Team OSAM just finished surveying a couple thousand feet of road with our high resolution camera in very narrow canyon. We also recently did a multiple uav formation flight (my baby). In addition to this austin recently wrote some new functions for the paparazzi navagtion scheme. The two function are bungee takeoff which will automatically turn on the throttle after the bungee stake has been cleared along with the bungee detaching and also a flower function which makes the plane fly continuously in a pattern that resembles a flower.
We are currently working on flying a 5 miles sqaure section of area using a high resolution camera to geo-reference the photos in RGB and NIR. In addition to that we are working on a navigation function which will survey a polygon (sector) in a much more precise manner than before and that has the ability to know when it is finished. This is all using paparazzi of course.
