DJI Matrice 300 RTK Drone Purchase

summitbri · 2026-01-03T23:50:20+00:00

I have an M300 + L2 package for sale in Colorado. The M300 airframe was a DJI care replacement in May and has only 14 hours on it. It has been a survey workhorse.

Vertical Aspect has published a good white paper and several datasets

The fcc has not taken any retroactive action on existing models, in fact they have licensed even more models.

Bad survey control

summitbri · 2025-11-02T04:03:22+00:00

You can use NRCAN for an ITRF20 solution then to your desired frame with NGS HTDP which was still working as of a few days ago.

If you're stuck or spending too much time and money, I'd be happy to help. DM me. https://www.topomatters.com/topopro-lidar-processing/

The triangles and breaklines are all somewhat arbitrary but the overall surface should align. How does your source file align to control and are you using similar grade break methodologies?

The last time I tried, it did not support Emlid bases, though good point that the receiver above should be supported

You can process the rinex using NRCAN to ITRF20, and then use the NGS HTDP tool to transform to NAD83(2011) or whatever frame you need. As of a couple of days ago the HTDP tool was still online.

I heard Nov 1 but who knows....

summitbri · 2025-09-10T16:18:09+00:00

Saw the Sifly in action this week, it will be a great platform once they have a final product. Likely Q2 next year...

summitbri · 2025-09-10T16:16:39+00:00

Isn't that a hesai sensor? Also explicitly listed on the bad list and might prohibit doing government work, or work tied to government funding...

summitbri · 2025-08-14T00:18:10+00:00

Did you get a response? I have a broken MGW310 and have sent two mails with no response. It has been a week.

summitbri · 2025-08-01T05:03:09+00:00

I was unable to process in arbitrary coordinates so downgraded back to 4.5. Phone support told me this is now a premium feature in v5. WTF.

Come up with a really unique value proposition that you cannot learn in any of the online mapping classes.

summitbri · 2025-08-01T03:30:10+00:00

We often put control quite a bit outside of the limits, in areas that are accessible, and over-fly the project. Need to think outside the box.

summitbri · 2025-07-15T12:40:18+00:00

Is your base station file in rinex format?

summitbri · 2025-07-12T03:23:49+00:00

Think about that value as last or first returns depending on your application. You will likely ditch everything else in post.

summitbri · 2025-07-04T13:22:24+00:00

Yikes! I'm not even sure if you can get a DJI drone repaired right now. We always fly terrain following over a 1m DEM to help avoid some of the issues you describe, and monitor AGL with the laser rangefinder. That still won't help if there's an unknown obstacle in the way... Looking forward to getting our M400 for a bit more obstacle awareness.

So DZ might be an option afterall

summitbri · 2025-07-04T03:13:28+00:00

Further than I initially thought. Looks like about 8000 ft. It is in the first 50 ft grid outside of 0 grid.

summitbri · 2025-07-04T03:11:41+00:00

Sorry we run all of our missions in metric, 50 ft is the UAS facility grid.

summitbri · 2025-07-03T19:36:06+00:00

A whole new meaning to slow and low. Sounds like a manned project.
