"I connected the GPS with the PC via USB cable and using U-center I could change the type of message that was send by the GPS to the one that matches the LiDAR needs. I can't remember exactly where I did this modification, but I think it was pretty…"

Hello, guysI'm having some kind of bug while trying to create a Survey Grid mission.I'll add a sequence off photos showing the procedure:Flight Plan, Draw Polygon and AutoWP Survey GridAnd then the window that pops-up has no information at all.

"Matej,

I'm sending 3 images. The first one is the best that I could reach so far. But in this cloud, I didn't use any GPS nor IMU data. The cloud was created only using linear distances between the laser frames.
The second I used only one axis of…"

"Matej,

I just did some research on the hardware that  you mentioned, because I didn't know them. I'm not sure if I understood them correctly. Correct me if I'm wrong. The Trimple AP20 and STIM300 have an internal IMU and I can connect a GNSS to it,…"

"Hi, Matej

Do you know the math? I'm using Craig Glennie's papers to develop mine. 
Do you think this is accurate enough? I only use the general formula, not the  Jacobians' one. Matej Miljko said:
Hi Rohan, I think you got it wrong. Veloview does…"

"Yes, I used it, but I had no luck trying to create a map with it.
I think that a GPS RTK would be perfect, but the VLP16 is extremely limited with the GPS it accepts in its Interface Box. So I think the best solution is to connect a simple GPS to…"

"Hi, Rohan

I managed to connect the GPS, but I couldn't map anything with precision. I still have no idea how to map an indoor area. For outdoor mapping, I sync the GPS and IMU data from a pixhawk fc with the LiDAR points, but there's no precision…"

"Hello!

Do you know someone who has used it to precisely land fixed wings? Do you know their experience?

Thanks in advance! Laser Developer said:

Hello, guysI'd like to know what are your experiences using Lightware and TeraRanger rangefinders.I know they have different sizes and different operational voltages also.But which of them is more precise and realible for landing?I'm always flying…

"Hello, Matej

After many tries, I could make it work.
I had to do exactly as you said, reprogram the ublox using u-center and disabling every GNSS except GPS. I also had to access the pin 3 of ublox m8n to get the PPS.
But besides that, I had to…"

Hello,I have a fixed wing with a PixHawk flight controller and I'd like to know if it's possible to program it to, while landing on deep stall, the motor has the ability to invert its rotation for compensanting the wind and maintain the correct…

Hi,Has anyone ever tried a setup where you have used an ublox M8N to connect to the LiDAR from Velodyne? I did all the wiring connections as you can see on my diagram. I got a PPS Locked on the LiDAR, but no GPS coordinates. Someone has already make…

I've done some research on this  topic, but I couldn't find nothing recent, so I'd like to know if anyone has tested it recently and if it improves that drone performance

I bought a T960 hexa frame, and I'm currently installing a PixHawk that I bought from HolyBro, and I usually use the 3.1 version, but I've never tested the other ones...
