Hoping to get some insights regarding some surveying related questions I've received from a potential construction company client. In short, they often build near railway lines and must monitor the tracks to ensure they don't shift/move result of excavation or other construction activity. They...

I noted in a recent test that the "absolute altitude" is being calculated based on the equation: ellipsoidal height + relative altitude, whereas one would expect the equation: ASL + ALT (relative altitude). In the example below, ASL is shown to be 115.2m and ALT is shown at 0.0 (i.e., the...

I managed to figure it out on a test flight yesterday. Basically, I had to add altitude by trial and error to get the drone to fly at 120m above takeoff point when using ASL. The reason I am using ASL is because I did a flight for a surveying company where my mission parameters were set to ALT...

Good information, thanks. One other question for you: when you set a mission to use ASL do you need to add altitude to ensure you are flying at X ft above sea level? For instance, I want to fly a mission at 100ft where the elevation at takeoff point is 200ft above sea level. Would I add that...

Thanks J, do you use a sim card in the M300? If so, can you provide details?

Recently testing custom network RTK for my M300 and despite having the credentials correct,, I was not able to get an RTK connection with "fix/fix" status until I connected to wifi hotspot on my phone. Wondering whether this was a coincidence or if wifi dongles, sim cards, etc., are a...

So I have watched the tutorial from DJI to setup RTK "custom network" but the missing link is identifying a service provider in North America. Contacted DJI directly but they said the service is only available in China. Has anyone used RTK without a base station via "custom network"? Thanks.

Hi John, good to know it's not my M300. After more research, I found the message below from another M300 user on the DJI forum. Seems to make sense. "I fly missions above air fields : since latest release Air Sense got smarter. Before it's was alerting you for each and every airplane coming...

Since November 2021, I have noticed that AirSense in my M300 is no longer working. I hadn't flown since then, but flew again this week and definitely confirmed it's not working as it was prior to November. No indication of any aircraft in the area regardless of their obvious presence ( I could...

Looking for information on mapping missions using M300 with DJI P1. Specifically wanting to create 3D map for golf course and would like to know more about workflow, settings, preferred software (e.g., DroneDeploy, Pix4D, etc.).

Figured it out - go to Mission, press SELECT, then use forwarding arrow bottom right of screen.

Can someone provide instructions on how to export a KML file created on the smart controller in Pilot to the external SD card?
