"Edan You should repost this as a BLOG entry. Include the video of the Telemaster UAV as the first entry in the blog. It will get to the main DIYDrones page and get a lot of coverage. Market the story and the usage of the amateur UAV in SAR. A lot of…"

Radar or other aluminum sensor arrays

Hi everyone,I am volunteering with a search and rescue group looking for a downed US missionary pilot lost in the Venezuelan jungle. His name was Bob Norton and his aircraft went down two years ago with 7 total onboard.You can read about the search effort here: www.findingbobnorton.org The team has been down twice to search. We've conducted flight simulation and satelite imagery analysis to try to identify possible areas of interest where the the…See More

About Me:
Been slowly building up my UAV and now have computer control from the base station.
Hometown:
Redlands, CA

Hi, my UAV is controlled from the ground station. User control is via a joystick attached to the laptop, application captures and converts the joystick axis throws and converts them for each corresponding servo throw, and pushes the channel value throw out through a modulating USB unit to the buddy port on my RC TX. Otherwise I can have the computer control the rudder and elevator from waypoint to waypoint. This has only been achievable when I stay close enough to use a blue tooth gps device as I am haven't created anything to send the feed back to me.
Have onboard camera gimble for pan and tilt. Live video is streamed back to the application.

Application:
3D and 2D, can change between following a 3D model plane or heads up display (OpenGL). Switch between flight or camera mode. Pressing the trigger captures a jpg from the video feed, creates a point on the map and attributes the point with the image. Can switch between flight mode and camera mode so that I can pan and tilt.

Had a friend start on the electronics for a tri axis accelerometer to capture pitch/ roll/ yaw, broadcast this back to me along with the GPS NMEA sentences. However this failed and I have become impatient in waiting.

So, I had a read and watched Paul Hubner's Parrallax Propeller project. Awesome Paul. Basically what I want to develop. I have everthing ready to go on the software end, just need the axis and positional relay from the plane.

I write code by day (and night). The 3D and 2D components are managed code components we produce at work. All of the flight control, video capture and OpenGl etc is all my custom coding, C# object oriented classes. I'm going to rewrite it in C++ to lean it all down and gain performance.

Future expansion:
Camera viewing offset currently on 2D map only (sorry not shown in screen shots). Writing code for 3D viewable extent cone from plane to surface. Will calculate XMax, XMin, YMax, YMin of image and georectify (draw onto correct location) for captured images.
video goggle head movement tracker to relay to onboard video gimble.

I would like to attempt the RC Solar powered amateur altitude record and or distance record.

Looking forward to reading more about what others are doing. Would be very interested in partnering up efforts.

Cheers,
Edan

Tracking your UAV in a 3D environment

NB: Edited earlier post with new link to script download site. Also, if you check the arcscripts site there is a flip book animator for the application that will iterate through georectified images in the order you set based on a timer, or manually (this allows you to move backward and forward), or you can click the image in the list to have it display. Allows you to set the transparency of the image so you can see the base layers beneath. Will post the live GPS feed task for ArcGIS explorer to… Continue

Hey guys,
this isn't a UAV post. I just wanted to point you at an inspirational RC aircraft site from a guy near me. His write ups are amazing, the level of detail and lists of all hardware is brilliant.
Check out Don's experimental projects once you've seen his aircraft videos.

Hi Edan, My group (Pict'Earth) is also based here in SoCal, and would be interested in hooking up with you to see how we might be able to work together.

Hi Jeff.
i've taken a look at your website before actually. Definately interested. Will take a look at Carbon tonight. Need to take another look at Google Earth also as I see they have a HUD flight sim now. I do a lot OpenGL here and my ground station has a fully funtional HUD for my plane.
