RTK for M3T

[JCDiaz]

I have heard about the RTK technology to help with eventual interference while inspecting power lines, cell towers and even methalic structures.

Like to hear your opinions about this. I will receive my M3T in a couple of days.

It won't work for that purpose because it is only 'single (puck) RTK'.

You need 'dual RTK' like what's on the Matrice 30 series in order to gain the benefit of using RTK to resolve environments with strong EMF interference. If you look at the M30/M30T you'll see it has two pucks, one on each rear leg. It has to have two RTK modules with some separation in order to effectively calculate a heading. The aircraft knows the precise location of each puck, so it can use that info to determine it's orientation in real-time, in the event the aircraft's onboard magnetic compass is unable to detect heading due to strong environmental electromagnetic interference.

That said, the Mavic 3 Enterprise series (M3E/M3T) RTK module provides improved positional accuracy only. This is great for survey work, mapping, maintaining positional stability in operating in elevated wind conditions, and my favorite... perfect automated landings every time! With RTK your aircraft will land on a dime - everytime!

Actually the RTK is not great on the M3T for survey or mapping. The Mavic 3T does not have Time Sync, which is needed to get the precise coordinates and elevation written to each image. When mapping with it, you will get images with accuracy values in Pix4D or Metashape, but they will not be centimeter accurate.

The Mavic 3E and Mavic 3M both have Time Sync and therefore can create accurate maps and models.

You can always use ground control points if you needed centimeter accurate maps with the Mavic 3T.

For the Mavic 3T, the RTK module is for accurate positioning only. I use the similar RTK module on my Mavic 2 Enterprise Advanced and I use it to run precise repeatable inspections with images and videos. It works great when overlaying and comparing videos and images.
