You can trick the GPS by plugging in a usb powerbank into the flight controller. This way the vtx doesn’t transmit and gps signal is found much quicker, like 1 minute cold start without up to date satellite data after being turned off for days. Once it has found satellites it will only do hot starts when flying normally and find sats in seconds without powerbank. At the field I usually plug in a powerbank first and then set up my transmitter and goggles. When I am ready to fly I got enough satellites data for the day. This only works if you solder the gps to a 5v pad that is powered from usb of course.
Cheers Wayne, thinking of getting one as i was learning to fly acro with my 2.5" quad and the wind took it . 40 mins later I luckily found it 2 fields away.
Well done for finding - as keen as I am on battery backed buzzers and things, I rarely put these in smaller quads - but it goes to show what can happen when things don't quite go as planned. This is nice and light, so will fit on a small quad quite well. Those coords will give you a decent chance of finding it's last position as well
I use the same HGLRC GPS on my drone, and I can confirm with a warm restart you get 8+ satellites fixed much faster. Around 1 min in my garden, and even less in open field. I'm using Ublox protocol and autoconfig for the others param. I tried GPS rescue several time, with a BN880 on a 7 inch, and most of the time it has been working, till it doesn't and I lost the video. I provoqued a failsafe immediately, and find the last accurate gps coord on my CRSF and on my last DVR frames received. They were pretty closed ... I took my car and drove to the point quiet anxious to find my drone back. And here he vas, flashing and beeping in the middle of a laboured field, just waiting for me ... lol...at only a few meters of the gps coordinates. I was so happy, to get it back. Without GPS not sure at all I'll be able to find it back, cause much far away of where I was thinking. For me so far, Gps rescue is not totally safe at all, but it's so good to have gps coordinates in case of problem, that I'm starting putting a GPS on all my 5-7 inch quads. Look forward to see the results of your experiments, once out of covid. Thank you for all your work and sharing results
My rescue mode testing in the past has worked pretty well, but really it's one thing out of many that you should be thinking about to get your quad back - and it certainly shouldn't be relied on. But as you found, using a DVR and getting the last good GPS coordinate works pretty well too. That and a beeper - perfect.
I know that GPS modules with the ceramic antenna have to have the antenna pointed upwards, but does it matter what the side orientation is (i.e. does a specific side have to point to the front of the quad)?
Whilst it doesn't appear to, if you watch the follow up video you will see that the whilst the initial acquisition of sats is very slow, the next battery is very quick. So it either has a battery that's very well hidden, or perhaps it has some capacitance that keeps the sats in memory. Either way, a hot start is nice and quick
darn i try to install my gps, everything is welded well, gps light is ON but it doesnt show it on the upper tab and when i go on GPS tab on left side it cant be found...I have SucceX E -F4 Stack I hope this GPS is compatible :D
There's a few stages to this. First off, make sure it's setup in the ports tab and after you save/reboot go to the configuration tab and activate the part where it says "Use GPS for navigation" once saved and rebooted and you enable the expert mode in betaflight this will give you the GPS option on the left hand side
I've used the Beitan ones and they've been ok. What I do notice (just to see if it fits your situation) is that the GPS signal can get wiped out by FrSky telemetry data, so the positioning of your GPS is more important if you are using that type of rx
I know it was a cheeky comment, but you'd be surprised the number of people asking legitimently about fitting GPS's to tiny quads. WHy you'd need it on something that'll fly for about 3 minutes quite slowly... I don't know :D
I am able to lose control of my whoop in less then 10 seconds. So when it keeps flying away for another 3 minutes, a GPS comes in very handy to find it ... 🤓
iNav still requires a compass as well though no ? There is no RTH in Betaflight, it's RTHAC (return home and crash) the idea being that you take control back before it gets all the way back :D
@@CurryKitten Yes, compass..I now have 2 GPS Quads with iNAV...I just want you to try iNAV on a quad...because I'm sure others out there can't wean themselves off Betaflight...Besides, I'm interested to hear your thoughts on it....🤔🤔🤔😳😷😷😷
If you can't go into pit mode, then you might want to think about something like the GPS mate ruclips.net/video/G9SVh4PaWWg/видео.html&ab_channel=CurryKitten Depending on how your FC works (i.e will it power the GPS from USB) you could also just plug in a USB power supply to the FC and wait for the right lights on the GPS to flash indicating a lock before you plug in the lipo

So glad to see you installed the antenna right side up. I can't count the number of times I've seen them mounted wrong even on store pages...
I should have pointed that out - it does confuse many a person who assume that the writing is the bit that you should see :D
Thank you for this video! finishing my first build with this GPS unit and your video is very helpful!
Glad it helped!
Thanks for covering the section about acquiring the sats. Tremendous Help as always 👊🏻

I have a couple of ESC's by HGLRC which im pleased with but the HGLRC Aurora fpv cam by them is a bloody good camera, by far the best cam i own :)
I think there stuff is top notch - good all round company IMO
@@CurryKitten yeah, ive been very happy with their products and wouldn't think twice about buying anything from them as im confident in the quality :)
Great vid...love the Batman I have one my first quad
It's a cracking quad isn't it. It lives on my wall so i can always grab it and fly :)
I would have liked to see how it is installed I have the hglrc sector 132 using a helio board
I know that GPS modules with the ceramic antenna have to have the antenna pointed upwards, but does it matter what the side orientation is (i.e. does a specific side have to point to the front of the quad)?
Not - as long as you have the antenna pointing upwards you are all good. The direction matters if it's also a compass, but if not, then no worries
Does this GPS have no battery for hot start..?

I've 3 Beitan GPS's here and no one is getting a fix. I haven't had problems of getting a fix with a HGLRC GPS yet.

sooo can this work on a whoop
If you have a spare UART... But u might choose a BN180 because of the weight (BN180 ~ 5g, HGLRC ~10g).

It's the same..
..... as what ?

They look physically different to me - quite possibly the same module though
