Furthermore, the experimental results based on the X-band STWE-SAR airborne system not only demonstrate the schemes effectiveness but also indicate that it holds great promise for future STWE-SAR missions. The tutorial provides a straightforward way to test the efficacy of vision-based navigation using depth cameras and an IMU, with the option to include wheel odometry.This tutorial will explain step by step how to configure the ROS navigation stack for your robot. = While this initially appears to be a chicken-and-egg problem, there are several algorithms known for solving it in, at least approximately, tractable time for certain environments.
