How To

There is alot to the construction of the Wireless Aerial Surveillance Platform, far more than can be adequately covered in an email or even on a simple webpage.
There are some fairly detailed build photos and specs on our web site.
Obviously, we aren’t able to provide detailed plans and blueprints.

Here are the specifications

Here are some sites which might help you if your goal is to build your own drone:

    Hello Guys..you do a GREAT JOB. i want to ask you if you have some time to answer me, if you do some programming in your model. Thanks.

      Great question :) There is surprisingly little real programming work involved outside of a few basic scripts which serve to glue parts of the avionics and payload systems.

      The Ardupilot really only requires some modifications to certain constants within the code to suit your airframe’s flight characteristics (this is not as easy as it sounds, lots of trial and error) and some software and hardware “tweaks” depending on your intended uses to enable things like loiter on command and on-the-fly mode switching for “over the horizon” operation (don’t do this without verifying you won’t go to jail.. you probably will).

      The payload is all managed via USB through a host of open source tools like Backtrack Linux, OpenBTS, AirCrack-NG, etc. These tools are coodinated using a series of scripts written in Bash and Python which manage the flow of command data and tool outputs between the operators, equipment and backend processors. These scripts are responsible for managing the various control channels (PPP tunnels, OpenVPN, etc) and the movement of data files, logging information, telemetry and other data automatically from the aircraft to the ground and the processors, as well as automatically provisioning the PBX for the IMSI catcher. It is basically a flying wireless linux laptop with a bunch of USB peripherals controlled via SSH.

      Those are essentially the only “programming” activities that we did to achieve the basic functionality. Now the beauty of the platform is the ability to extend its capabilities by adding tools or creating capability onboard natively. So if we find that there is a need to write code on the aircraft we can do it “on the fly”, although its a poor use of flight time to compile code in the air :)

      Hope this answers your questions. Thanks for the great post!

    sorry.. And what the programming do about on the model. Thanks
