My apologies if this is a rudimentary question... How often does a Pixhawk broadcast telemetry data? I am working on configuring a Pixhawk in a high altitude balloon for antenna tracking. I'm not very educated in the Pixhawk, so am not sure where to look for the answer. I'm hoping to avoid it blasting a continuous stream to avoid interference with other electronics on board.

HI All
Hope this is the right area!
I am having trouble setting the low value for the radio failsafe, I've kind of worked around it but was wondering if there's a better way. I'm using the FlySky FS-I6 TX flashed with the 10 channel firmware, and a FS-IA10B RX.
Setting the failsafe value on the TX only goes down to 100% - so when the TX is turned off, the RX goes into failsafe mode and drops the throttle to the -100% value, 1000, which isn't enough to trigger the failsafe (set at 975). It just looks like you've throttled down. So what I did on the TX, was slightly raise the lowest value on the throttle curve by about 2%, which means that when the throttle is in the lowest position the PWM value comes across as around 1020, then recalibrated in Mission Planner. When the TX is turned off, the value then drops to 1000 and I can set the low trigger value to 1004 which then triggers the failsafe.
This all seems a bit kludgy, is there a better way, or is it just a limitiation of my radio setup?Thanks
Bill

Hi,
I am having some trouble setting 3DR 900mhz sik radios for one of my small testbed copters, I haven't used 3DR radios much before, mostly rfd and dragonlink.
The radio connected to the copter (Pixhawk Mini) starts flashing green slowly ~0.5Hz and red rapidly ~2Hz (not the send/receive type of flashes) and it doesn't communicate to PC side. Radios can be switched places, with same result, copter side gives the flashes. Sometimes, however it briefly works normally and manages to connect, but no more than 1 minute, then resumes to the flashes. Problem started after I have updated the firmware from the initial one those radios had installed since 2013 I guess, when I first got them, to 1.9. I have also tried 1.7 with exact same results.
Another change I have made is increasing cable lenght on copter side, to about 40cm, could this be a part of the issue?
Thanks,
Anton

Hi,
I've had my APM2.8 controller and F450 flying 'ok'. Did a basic autonomous mission and it all worked correctly.
I was testing the battery fail safe when it didn't have enough power to correctly land and had one crash. I've since repaired the damage and reset the firmware + parameters.
I've now reconfigured everything and switched my transmitter to S-FHSS (figured it was a good time).Currently the done can't hold it's altitude very well (AltHold and Loiter). I've attached a log of a short flight where i go into altitude hold (and at the end turn of my radio to test radio-fail safe as well). You can see that my throttle (RC3) is nicely at 1500 while the drone goes up and down a few meters (Alt and BarAlt in CTUN).
Is there any hint in the attached log that could explain why this happens?
The only thing i can think of is that i did the motor/compass comensation slightly differnet this time, but i don't know to confirm that this might be the issue.Thanks!2017-06-25 22-39-19.bin (511.0 KB)

Hello,
How do I add servos to control? For example, I am using AP_MotorsCoax. In AP_MotorsCoax.h I see
SRV_Channel *_servo1; SRV_Channel *_servo2; SRV_Channel *_servo3; SRV_Channel *_servo4;Do I just add another line with *servo5? Do I need to modify anything elsewhere except for APMotorsCoax.h and also adding servo5 in APMotorsCoax.cpp? What would be the pins for _servo5? I tried to add _servo5, but it kept giving an error. Therefore, I want to ask if I need to add lines elsewhere.
Thanks in advance

Hi. I'm trying to work out how the AP on the Edison is setup within the APSync build.
i need to change this to not be a AP rather for the Edison to connect to an AP.I thought Hostapd and dhcp server were used but I see no config files to edit.
Could somebody please tell me how this is setup.
Best Regards

Hi
I want to receive ESTIMATOR_STATUS STATUS_REPORT messages from the copter. By default, it is sent from the drone so I tried to request it using mavlink_msg_data_stream_pack but I am not receive it even after requesting it.
The request command I send :
mavlink_msg_data_stream_pack(200,20 0, msg, MAVLINK_MSG_ID_ESTIMATOR_STATUS, 4, 1);mavlink_msg_data_stream_pack(200,200, msg., MAVLINK_MSG_ID_EKF_STATUS_REPORT, 4, 1);I even tried to set the rate to 100 but the same result.

I have finished my AT. Here is my setup:
pixhawk + extern compas, GPS
standard 90deg servo for pitch
continuous servo for pan/yaw
433MHz TxRx link for telemetryPixhawk is loaded with AT sw of version 0.8.
Compass and accels are calibrated.The probrem:
When AT is powered it stays in neutral position, so far OK. After it gets connection to vehicle yaw servo doesn't move
but pitch points stright up to the sky quickly. In this position tracker stands forever. It doesn't move in any direction - neither yaw nor pitch. Regardles the vehicle moves around the AT, it doesn't move.Will look tomorrow morning if there are some logs, would it help? Even param file I can provide.
Any suggestions?

After a bit of research, it appears that you folks are probably the most conversant to give advice for a project that's a bit out of the ordinary.
I fly high powered rockets and we go for speed and altitude with these launches. Our best is altitude of 75,000 feet with a max speed of mach 2.2. This was a three stage rocket. Recovery is by parachute; first a small drogue at high altitude (apogee) and then a main chute at low altitude (1000 feet). The problem is that we have no control over where the rocket lands. We've found stages of rockets as close as 1/2 mile and as far away as 12 miles.
We want to deploy a parafoil at reasonable altitude for each stage to fly the rocket (fin can, nosecone, body tubes) back to the launch point (or a designated recovery point). We have the mechanical design mostly figured out; the challenge being that we have to get the chute out without tearing it or the rocket apart since we cannot always guarantee low velocity deployment (but that's figured out).
Our parafoil design is 12 sq ft to recover about a 12 lb load, and the control lines require about a 5 lb pull. To get the required torque we will need to gear down motors, which leads to slower response than you'd find with a plane. I don't have much experience with the guts of autopilots.
Several questions:
1. Can Ardupilot be configured for this sort of control given the slow control and directional response?
2. How can Ardupilot be set up as a glider toward a pre-designated landing site?
3. What sensors are required in addition to the standard package if we want to compensate for wind deviation to get a straight line back to the landing point? I would seem we need either forward airspeed or a precise compass to figure out the wind vector to allow compensation.Thanks in advance for thinking about this. Happy to address this to a different category if there's something more appropriate.

Hi Everybody !
I had a problem last day with a steadidrone MAVRIK X8 that crashed by itself into loiter mode. It was a bit windy but not too much so I assumed that it should not have been a problem for that drone. I would like to understand the reasons of this failure before flying again.
After a while in loiter Mode, the drone began to rock from the left to the right, more and more, then it crashed on the ground.
This drone is composed of a 3DR Pixhawk, with a 3DR GPS
Here are the log Datas : https://apps.etre.ensam.eu/FileZ/90zmx0Thank you very much for your answers

Maverick 1.1.0 'Ooh pretty pictures' Release
The latest Maverick release adds a web based mavlink/dataflash log analysis tool.
- Drop any bin or text dataflash log file into ~/data/mavlink/inbox and it will be automatically picked up and imported into a nanosecond resolution time-series database (InfluxDB), and a set of links added to the web dashboard.
- Use mavlink-router as your mavlink proxy, and set LOG_BACKEND_TYPE to 3 in your flight controller (or SITL) firmware. This automatically saves dataflash bin logs into ~/data/mavlink/fc (or ~/data/mavlink/sitl), and as soon as you disarm the logfile will be automatically imported into InfluxDB and a set of links added to the web dashboard.
- A wide variety of system metrics are automatically collected (using collectd) and imported into InfluxDB, and are available in realtime in the System Dashboard, including power consumption and thermal status for Joule modules.
- Realtime mavlink graphs will come soon to a browser near you
- Best of breed opensource components - Collectd, InfluxDB, Grafana
- Preset dashboards for Flight Data and EKF2 graph sets. EKF3 to follow.
- Interactive graphs, zoom in and out, linked graphs, alerts
- In the future, rich custom analysis pages using statistical engines will be included
As always with Maverick, to update a previous installation just do:
maverick self-update maverick configureTo download and install, please see the documentation:

Hi guys
I have a massive problem, I have a dropix with copter 3.4.6 and since I installed a servo gimbal, my octo wont arm because the the inconsistent Accelerometers.
the servo gimbal is connected on my FC, so it will power on only after initial calibration, but I think that might be the cause of my trouble or it's a problem with my FC
Is there any way to delay to power on my gimbal or power it when I arm / pre-arm my drone?
Last week it happened to me so I did another calibration and it work perfectly even with connecting - disconnecting my drone
