Hi,here is my antenna tracker. A simple BCAC (brain controlled analogic cut :D) wood case. Simply, cheap, working.In the video a first test with an EZ* flying autonomous, this way I can record the AT working.Richttp://www.vimeo.com/8054260
Morli, tilt servo is faster. Is for that it moves rapidly and it seems less smooth.
Austin, this is homemade. Costs? Some wood and glue. Electronics are an Ardustation, a patch antenna and the mentioned servos.
Mark, I guess that in flight the resolution is more than enough. Farther you go wider is the window. Btw the antenna I mounted is an 8dBi patch with 75° horizontal and 65° vertical beam width.
GWS 125 1T Sail Servo has slow response about 1/2 normal speed spec 0.26s/60deg & 1.56s/360deg, I got one last week and tested it with a Hitec HPP-21. A very good servo tester/ programmer @ $27 but requires usb on Win PC, but not on Mac-OSX, Looks like it works great for our application. When testing slew speed, if servo is commanded to go too fast it stops...
So a slow update should work fine, maybe up to 6hz, unless you have narrow bean yagi or a dish antenna. Patch antenna view is 30deg wide. I may use both a 900mhz 15dbi yagi & 8dbi patch with signal strength diversity. Maybe a 1/2 wave turnstile on UAV if I can make one...
Hi am new to this marlarke but are you selling the tracking system or is it home made? I would love to own something like that. wot was the costs to build suck a system?
Comments
thank you very much. Please let me know about your work !
Ric
this time I mounted a videocam instead aerial.
Ardustation is driven by an UAVDevBoard plane.
Best regards,
Ric
thanks for your useful info.
For those interested here is the link to this product.

Rana, thank you too! The code is the official release v1.3, tuned for my servos, of coarse.
You have written very less in blog, put more words.
BTW where is the code ?

I'm using a GWS S125 1T/2BB for pan and a standard Graupner C5077 for tilt.
