...
