@stephendade hi stephendade，Hello, after reading many of your posts, I greatly admire your talent in operating systems, especially non WINDOWS operating systems. Please accept my admiration.
I have a tricky problem now. I have a CUAV 7NAO raspberry 4B and an Intel T265 camera. I followed the prompts on WIKI during non GPS navigation, but it is RPI3 on WIKI and the image cannot be used. After many twists and turns, I finally installed Rpanion Server on the 4B I am using. At least I can manage the network and achieve communication between PI4B and the flight controller. However, the T265 camera and Raspberry Pi cannot run no matter how hard I try. I really don’t have operating system experience other than WINDOWS. The Rpanion Server version I am using is 0.10. Can you help me analyze it or provide a specific PI4 to run T265? Camera tutorial, thank you very much!
Why are you using T265? for Non-GPS position?
Here is something about T265 non-GPS position, which need ROS on Rpi.
if i can using Rpanion server ? I think it’s tiny and quickly.
except for T265 ,any good choice fofor NON-gps position ?
There are quite a lot of ways for Non-GPS position. I think it’s worth taking a moment to look at it.

Right now, I’m interested in A small VIO system using raspberry pi and arducam ov9281
As Rpanion is designed for:
https://www.docs.rpanion.com/software/rpanion-server
- Flight Controller telemetry forwarding
- Network control - configurable Wifi and Ethernet
- Video streaming
- Telemetry log management
- NTRIP streaming to flight controller
If you are trying Non-GPS position, then I think you should try to follow the link of Ardupilot Non-GPS navigation page.
@lida2003 the non-gps navigation page i have readed,but the page is about pi3b, i just use pi4b ,i tryed for 3days ,not worked …if you can help me writing a wiki for pi4b with rpanion-server how to using T265?
Did you check Intel RealSense T265 — Copter documentation
And I think it should be Linux+ librealsense+ ROS+ python ---- Ardupilot, which can be used as Non GPS position environment.
i have read this document ,it says that :" I companion computer to send position information to ArduPilot without the use of ROS."i want get this with out ROS is that will work ?
I did’t try this. But it suits your requirement (without ROS). But it can use ROS, which has more application for navigation.
This article explains how to setup an Intel Realsense T265 for use with ArduPilot as a substitude for a GPS allowing position control modes like Loiter, PosHold, RTL, Auto to work. This method uses a python script running on an RPI companion computer to send position information to ArduPilot without the use of ROS.
For RPi running Ubuntu, the installation process for
librealsensehas been detailed in this wiki. Follow the instructions to installlibrealsenseandpyrealsense2. Since we are not using ROS,realsense-rosis not required.
Try APSync Ubuntu image, which do not require ROS as doc says.
This person frequently recommends official documentation without fully understanding the subject.
A similar issue happened again: the writer refers to a Raspberry Pi 4B, but the guide provided is for a Pi 3B.
For reference, you can check my previous post (this link isn’t the only time I’ve noticed this guy on the forum):
https://discuss.ardupilot.org/t/what-is-appropriate-value-for-3dr-telemetry-module-radio-rssi/121696/20
I shared a link there showing a case where the official guide either overlooked or misrepresented important details, making it difficult for beginners to follow.
Simply posting links to official documentation isn’t always the best way to solve these types of problems.
You can provide links as a “reference,” but they shouldn’t be presented as the complete “solution.”
it’s so kind of you ! thank you very much !
@WangLouis hi brother i’m form hunan province ,i use the same hadeware for non-gps guided for look for bridge under , will you give me a img of you pi4 , i’m desired for it .
Please keep replies on topic. Posting a long series of screenshots to highlight a perceived documentation issue on a completely unrelated issue is not helpful to anyone, and possibly only serves to incite negative responses.
Posting screenshots of forum responses is also unnecessary, even when relevant. You can (and should) just link to the desired subject matter.
Please also refrain from accusations. Provide factual corrections when warranted and move on.
yes i think so ,we just desired subject matter, i have learn so much here !
