    Hi @mikhail-mayers Pictures here will be very useful. How are you powering the VOXL 2? Battery? Wall Adpater? Thanks!

    Dear Sir or Madam, We are currently evaluating navigation technologies for UAV and robotic platforms operating in GNSS-denied and contested environments. In particular, we are interested in solutions capable of operating without GPS/GNSS and, where possible, without relying on active radio-frequency communication links. Could you please provide information on your relevant products, including: GNSS-denied navigation capability; GPS-independent positioning; visual-inertial odometry, SLAM, inertial or terrain/map-based navigation capabilities; operation in radio-silent mode; integration options with UAV autopilots such as PX4, ArduPilot or proprietary flight controllers; technical specifications; pricing indication; delivery terms for Europe; export-control or end-user restrictions, if applicable. We would be grateful if you could also indicate the most appropriate contact person or department for further technical and commercial discussion. Kind regards, Andriy Lomakin

    @nl_vdi , if you log into developer.modalai.com, you will see the CAD models. the latest model we have is: D0012-4-V3-C28-M36-T7-K0-Starling2-Max-V3-20260317.step [image: 1781036132877-376bf0dd-494a-4bf1-8d92-1b2d91afb83d-image.png]

    @manzur Interesting, thank you for the information! Perhaps I was wrong about the default Network ID, I will take a note of that.

    Hi @Chad-Sweet it appears that I am on voxl-suite 0.2.0 as indicated above. However, if QGC reports that avoidance system is unavailable and the vehicle will not arm. If I run voxl-vision -s I can see the obstacle debug info on the terminal, also I set "en_voa": true, Any suggestions as to what I am doing wrong?

    @mvxl500 like Chad mentioned, typically with the PX4/QGC setup you have to power cycle PX4 after binding: From: https://docs.modalai.com/configure-rc-radio/ [image: 1621870241358-569470cd-1d23-44ba-8696-ab557b906e80-image.png]

    TBC is the translation from IMU to camera, OMBC is the rotation You can see 2D and 3D drawings on the datasheets page which should help you make the measurements https://docs.modalai.com/voxl-datasheet-functional-description/ Start by trying to recreate the known sets on the Flight Deck, and then make adjustments from there.

    @PawelJ Maybe. I couldn't test VOA and apriltag function with version 0.3.4.

    We have the same issue here with the Microhard pairing as posted in this https://forum.modalai.com/topic/251/issue-in-microhard-paring-with-slave-unit. We also tried to follow the instruction but its not paring.

    @Alfonso-Ponce You can disable the WiFi (ifconfig wlan0 down) so that LTE is your only connection. Then try to ping something like www.modalai.com and see if that works. If so, then the LTE connection is up properly.

    @Voxlady Thank you! In the end I was finally able to understand better how the VOXL shell and the Docker image/container were working together. I was able to mount the volume just like they recommended and I could send my .py files and execute them.

  • LTE concurrent with Microhard

    It is possible to run concurrent LTE and Microhard connections on VOXL. This can be accomplished using a combination of the two modems, either with an add-on LTE modem and a standalone Microhard modem plugged in to the add-on or an add-on Microhard modem with a standalone LTE modem plugged in to the add-on. In order for both networks to start correctly, the LTE network will need to be brought up first, then the Microhard network. This can be set up easily by creating a custom startup service. The LTE network will use the wwan0 network interface while the Microhard network will use the eth0 network interface.

    @Alfonso-Ponce We don't have any recommendations on how to create such a mobile application. However, whatever path you choose, you will most likely need the app to be sending Mavlink packets to the drone to carry out the instructions. Also, QGroundControl can be run as a mobile app and it is open source so you could look to that as an example.

    The only lower bound I've seen is 20cm here: https://gitlab.com/voxl-public/modal-pipe-architecture/voxl-vision-px4/-/blob/master/src/voa_manager.c#L165 So I'm still puzzled. If you debug stereo, what kind of data are you seeing? https://docs.modalai.com/voxl-vision-px4-collision-prevention/#debug-tools

    You could also convert the script into a Windows batch file or some other Windows scripting language. But there are Debian specific things in the script file that you would need to convert to the Windows alternative. For example, there are package management commands (apt) that would need to be changed into something for Windows and you would need to use the Windows version of QEMU. This could be a challenging task!

    A lot of effort goes in to supporting a new modem on a companion computer. The kernel needs to be modified, drivers need to be developed. We sell specific accessories that we put that effort in to so they can work with VOXL. Without knowing what type of modem you are trying to connect, it is difficult to suggest where to begin. Some things that might help: What type of modem is it? What interface are you connecting with? USB, serial or Ethernet? Does it have an available Linux driver? If it is USB, and you type 'lsusb', does it appear?

    The short answer is yes, the long answer is that it is probably a decent amount of work. PX4 1.9 builds and runs for this platform, but may not fly. With that build, you need UART based ESCs like we have here: https://modalai.com/esc Mid-PX4 1.10 development c++14 was introduced. The SLPI compiler does not support c++14. IMO it would be fairly straight-forward to either comment out that code (it's for simulation), or just use boost to fix the issue. We just haven't done that or put much effort into it. You can take a look here: branch https://github.com/PX4/Firmware/commits/excelsior_1.9 Build the firmware with "make atlflight_excelsior_default" to build the posix side and "make atlflight_execelsior_qurt-default"

    No, those are PCIe interfaced, so form factor wouldn't plug in. The "WP" series is the correct form factor, we've tested against 7610 and 7607, but there are more listed: https://source.sierrawireless.com/devices/wp-series/wp7610/
