Is there a practical difference between cheap, less than $10 BN-180 GPS/GNSS receiver and more than 4 times as expensive Matek M8Q-5883. And I'm not even counting the $60 M9N and similar. Some say there is no difference, I state that there is. Here are the results of GPS receiver tests I execute a few months back where I tested lock acquisition time and HDOP of different receivers: BN-180, BN-220, BN-880, Matek SAM-M8Q, and Matek M8Q-5883. Enjoy.

Really interesting topic Pavel, thank you very much for this! Do you think it might be possible to have a follow-up concentrating on the ability to cope with interference from for example cheap hd cameras and the ability to recover from something like that in a "noisy" environment? Perhaps one or the other gps sensor might react very differently to EM noise...

@thirtythreeeyes8624
@thirtythreeeyes8624 2 роки тому
I've never noticed a huge difference using vs not using ground assist but, I think this will be highly dependent on where you are flying. I'm only really flying gps rigs in the middle of nowhere or in the mountains. Maybe in really noisy RF while also being closer to the towers there would be a noticeable difference but, I think it provides a less accurate vertical accuracy probably because of multipathing.

@blair.nichols
@blair.nichols 2 роки тому
Id want to see this test done with the same setup used for each GPS, a regulated power supply and a fixed(exact) position for each test. I like the idea but feel there are still too many vairables to get concise results. I also think multiple locations should have been used to rule out any changes. However, with that said I am fairly sure results would not differ too much.

the M8Q modules are also FAR LESS sensitive to outside interference, if the receiver is close to a motor, VTX, or a bad/cheap camera ... good luck getting a fix at all. the M8Q has no problems with his. also shielded cables are not really required as it just knows what is what. also i can confirm that the BN receivers do "Cold start" far more often that the Mateek ones do, for the 180 1+ hour is already enough to make it cold start on a 220 about 3 hours. the Matek does hot-start even after 6 or 7 hours. (not as fast but MUCH faster than actual cold starting)

Thanks for the video. You've been my go-to guy for learning how to install GPS on my 5" quad. Question: Does anyone using 5" quads on Betaflight utilize the compass component that many of these modules come with? No matter where I put the module on my 5" quad, I cannot seem to get accurate headings. I've fiddled around with the magnetometer's alignment in BF, put the module on a small stalk, made sure to calibrate the module when there's no metal around, etc. The one thing I haven't done is actually fly with it yet, but I'm assuming that if the compass doesn't work well on the ground, it won't in the air either.
@FPVUniversity
@FPVUniversity Рік тому
Betaflight does not use mag. You would need INAV to have position and heading hold
@AEMBowers
@AEMBowers Рік тому
@@FPVUniversity That's interesting. Then why does BF have a magnetometer icon on setup page, an option to turn the mag on and off, a mag alignment drop-down, a compass on the setup page that shows heading (which does change when I change configurations for the mag), a mag calibration option, etc? Why do you otherwise say that BF "does not use mag"? All I want is to see a heading arrow in my OSD as well as provide extra information to make GPS Rescue more accurate (many online have said a compass will allow for this)--I do realize that I cannot have position hold, RTH, etc, unless I use INAV. Here is a post from SnowLeopardFPV on the IntoFPV forum: "Unless you are using INAV or Arducopter then a magnetometer is pretty useless anyway. All you can do is display the your compass heading in the OSD of your goggles (unless you are using the DJI FPV System in which case you can't because they don't support the compass OSD elements). That is all. It can't be used for GPS Rescue or anything else in Betaflight." I will be using the DJI digital FPV system. Can someone confirm that I am out of luck in being able to get compass information under my circumstances (i.e., using BF and DJI digi goggles), even if I do manage to get my compass properly calibrated? It's confusing, because I've read a bunch of conflicting info about using a mag with Betaflight. No one seems to know the full truth.

@bambitakesflight7345 Рік тому
Hello Pavel, I'm not sure if you are aware but you can update and change the firmware on the GPS itself, this includes modifications for hot/cold start. Also once GPS has gained satelite data it will usually boot up a lot quicker and more reliably within that 24 hour period.

I got very similar results recently. I put an m8q-5883 on a flywoo hexplorer and a Bn-880 into a rover, both running iNav. Favourable results with both but the 880 is pretty big. With the m8q my RTH landings with the hex are very accurate. Never more than 30cm from the home point. (iNav 3.0) With the 880 I get 3D fix almost instantly and I'm running a DJI air unit in the rover with no problems to the GPS. (10cm separation between AU and GPS) a

Hi @willsintheair thanks for sharing your experiences! I plan to install a m8q-5883 on my Flywoo Explorer in order to be able to run it on INAV. Where did you mount this GPS unit on your Hexplorer? Did you use the original GPS mount in the back of the quad, or did you put it on a mast? I am wondering about the required distance between the Compass and the other electronics. Could you share your experiences on that topic? :)

So.. did you actually mention the test conditions anywhere in the video? I couldn't find it. I hope you did the test outside, otherwise it's not of much use.. Also measuring standard deviation of the 3D fix would be a better metric than the self-reported HDoP/VDoP. PS. Have zero issues with BN-220, suspect anything else might be overkill unless you need GPS position hold on multirotors or do Arducopter missions..

@CesiumSalami
@CesiumSalami 2 роки тому
I always suspected my Mateks were more accurate. My BN220s seem to lock on min sats more quickly and reliably, which is strange. every once and a while my Mateks take a really long time (even under similar mounting) and often the bn220 schools the Mateks on hot start. Fortunately I'm only using these for BF GPS rescue which sets a pretty low bar for needs / accuracy. Also prefer being able to set the 10hz update rate in ucenter and saving there as BF doesn't support UBLOX7 yet and that's not really possible (practically) with the two Mateks shown here.

@CesiumSalami
@CesiumSalami 2 роки тому
@@Simofly yep, both are capable of 10hz. Just depends on the firmware you use. For inav i think the ublox7 protocol sets them to 10hz. For BF you’d have to do a very tiny amount of custom code. But with the BN220 (and other gps units with flash space) you can set everything in ucenter and turn off any configuration commands sent by inav/bf.

My fiancee just overheard the intro. She asked what Pawel's OnlyFans access costs? Outstanding comparo, I hope that one day you'll have data for the M9N series to compare with these. It seems to me, most times I'm shopping for a GPS sensor, the BN-220 and M9N are the most prevalent and available. I haven't had great luck with either, usually waiting 5 minutes or more for a cold-start lock.
