M10 gps and Betaflight 4.5 are really amazing. @12:10 The faster GPS baud is CPU intensive. It's advised to use 57600 baud AND 4k pidloop (even for F7) per the "Betaflight 4.5 GPS Rescue" docs. If you want 8k8k then you have to use 2Hz which is 19200 baud. Great how-to.

You said the simplest thing, and it made it dawn on me, about putting the GPS on a USB 5 volt rail, especially when using HD. Never even thought to just plug into it at the field, and let that "warm" the GPS up, so the VTX is not running and over heating. I learned something today!!!

If you connect the GPS to a USB powered pad, it will sometimes interfere with BetaFlight firmware flashing. The iFlight F7s have this issue and it’s happened to me on IARTs I’ve been told it should be an issue on. It definitely happens on the one recxomended for GPS. Crossfire also has this issue. What has worked better for me is to use a flight controller with a built in put switch and use that to turn off the VTX for the first flight of the day until I get a fix. Your flight controller has this and also does not power the GPS from USB. This is much easier to deal with than plugging in USB for the first GPS fix.

@blueskyfpv 2 месяца назад

Thanks for the setup explanation. With the GPS, HDOP is "horizontal dissolution of position" . It shows how much you are drifting horizontally. Less is better. Roughly speaking a 1.6 HDOP means your quad will hover 'in place' within a 1.6m horizontal square.

About Galileo: It's the satellite navigation system of Europe. GPS is American made, then there is GLONASS (Russian) and BeiDou (Chinese). GPS, GLONASS, BeiDou and Galileo are the biggest/most well developed systems. General term for these is GNSS. Most GNSS receivers can work with three systems simultaneously.

As for the ground assistance, in north america it's safe to set it to WAAS because that's the only one available here. I highly highly suggest anyone using gps to have WAAS (or your local equivalent) enabled, because it takes the normal gps accuracy of 50 feet or so, and turns it into ~3 foot accurate with basically no downside. It's the same technology full scale aircraft use all the time to navigate to runways even in poor weather conditions.

@spartan3299 2 месяца назад

Or maybe try INAV. Also flies great Acro, and will raise to a preset altitude to clear the highest obstacles before making a beautiful landing at the takeoff point or a safer preset home point.But...good progress BF. Looks very useful.

@TurboThailand 2 месяца назад

BF will either raise to preset altitude OR a preset height ABOVE the highest altitude you have flown during that flight. Also, it lands perfectly smooth touchdown, I was impressed that one one landing one prop just tiny touched a leaf on a bush.... it immediately disarmed and dropped the remaining 2ft

On the previous betaflight update Me and Droner Boner had a DJI goggles and DJI remote on a 03 unit and unplugged the goggles it went from 2 feet from the ground and flew way out and flew back to crash behind us. Very scary BUT when you done it on a switch it worked perfectly. We only tried this out because mine done the same on a long range flight. I seen the goggles loose connection. It came back in and was doing random hovering stuff till it flew away. I had remote connection the whole time. It would not do anything at all I tried my GPS switch. I tried disarming and everything. It just flew away... I specifically done a GPS test 2 baseball fields away before I done the long range flight. It returned back perfectly on the switch. So of course I felt confident to do the flight.

JB - Did I miss the part where you performed the 4th and 5th step under the "setup" section? : - enable a Mode switch that will activate level mode - in the Failsafe tab, set your Level Mode channel to activate Level 1 when in Stage 1. This will slow the quad down and level it out in preparation for the rescue.

Galileo is a constellation of satellites (European) same as Gps(American), Glonass (Russian) Beidu etc… SBAS stands for Satelite based augmentation system, based on ground stations giving possible corrections to certain satellites being off time, transmitting it to a ref satellite (Wass is PN the Us, Egnos in Europe or Gagan India, etc..) to compute the correction signals, the SBAS geostationary satellites communicate with regional ground stations and this leads your system to use more satellites even if they are not perfectly synchronised : more satellites being used leads to a better position precision less than 2 meters in my case !

@AsgardStudios 2 месяца назад

I know we’ve come a long way in the FPV hobby and I appreciate all the things the devs do, given that this is a volunteer open source project. But I’m still surprised it’s this complicated to make return to home function, sort of. Also, the heading arrow should really just be taken out. If it doesn’t work reliably most of the time then it’s really a hindrance. I nearly lost a drone by relying on. My bad I know. Issues aside, I appreciate where we are and I love this hobby!

Thank you for the tutorial. ❤ Do you have any idea, why gps acquision is very poor on btfl4.5? Sometimes on bad cloudy day it might lock 7 sats. But sometimes, even on clear days, gps sits there with zero sats for 30mins, until the lipo runs out. Even with vtx turned off. I know, that I have set it up correctly. In inav I always get no less than 14 sats in 2mins. I have even shielded and grounded gps wires. Btlf is so poor with gps, even on 4.5 version.

@121sim 2 месяца назад

Some words on the CLI parameters GPS_RESCUE_VELOCITY_[PID] and GPS_RESCUE_VELOCITY_[PID] would have been good. They make all the difference of either letting you sit back and enjoy the auto-return or, when set incorrectly, giving you a heart-attack. Any pitch-jerking on return or throttle oscillations on the descent can be tuned away.

@bweber0204 2 месяца назад

Galileo is the name European Union satellite consolation with 24 operating satellites as a posed to the USA satellite consolation called Navstar. Also, with 24 operating satellites. So, with it on in betaflight, it gives you access to 48 satellites instead of 24. I'm not sure which ones do or don't, but the gps unit has to be able to receive the signal from the galileo satellites, or it won't work. HDOP stands for Horizotal Dilution Of Precision.

@flaparoundfpv8632 10 дней назад

The ascend rate and ground speed rate should be adjusted to something that matches a failsafe scenario. Default ground speed is 7.5 m/s. Should be around 30mph or 12m/s for a conservative 7" speed that gets you home but doesn't stress the battery (or do that repeated braking thing that you're seeing). I you're failsafing with a 7", you really want to baby the throttle and not ascend too fast, because chances are you're on top of a mountain, your battery is cold, and you really do not want any sag if you're trying to make it home. Set the ascent rate lower, down to 4-5 m/s instead of the default 7.5.

Does disarming reset the "maximum height during flight" value? Because if it does, then if you use "set homepoint once" you could fly home too low or something.

@JoshuaBardwell 2 месяца назад

That's a great question and I don't know the answer for sure. I would guess that it does, and each time you re-set the home point, you also re-set the max altitude. But it's a pure guess.

@@JoshuaBardwell I should add from my proper profile. Like you the engagement of RTH on 4.5 is much better. Accuracy is also incredible.. Last week in testing I put on a small signs shadow on the concrete, 3 flights 3 RTH and landed within 10cms each time :)

Hi guys! I found the reason and I'm on my way to fixing this pulsating / stepy behavior on my 3" and on my 3.5" cinewhoops: The solution to this is to tame down "P" and "D" parameters on the two GPS Rescue exclusive PID loops! Yes, there is a PID loop devoted exclusively to throttle management during GPS Rescue climb and descend and there is another PID Loop just for managing pitch + throttle for controlling velocity during GPS Rescue return to home flight. I learned two hard truths about those: 1/they are completely independent of regular Acro PID parameters and 2/BF defaults may be good for 5" and larger, heavier drones, but are terrible for smaller, lighter drones like 3" cinewhoops... I came down from the original (gps_rescue_throttle_p = 15; gps_rescue_throttle_i = 15; gps_rescue_throttle_d = 20) to the values I'm playing around now of gps_rescue_throttle_p = 10; gps_rescue_throttle_i = 10; gps_rescue_throttle_d = 8 and behavior is not quite perfect yet, but did improved a lot!

No. Patreon is the only service that has automated integration with Discord, as far as I know.

But the problem is that I have to manually manage your permissions on the server, and that doesn't scale. I suppose I could come up with a price for a one-time permanent lifetime access....

Still not getting .. what is better in 4.5

@JoshuaBardwell 2 месяца назад

Many bug fixes and performance improvements. For example, 4.4 did not auto configure m10 GPS so baud rate was not adjusted and update rate might be 1 Hz, resulting in jerky RTH flight.

@@JoshuaBardwell that jerkey rth with 4.4, I thought I made some mistake in setting Great if fixed, I will test soon

I regularly get 26 to 28 Sats using BF... Galileo is a European Sat so I'm guessing your Sat Rx can't even see it....best turn Galileo off IMO...My GPS is at the FRONT of the quad yours is in the WORST possible place...You know that right?...😮😮😳😏🇬🇧
