Homework Statement
Given Ax,Ay,Az . I need to find the Vx,Vy,Vz ... The Coordinate Frame is Vehicle Axis System .. I have actual Speed to compare once i get the Vx,Vy,Vz ... The vehicle starts from the rest i.e Speed is zero and Accelerations are sampled at 0.05 seconds///
This is not a homework question
Homework Equations
Vx = Vix + integration(Ax*dt)
Vy = Viy + integration(Ay*dt)
Vz = Viz + integration(Az*dt)
V = sqrt(Vx^2 + Vy^2 + Vz^2)
The Attempt at a Solution
I have done the steps above with Initial velocity components as zero and did get some solution (Vx,Vy,Vz) , But they are not matching with that of actual speed .
If I just plot Vx and actual Speed , Its following the same trend as actual Speed of vehicle but has higher values...
What I am assuming is that , Do I need to do any coordinate conversion as it is Vehicle Body frame to Navigation frame.. Kind of... Please comment on this
Please let me know if anyone needs the data and also the Code which i wrote to calculate the velcoity
