The focus of the VelocityUKF is to provide a model-aided linear and angular velocity estimate. Due to the model-aiding the velocities can be provided in a high frequency.

The PoseUKF is a model aided inertial localization solution for autonomous underwater vehicles. As minimal input the filter relays on rotation rates and accelerations from an IMU and velocities from a DVL. Given force and torque measurements an AUV motion model aids the velocity estimate during DVL drop outs. ADCP measurements further aid the estimation in cases of DVL bottom-lock loss. Given gyroscopes capable of sensing the rotation of the earth (e.g. a fiber optic gyro) the filter is able to estimate it's true heading.

This C++ library uses cmake and can be compiled within ROCK, ROS or independently. The following instructions have been tested on Ubuntu 16.04 (Xenial).

Make sure that the Ruby interpreter (recommended version 2.3) is installed on your machine.

mkdir rock
cd rock
wget http://www.rock-robotics.org/autoproj_bootstrap
ruby autoproj_bootstrap git git@github.com:rock-core/buildconf.git
source env.sh
autoproj update # All configurations can be answered with the default parameters besides of the Rock flavor. This must be set to master.

NOTE: Please select master as Rock flavor. All other parameters can be the defaults.

sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu xenial main" > /etc/apt/sources.list.d/ros-latest.list'
