"What apm firmware did you use? The line navigation was spot on, very nice. Can you post a photo of the camera mounting as well?"

Longitude errors in flight planning of mission planner
Started this discussion. Last reply by Michael Oborne May 19, 2012. 6 Replies 0 Likes
Everyone and especially Michael,I believe that APM mission planner has an error in calculating flight plans in terms of correcting for longitudinal distances with respect to latitude. For instance,…Continue

Anyone investigated or heard of this airframe? Found at www.thewingsmaker.comIt looks similar to the skywalker in terms of a pusher T-tail foamy, but it has…Continue

I have an APM with 2540 IC running APM 2.12 in a skywalker with Hitec Auroa 9 RC. The hardware is extremely unstable, APM is very frequently losing all configuration, about every 3rd flight. I have…Continue

Profile Information
- About Me:
- I am an aerial mapping and aerial photography specialist, and just getting involved in unmammed aircraft. My background is in geology, where I have always been interested in mapping and earth science. I learned to fly in 1986 and have been a pilot ever since. I migrated to manned aerial surveying and geomatics in 2000 working as a pilot, sensor specialists, and flight department manager. I am not an engineer, but sometimes think I should have gone that route based upon my interests. I am fairly knowledgeable about professional aerial surveying and photography having worked in the field for many years, as well as consumer grade aerial cameras and photography for low cost applications. I am very familiar with high end survey grade GPS and IMU systems, and some remote sensing such as imaging spectrometry, thermal and IR imaging. My professional interest is in airborne remote sensing and photography, and recognize that I should become knowledgeable about unmanned aircraft. I was an avid RC pilot 25 years ago, but a lot has changed.
- Tell us a bit about your UAV interest
- Interested in UAV mapping, photography, remote sensing, and data collection. Currently just getting started with a skywalker. I have to get back up to speed with basic RC flying skills, then FPV, and then UAV. I also have a very strong interest in camera mount stabilization and hope to configure an ardupilot mega to stabilize a manned aircraft mount.

Roll Stabilization for Vertical Photo Mapping
Posted on June 9, 2011 at 3:00pm 0 Comments 2 Likes
I completed a first test flight for roll stabilization for vertical mapping. It dramatically helps aiming the camera down, and should help with optimizing/maximizing line spacing and acheiving better results for any stitching and photogrammetry processing by getting generally vertical rather than slightly oblique photos.
I used microrax.com for building the mount itself, this is really handy stuff for these types of projects, it is the tiny version of T slot tubing. Once you use it for…
Photomapping Camera Stabilization using Silicon Gel
Posted on June 9, 2011 at 5:30am 8 Comments 3 Likes
I am new to this site within about the last month, trying to get up to speed for aerial mapping using a UAV, currently using ArdupilotMega with a skywalker for vertical mapping. In mounting a small camera inside the fuselage of the Skywalker, I experimented with silicon gel for vibration isolation, which appears to be promising. The current testing used a Canon SD1200 IS camera because it was available, but I would plan on using something with a larger imaging…

Rigel said… Hi Cliff,
I'm working on camera stabilization as well. I've implemented Alpo's code but I noticed that the roll channel creates a lot of jitters. Is this a problem you've run into as well?
I see pictures of a crashed skywalker...what happened?
Attached below are a coupe of pictures of my setup with a belly pod of the 2 axis camera nacelle. All the best.

Cliff, I've attached a few pictures of the setup. If you have any questions, don't hesitate to ask.UAV%20small.rar

By the way Cliff, I've been building this drone for topo mapping purposes. Any advice on your part would be welcomed.
