Antena Tacker Again...

[kelly]

I wish the RVOSD did not have to be moving to get a good lock on home and where the plane is . it needs the magnometer working . and so much drift with the GPS antenna it comes with . I think I will try the bigass dragon osd's GPS antenna. my plane can just be sitting there and then its 12 or 30 feet from home but its still in the same spot

Does anyone have accurate measurements for the GS box in mm please? Want to get a nice hole cut out in my gs ready for it

[Squawk]

Hey Baka,

133 x 81 x 29 mm

(133mm excluding the screws sticking out on both long sides, 1.5mm, 1mm below the front plate, so 136 with the screws included, but will leave a space between RVGS case and hole in the gs panel you want to make)
(29mm including the rubber feet of 4mm thickness, so 25mm without the rubber feet)

Grtz,
Koen

Thanks again Squawk

Good detail!

It's all in the details...

Alex/or any one ?? out of these two pans which would work better for the RVGS ??

and I was thinking of using this as the tilt

and I think I will go with metal gears and a 13.5 to 1 gear ratio on both pan and tilt

I guess Im asking this because I want to know what kind of pot would aim the tracker better. right now Im using a http://www.servocity.com/html/spg785a_top_mount.html for the pan

Finally I have my antenna tracker!

I have only done a quick ground test but have noticed for following

*I am not using the av cables supplied as I have 3.5 to 3.5mm jack cables as needed. At first I had no video or telemetry and it really confused me for some time until I pulled the 3.5mm jack out a couple of mm from the input and it made a proper connection. Might have to hunt around abit more another cable as I dont like having important cables not secured properly.

*HappyKillmore GS shows altitude of 100+ meters when telemetry says zero

*If you need to calibrate again (Heading offset) the antenna does not move to natural forward position making it easier for you to line up

Im holding off judgment on the actual tracking till I get a chance to fly, ground tests...ummm, lets just hope its better in the sky

It sounds like the different poles on your stereo jack do not match up with the RVGS. Perhaps the audio and video poles are switched. If your cables are plugged in all the way, can you switch the audio and video to get the telemetry?

If the ground is not the same pole, then I wouldn't bother with the existing cables. I'd try to find ones that match the RV cables.

If you are using Lawmate Rx, the audio and video are transposed with the RVGS, so you need to cross connect to get it to work.

Sounds like you'll need one of these:
