Local Reproduction/ CA - YOW region - DJI Air 2s - OcuSync 3.0 about dronesecurity HOT 11 OPEN

@Vlad71527 - unfortunately your images don't work anymore here (404 from github)

The first one looked like a regular data packet, with a (variable; from a certain set) ZC symbol at the beginning, in the middle, and at the end.

The second one looked like a DroneID packet, with two (fixed - always 600 and 147) ZC symbols in the middle (around a data symbol). The latter should decode just fine. Do you have timestamps for within your capture?

So far I have not seen any OcuSync version not using DroneID packets in the same format. (The only difference seems to be whether the empty prefix symbols are there or not.) Difficulties to decode seem mostly from the fact that the somewhat basic synchronization algorithm used here requires a very good quality signal.

I just received my USRP B205mini - setting up
I don't expect it to detect my Mavic 3 classic or Air 2s, hopefully the mini 2 works

@fmichaelobrien @n0vichkov looking forward to hearing how it went with occusync 2.0! please update if you were successful. I haven't yet seen a successful reproduction and am waiting for someone to confirm before I dive in.

Still at step 1: new to SDR - setting up my B205mini using a VMware Ubuntu VM on one of older Mac's (intel chip)

Hi, we are trying to reproduce the same and after our investigations we got an answer that proposed decoding method does not work with DJI Air 2S with OsuSync 3.0 (we have tested live receiver (with some changes for USRP X310 as RF) and offline decoder. I suppose, that modulation and decoding method differs

If you post a baseband recording of Occusync 3.0, I can take a look to see what the differences are wrt 2.0.

Hi aholtzma-am

Can you post the baseband files?

Is there any way to make this work with antsdr or bladeRF?

from dronesecurity.

I am using X310 for this, has someone used it for this project, if yes what I should change to make the code work for my x310
