Posted by someone on the V+ Owners Facebook Page, I like the new GPS shielding

Because its not the Gps causing the problem its the camera .My Gps works 100% perfect untill i switch on the camera .HunterSK said:Thanks for the photos AsiaFlyer and saltire.
I'm wondering, what signal leads are the ferrite beads applied to? Any idea why they didn't have a ferrite bead on the GPS lead itself?
Not too bad, they are sometimes fitted on camera USB leads for example.varmint said:4wd said:What are those ferrite cores fitted to, we could do that perhaps.
Those things can be fairly heavy. I'm not even sure I'd want those from the factory, but I'd be curious to know how much they weigh.

Nathan Carter said:I'm wondering what is the explanation why some of us don't experience any loss of GPS satellites reception when starting video recording or using the camera in anyway?
HunterSK said:Yeah I use the same card. What would be interesting is remove the camera completely (or turn it off), and see how many satellites are picked up. I think removing the camera gimbal from the Vision+ may also stop the data telemetry being sent (I haven't tried it myself, so happy to be corrected).
The interference is coming from but it's definitely within the camera system. My guess is that the recording of video causes more of the internal logic to function and it just spews more RF energy out to the rest of the aircraft.
HunterSK said:Hi Nathan,
Have you tried tucking the GPS cable underneath the original GPS shield? See if that makes any difference. People have also tried installing a second GPS shield, and as you can see the new Vision+ (ver 2) has this done as well.
After fitting the ferrites i did not see much difference whilst pressing the recording button but i tried the anti static sheilding on top of the camera and it has made a difference so i am going to line the bottom of the quad with copper sheilding and open up the camera and line it with ferrite sheeting which is £25/$40 for a small 100mmx100mm sheet .HunterSK said:OK thanks saltire.
According to datasheets from common ferrite beads, they could be trying to attenuate 1 - 300Mhz spectrum. It's impossible to tell unless the beads are identified.
Have you noticed any difference with your beads on?
