Between 3 Naza systems, a couple 350QX's, an APM and a vector, not once have I lost a lock at the field. I do take great care to route my GPS cables as far away as possible from any power sources, make sure it has a 100% lock on the ground (for naza, no red lights, plus a rapid series of green flashes, then another set for home lock). Which system are you running and where do you lose the lock? Your backyard? The field? A park?

fdevon just short flights. I am running nazi. There is gps to start then when in flight i notice loss of gps. I bring it back closer then i will get gps again. Not always do i loose gps. Just worried that when i start way point trips i loose gps. I have read different things to improve signals. I will try to stay in touch to set up a meet to go over my drone to see if everything is all set. I upgraded the drone to latest version. Controller is still older one, and not the new model.Camera works great. Let me know what you think, You can email me as well happy123@shaw.ca
thanks

What are you using for a camera and transmitter? How are they oriented as compared to your GPS?

Does it use a 2.4 Ghz WiFi signal for your video?

There's your problem buddy. The whole WiFi and GPS issue first really came to light when people were running go pro cameras on the 350QX quad. The go pro has WiFi and when left on, would cause GPS drops and all kinds of funny situations to occur. There's lots of variables involved, but the problem tends to go away when any transmitting equipment is moved as far away as possible from the GPS antenna, and everything transmitting is shielded by copper. Not a problem for a go pro just hung on the bottom of a 350QX, bigger deal when you want the signal to actually transmit so you can do some fpv with it. The only stuff I've ever really heard of being successful for some reason is the DJI  stuff on 2.4, yet random, unexplained other issues with transmitters at the field seemed to happen as well (loss of signal) when those units were being used.

No, you don't, but it's exactly the same issue, just in different packaging

I really don't know the answer to that to be honest. I don't think it's a firmware thing, I would tend to think that it's more of a shielding and interference issue, as you said, all is well until you transmit video. Usually the DJI stuff seems to just go, it's everything else that was experiencing that type of interference.

So far, unless the weather really turns to crap, I'll be out there on Saturday, 11-12 is when I usually aim to get out there

Post by: brian sinclair on May 28, 2015, 08:04:52 PM

Also, if you have a portable hard drive or USB stick, load up the firmware updates that you downloaded and bring them with you, I'll have my laptop and It has no issues connecting to a naza for firmware updates and stuff so we can double check programming and update it. I did some Google searching and it seems like your particular model has lots of GPS issues, more than anything else I can find for anything else DJI, but there's a ton of suggestions out there for ways to improve it
