Freewave Radio Moving live H.264 Video, with 10 PWM Channels and GCS

Test Airframe: Senior Telemaster 8'


Boards:
APM
Oilpan
Arduino Pro
Freewave Radio
Eflight ESC & Motor
H264 Video Server

Joysticks that work:

Logitech G940 (no yaw on foot pedals yet) - Working on getting trim math working in the code.

Logitech Attack 3 (Tested all control surfaces working)


Other:
2 Cameras, 1 foward facing, 1 PTZ

Using Laptop with UBUNTU and Logitech Joysticks.

Phase 1:

 

a. Working Joystick Controls all surfaces of Airframe, Various buttons on Joystick change APM flight mode.
a. Completed

Added:

 

b. Working on integrating Logitech G940 Flight System

no yaw on foot pedals as off yet, does n't seem to show in the PYGAME librarys.

work to be done.

 

Phase 2: Complete
a. General Test - Live video through radio and video server.

b. Need to test and measure various bandwidth requirements for H264, frame sizes etc...

 

Phase 3: Complete
a. 4 Mile Test - 74db signal level Great video quality control surfaces respond instantly.
b. 15 mile test coming shortly.

 

Phase 4:Working on it.
Test GCS with waypoints.

 

Phase 5: Drop everything neatly back into airframe.

Eraser: are you running APM 1.02 from the zip file?
Comment by Eraser on March 7, 2011 at 3:10pm

No I am using these instructions for the 2.0 functionality....

Ah. That code hasn't been released yet and those instructions are out of date. We'll be releasing a public version this week.

wait, wait, wait. Please way more explanation about that H.264 vdo streaming.

-76dBm @ 4miles with what Pout? LOS? Antennas? etc?

Thanks in adavance.

10.5 bluewave dbi yagi on base station, 3 dbi omni on plane.  Partial Line of Site, (some trees)

1 Watt power out, (into antenna).

 

Using an H264 video encoder and an ordinary analog camera.  .

Looks like a nice setup for vdo streaming.

I suppose freq is somewhere 900 or 868Mhz?

could you post a link of the radio module and vdo encoder board (supposed are different) used?

what kind of bandwidth do you need for the camera? I see that the freewave modem exist from 115K to 1.2Mbits/s . which one are you using? I also see that this product is under "government radio". was there any problem to access it?
Comment by Eraser on March 7, 2011 at 4:45pm

I need between 50kbps and 700kbps depending on how much motion exists in the frame...

For instance if camera is showing alot of the airframe, such as tail mounted, it uses a whole lot less bandwidth as it doesn't have to update the areas where the airframe doesn't move much as often.

They have government versions.....  This one is not.  I am using the 1.2Mbits/s version.
