Hi everyone, I am trying to use sik radio with navio2 and raspberry pi to communicate with my quadcopter from a control station but it somehow interferes with the GPS signal. What can I do to avoid this interference? already try to locate the radio sik as far as possible from the GPS without any improvement

Hi,
Can any one let me know how to use Reach RS+ for taking the static GCP’s in the field …I am not interested in RTK mode …
Your valuable suggestion shall be much appreciated.

I’m not sure what happened, but my navio no longer connects to wifi and when I hooked the pi to a screen, it shows EXT4 fs errors. So, I want to try it with a fresh image. Where is the file that has my parameters and settings stored? I’d rather not go through all the calibrations again. I can’t just connect to it and save them.
update. In the depths of the ext4 partition, the file with all the parameters is Arducopter.stg Or arduplane or whatever you’re using. It won’t load into mission/apmplanner like a regular param file, it has to be copied manually to the freshly created SD card.

After reading a post in the forums here I heard about a very intuitive software called EZSurv.
I went to their website and signed up for a week trial.
Stephanie sent me a product key to download the software,
and literally in a few clicks I had my base and rover data processed.
One more click, and I had a tag file for my images.
Turns out the format of my tag file wasnt in the correct system for Pix4d.
One more click and my data was converted.Zero screwing around or starting over. She walked me through the features of the software and I have to admit, it is extremely user friendly and im very impressed.
If your tired of messing around with RTKLIB, swearing at your computer, and want an easy to use very intuitive software that will locate a CORS station for you,
Hit up EZSurv. NOW!

Hi all, as you may be aware from my recent posts, I am working with EZSurv on post processing and am generally very happy.
I need to set up a custom antenna profile which requires some settings which I cannot find on here or via searches, can someone help or perhaps point me in the right direction.

Hi,
I’m using ardupilot on Navio2 along with ROS, with the aim of mapping environmental data using an additional sensor. I’m wondering if there is a way to connect my sensor to a UART directly on the raspberry pi, rather than the Navio2? My plan is to write a program that will take the position estimate from ardupilot through ROS, read the environmental sensor data from a serial port on the pi (at 921600 baud), do some manipulation, and write it to a datafile.
thank you

I posted a while ago about problems getting the OrangeRX DRX R618XL receiver working.
After more investigation, it turns out that the OrangeRX receiver does work, but only for a short period if time (20-30 seconds), before getting “choppy” (working intermittently), and then cutting out completely. The only way to recover is to unplug/replug the receiver to power cycle it, at which point the same thing happens. This seems to happen faster/more if I am moving the sticks (and controlling servos) rather than leaving them down/neutral. It seem to take longer if the rover is not armed (servos not moving/drawing power), but does happen after several minutes.
I realized this after trying a different receiver - Power Up RD810 - which works as expected (with the small annoyance of not persisting in PPM mode between shutdown/restart, requiring manual configuration every time.)
With the RD810, I can see the Radio Channels changing as expected andcat /sys/kernel/rcio/rcin/ch2is ~1102 with the throttle low and ~1974 high. Servos also move as expected. This leads me to believe the Navio2 hardware, software, and setup (servo power etc.) are all fine. (In the short times when the OrangeRX receiver is working, it’s values are ~1053 and ~1893 respectively.)My best theories for why the OrangeRX would behave like this are 1) Overheating (it does feel rather warm to touch) 2) Timing issue with the ppm framerate getting our of sync 3) A bug in handling 6-ch frames vs. 8-channels 4) Some functionality of the receiver where it stops outputting if it receives the same inputs for too long.
Given the above behavior of the issue occurring faster when the servos are moving, yet the nothing going wrong for extended periods of time with the RD810 receiver moving the servos, I am led to believe the problem is either with the OrangeRX receiver itself, or some complex interaction with the receiver and the servo busses. If so, there’s not much that can be done here, other than document it so others can be aware and not waste their time debugging.Other Info:
-ArduRover 3.3
-Navio2
-Spektrum DX6i transmitter
-Servo rail draws 0.4A @ 6V
-Testing with two micro-sized hobby servos on outputs 1 and 3 which draw <0.25A combined.

Hi, I have a problem with one of my RS+ units, where it simply just won’t see any wifi’s.
I have 2 units. One works perfectly (one that recently replaced due to another an seemingly unrelated WiFi issues), but the other just won’t see or connect to any WiFi. The list of wifi’s is simply empty, but on the other unit I see my WiFi’s and the neighbors just fine.Here is what I have tried so far, all without any success:
- reflashing the unit (2.14).
- checking all password
- connecting to a auto-switching 5g/2.4g network
- connecting “pure” 2.4 and 5g networks.
-checked all passwords for the WiFi’s.- connecting to my phone WiFi hotspot:
It seems like it is trying to connect, but for some unknown reason never succeeds. On my iPhone hotspot, the blue hotspot comes up for 1-2 seconds while the unit tries to connect, and disappears again.
What to do?

Hi there,
I’m aware that practical L1 baselines for RTK are limited to around 10 km, but i’m intrested if this increases if using a VRS NTRIP service which creates a virtual reference station by interpolating data from a network of reference stations.
I’m a user of Croatia’s national CROPOS positioning service which is based on a network of refernce stations spaced about 50 km from eachother. Map of reference stations can be seen here. The system produces a VRS on the site of the survey so baseline registered by ReachView is always just a few meters.My first question would be if somebody has an idea what would be a workable distance from one of the reference stations in this setup? I have achieved good results up to 15 km away from CROPOS reference station but i’m wondering about going further than that. I have an assigment in a few days which will be right in the middle of the two stations, about 25 km from each of them. Is this viable enough to achieve RTK fix?
Second question is regarding the best procedure for PPS surveys conducted with the same corrections source. As a CROPOS user i have access to historical RINEX logs for the whole system (paid by the minute of data). But also, if i turn on the NTRIP corrections in the field ReachRS records the VRS corrections while i work, which is actually cheaper and easier way to get to that data. Can i just happily use the Reach base corrections log with emlid RTKlib or is there any significant advantage in accessing the raw RS data from CROPOS records and doing my own interpolation by methods described by @r.pazus and @TB_RTK here and here?
Thanks in advance for all thoughts on the subject!

Hi
What could be correct pinout to connect Reach GNSS module to new Pixhawk4? In https://docs.emlid.com/reach/ardupilot-integration/ description reference made to Serial 4/5, however new Pixhawk 4 doesn’t have such a port https://docs.px4.io/en/flight_controller/pixhawk4.html . Any help?
Thank you!

Hello guys.
For all of you who want to stream fpv using an actioncam instead of the raspicam, Yes it is possible and I will show you that it is.
If you Google Auvidea B101 HDMI to CSI2 bridge. You can use any action cam with an HDMI and use that. So no more fragile raspicam with gello.
Here is a video and screen shot. The video was from the first flight after building my new quad. It was very windy with strong gusts so a bit shaky but you will notice almost no gello. The action cam is mounted with a strap and gel and you will so almost no gello.
Will be fitting my gimbal after some tuning.

I was wondering if there could be to possibility to edit project names and comments once a project has been created. I know you can edit the points names and such if it has been created but, when someone accidentally names the same project the same name and you drove 1800 miles to collect the data, it would be nice to be able to edit the name to actually be the correct research plot. Kinda trivial but would be nice. Also would be nice to be able to go back an add comments after the fact, simple notes about the layouts of the project. Maybe this already exists but I couldn’t find it or any docs on it.

Hi,
I’ve run through the install process for firmware reflashing, for Reach/Reach RS - for our Reach RTK & Reach RS. I’m wondering if the Intel Edison driver is OS specific? When I attempt to run it, a terminal program briefly flashes open, but that’s it. Or is this standard?
Thanks,
Liam

Did my first test mission with PPK yesterday… didn’t yield the results I was hoping for, so maybe you gurus can help a brother out here
I have a Matrice 600 with Sony A6000 camera, fitted with an Emlid hotshoe adapter and Reach M+ of course. I downloaded RINEX data from the national Dutch CORS network and used that in RTKPOST. PPK went fine, with just a few “orange dots” (I used the settings as described in the docs section)I also placed 4 GCPs as checkpoints, which I measured with my Reach RS (also fed by CORS correction data of course). This is how the captures look like in Pix4D:
I tried a 10 degree camera angle for this run… maybe that was a mistake, as this is the quality report:
Not the accuracy I was looking for… thoughts?
Oh… also… there were 201 initial pictures, but 221 recorded trigger events. It should have recorded every odd-numbered second in this case (camera is self-triggering via the time lapse app, every 2 seconds), but there were 20 faulty records, on even-numbered seconds. I removed these before geotagging the pictures.

Hi
I am currently working in Africa and will soon do survey flights 30-40 km away from the ground station which is too far for a PPK solution.
I would like to know if it’s possible to connect a trimble RTX GNSS receiver or similar to your Reach M+ system, the goal is to get with a satellite subscription like the Rangepoint RTX a constant accuracy of 50cm or less
Thanks
Benjamin

I have broken Intel Edison on one of Emlid Reach RTK modules, which I use. I have already tested it by replacing with Edison from functioning module (so I am 100% sure that I need replacement). As I understand - I can replace one from Emlid module with any other Edison bought from ebay, for example? There is no revisions, different versions and etc.? Also, can I buy just compute module (without any kit), connect it with Reach RTK board and flash it with Emlid’s firmware? Are there any nuances, which I do not realize?
