I always shield the GPS/magnetometer with some self adhesive aluminum foil to protect it from RF noise. And it works very well. Even above the caddx tarsier which usually blocks the GPS signal totally. 👍 On my betaflight builds I simply put the single bn180 GPS/ without magnetometer on the rear arm, and it works pretty well.👍
Several of my quads have the GPS on the top of the HD (GoPro) Camera mount, never had a problem, always get at least 12-14 satellites. I was getting 21 the other day way out in the middle of nowhere. The main thing to remember is to twist the GPS wires then wrap or shield them. I just use shrink tube, using the heat also molds it to the contour shape of my quad and camera mount, keeps it tidy. I also mount on my strap with one but that tends to wear the wires out. I do love the rear GPS mounts the best for sure.
I put mine on a mast at the front of the quad because my 1.2g vtx is where you have your GPS....The Rx antenna is also at the front of the quad ...for maximum separation...It works great on iNAV...My fpv camera doesn't affect either reciever...
good points, however if you do fly digital, you SOL, the DJI Signal will completely cover the RF range, and the other downside is if the frame is rather "long" like if designed for HD .. the "ass" is getting quite long... so I did the second worse thing and mount it on the front arm, but yes your propeller arguments are very valid.
in my experience , worse place to put a gps is in the back, under your 5.8G antenna. so I will disagree with you in this one. I had best results on top of my gopro 7 or on the arm with a 3D printed mount. happy flying.
Unrelated to present subject but I watched your 2 videos regarding Frsky and their new Access protocol and general bad faith in regards to leaving Accst in the dirt. I just finished installing Crossfire and now the RM9 is sitting on the desk doing nothing. Thanks for helping me make a better choice :)
So far, had best results putting it on a rear arm(fron of the quad is occupied by noisy HD camera and even noiser RX antena mounted verticaly on camera mount, rear of the quad is occupied by vtx antenna), getting gps lock within 30 seconds after pluging in the battery. Sure, prop can hit it, but how often it does happen in case of long range rig? And if so you have much bigger problem than possibly destroyed 10usd gps module.
i've had issues in the past with frsky 2.4ghz telemetry keeping me from getting sats, it was noise from the rx itself, not the antennas. Thanks for this guide.
would it helps to 1) add aluminum foil as a shield between the gps and the battery cables (or carbon)? 2) use shielded connection cable in which you attach the shield to the ground pin on the FC (and leave the cable shield floating on the gps side to avoid ground loop)?
This is interesting.. I use the small non-magnetometer gps from matek and have it mounted on my rear arm of my source one 7in deadcat. I use an external high precision magnetometer mounted directly behind my fpv camera. I've never had a problem that way and always have a solid lock.

Do you know the GPS (BN-220)? I just can't find satellites. On the laptop in Betaflight 2-3 satellites and at the same time it shows 0 satellites in the OSD. I was outside in the garden .. Half an hour but no satellite ... nothing. The GPS has a clear view upwards: /
Thanks. We we were just having a discussion on the iNAV group about this very topic last night. I originally posted it, and mine is mounted in that area, but it's really close to the battery leads, running 6S. I guess I will have to design something from scratch to move it farther back.
That's correct. I have GPS in the back, but close to the battery leads, and it is really really hard to obtain lock. On my other quads, I have placed GPS on the arm, close enough to motors (and those are beasty motors) so bent propeller can't hit them. Works much better than GPS on the back, close to the battery leads :-)
@@MartinHapl on GPS antennas that don't have an compass that works fine, but there is too much interference for a compass, and is also too close to the carbon.
i sometimes think of rigging up something 3d printed between the two motors on the side like between no.4 and 3 or 2 and 1. then the compass/gps would off the side in the middle of nowhere.
Thank you Pawel, my question is I like the way you have vertically mounted the rx antenna, if you were using nano diversity rx, how would you mount the second antenna. Thanking you and possibly your viewers for any assistance. 👍
Careful a split type camera puts out a ton of noise and will affect the GPS if it not shielded. Even with the backpack I think it will affect the GPS when using backpacks.
Thanks for sharing the knowledge of placing GPS, but now I am considering to buy GPS BN-220 instead of BN-880, which one should i get for better signal and reliable?
@@MrStevegibb yes, I am considering the sensitive of them, they both use u8030 KT, but using different antenna 880 with active , and 220 with passive antenna.
Pawel, what GPS with magnetometer should I get for an Eachine hd quadcopter with a f722 mini flight controller and the DJI Air unit? What would work, must have I2C connector? What protocol to use in betaflight or iNav?
Hay pawel, im going to be using an external magnometer, does it haveto be mounted completely flat? Or will it not matter because i will calibrate it anyway?
Another great video!! I've noticed the arrow is pointing to the back of the quad. is it necessary any config to tell the position of the GPS to the FC? Many thanks
How to get started with inav mission control ? On selecting the inav mission control tab I can’t get any maps or relevant option to open a map. Though I have a matek gps installed. Please assist !
Pawel, can't inav navigate without a magnetometer on a multirotor? If not that should be easy to implement by just making the frame tilt to a fixed angle forward and then navigate as a fixed wing on GPS only.
I Wish they did this even if they disabled land and made it just loiter besides the way a drone flys with a mag on inav rth is very mechanical and jerky.
I have the matek m8q gps and it’s taking 15 minutes to 3d fix, any ideas on how to make that better. Instructions say 20 secs. Nervous that with waiting 15 minutes the dji air unit will over heat waiting for the fix.
If I cannot mount a GPS closer than 5 cm to the motor, and not anywhere near the camera or VTX, then I have no place to mount it. This makes small drones with GPS impossible. My drone is about half the size of yours.
Love your videos. Having trouble getting GPS to work with inav 2.5. Can you help me. I get a gps lock but no altitude in osd and rth and pos hold not working
Very informative! But I always wondered one thing: with magnetometer disabled in a FW, can we install the GPS receiver as close to the motor as we like, or could extreme proximity cause RF disruption? The motor pod of Bixler style pushers would be a convenient location if we could safely use it.
I have my BN-180 mounted 5mm from a motor on an arm. 20+ sats and much quicker to lock than when it was central. It is close enough to the motor to avoid prop strikes.
@@treesifpv3848 Interesting! But you acquire those sats before you even arm, right? Can you tell from your OSD whether you keep that lock while the motors run?
@@Videolinquency I hadn't thought of that - but yes, there would be no power to motors before arming. It does hold lock after arming. So it seems spacing from other electronics helps, and motors don't seem to be a problem. No magnetometer though, if I had one then Pawel's method at the back would be best. I had a bracket previously, but it was more exposed in crashes so I tried the arm. It is wrapped in insulation tape and wires routed out of the way of prop strike zone.
@@treesifpv3848 Thank you. That means I won't have to keep the GPS receivers as far from the motors as I have done before. But I still think we should leave an inch or two if we can - it would surprise me if a running motor did not emit at least some radio noise - though I gather from your reply that it can't be a lot. Come to think of it, brushed motors certainly did when I made my first FPV flights in the naughties. They tended to ruin the video if they got too hot.
The telemetry downlink is indeed close enough. But downlink is happening with low power and as long as antenna is not directly on the GPS it should have minimal impact
Hmmm.... Then I have to find a way to mount it on the back of my Tyro129, but then it will be below the VTX antenna wich is pointing backwards and up. Would that work?
I came to the same conclusion. Most of my GPS modules are mounted on a TPU printed part on the rear/backside. At least for the GPS signal, RX or VTX antennas seem to be no issue if there is a distance of 1-2 cm to the module. I also found that steel screws often interfere with the compass. Stainless steel seems to be no problem.
It actually seems to be the best place to get the antenna. I am going to switch to INAV with BF. Unfortunately, my FC does not have SDA / SCL pins for the magnetometer. Does anyone know about a GPS + Compass device which only uses the same UART? It is said that DJI NAZA can do it. Is there any other solution besides changing FC?
@@FPVUniversity I see, thank you for replying. Currently upgrading my Nazgul5 V2 with a GPS. I have a BN 220 and a HGLRC M80 Pro, and can't decide which one to put on. Any advantages of having compass on betaflight or just go with the BN220? with compass it would also probably have to be flat, not at an angle, right? saw somebody made a 3d print for a battery strap, but will most likely print something for the rear, as you suggested in the video. thank you for all these great videos, I watch you frequently. Learned alot from you for my Dart XL and glider INAV builds.
@@FPVUniversity Could the gps go below the video antenna? You mentioned moving the antenna down to make room on top, but Im thinking move the video antenna up and put the gps below it. bad idea?
Very bad advice. I checked it on myself. This positioning of the gps+magnetrometr at the back creates a lot of air resistance. Stick your palm out the window of the car driving at 100 km / h and you will understand. The problem manifests itself in pitch jerking at speed. For a long time I could not understand how to cope with the jerking problem, although the pids were calibrated to ideal using a pidanalizer. But I calibrated the pids at low speeds, so the "sail" in the form of a gps module did not make itself felt. Moved the module so that resistance was not created and now everything is fine)
Nice video, very useful! I was building a quad with a Baitan BN-180 and mounted it with TPU mount at the back. There are some pictures on my Google Drive drive.google.com/drive/folders/16S8bSjQwRBKSvgR_V_YIlZZ4HrHKWB6C?usp=sharing It works but unfortunately it takes ages to get the GPS fix.

When you mount the GPS with magnetometer on top of the HD cam, with some tin foil inbetween, would that work?
Tin foil will not shield magnetic field. It can shield from some of the RF noise as long as it's grounded
