Rover for Dji Matrice 300 RTK

[nikolaospaschalis (Nikos Paschalis)]

Hello

I own a DJI Matrice 300 RTK with DRTK-2 as a base.

I am looking for a Rover to measure GCP like Emlid Rs2.

What do you propose?

If you have network RTK and a cellular internet signal you can do everything with one RS2. Setup as a rover when shooting GCP’s and then a base to cast to the M300.

So using M300 DRTK as a base and RS2 as a rover correct ?

What @michaelL meant is to skip the DRTK-2 entirely and use the RS2 to send corrections to the drone via NTRIP. This works as long as you have cellular connexion.

Hi Nikos,

I’m not sure if DRTK can act as a base for Reach. Never got a chance to work with it. However, Michael and Gabriel are right: you can place GCPs with one Reach RS2 if you have local NTRIP service and good cellular coverage.

Also, if you test Reach RS2 as a base for DJI M300, please share your experience! We’re pretty sure it should work fine because we’ve tested DJI P4P RTK. But then we’ll know for sure

Thanks, Svetlana
I think I will stay with Michael and Gabriel.
I am planning to use DRTK as a base with the drone and use RS2 only for measuring GPC’s with NTRIP.
I will also try to test what you proposed

Just thinking out loud but if you have NTRIP and internet access couldn’t you just run the M300 off of that? The RS2 would be handy as a backup for occasions when your NTRIP and/or internet are not available or working properly. In that case you would performing PPK. This is always a tough scenario because you usually don’t know until you get there. We run an RS2 as a rover and a Yuneec H520E RTK with NTRIP and it has been really good but there has been a handful of occasions where RTK dropped for just long enough and we were glad we had the ability to PPK after the fact. After some bad experiences with the P4RTK I have been real leary of trusting RTK on a drone so I instituted the policy to run the PPK for verification as part of our workflow. The Phantom was dropping RTK on average about 5% and upwards of 10% at times and excluding a few times the Yuneec is around 3%.
