DJI Phantom 4 RTK, Mavic 3 E RTK, M300 P1 - PPK and geotagging tutorial

[@origamitianfu2972]

Cómo hago para geoetiquetar fotos si mis archivos de GNSS (rinex) son de 12 horas y mis vuelos son de 15 minutos de un phantom 4rtk?

[@harley0268]

Work using M300 with H2T camera ?

[@REDcatchGmbH]

We never tried. When using H2T, is a *.obs and *.MRK file available? If so, it will work. If not, no PPK is possible.

[@duguayjason]

With the M300 and the P1, does one need to specify the differential between the RTK sensors of the drone and the P1 image sensor to get an accurate elevation map? My maps are all about 0.2 m too low and my hunch is that this is caused by the differential between the image sensor and the RTK sensor. Please let me know if I am wrong.

[@duguayjason]

@@redcatchgmbhteammember3229 Thank you for the clarification. I am not sure about your first point. For the second point, would the P1 not being calibrated cause a systematic shift of approximately 0.2 m downwards in the vertical? How does one calibrate the camera? I can confirm I applied the geoid model. Thank you for your help with this.

@@redcatchgmbhteammember3229 Thank you, I will try this and let you know how it goes.

How can you use your DJI RTK 2 as base station ? Is it not only for rtk ?

[@REDcatchGmbH]

DJI DRTK2 base station also records a *.dat file, which can be directly imported into REDtoolbox software

when i tried to launch i get this error Failed to execute script Pyi_rth__tkinter i tried on 3 diferent computers

[@RodrigofCabral]

I purchased the software 1 year license with upgrade. would there be an option to create the data for DJI TERRA? It builds only for Metashape and PIX4d I don't do work in RTK, for signal reasons.

[@mikealpha4462]

could it work with multi-flight multi-logging mission? we will map a verry large area which can nit be done in one day

[@Katja-jv8ys]

I am stuggeling to find the .mrk and .bin files. We use the DJI M300 combined with a DJI Zenmuse XT2 Thermalcamera. I found a Folder with "FlightRecord" of each flight we conducted. But these files are .txt. Is there a way to convert it to .mrk?

[@REDcatchGmbH]

Hi, I'm not sure if the XT2 is able to save the RINEX and trigger files. If they are not in the folder, this camera might be not compatible for PPK

[@Katja-jv8ys]

@@REDcatchGmbH Thanks for the fast response!

[@anthonyosmond2493]

I think you should make it clear that you the igs absolute antex files installed to take into account your phase CTR offset on your base, as this can put your solved camera ctrs out by a very large error in height, you have sent me the install script and files Hans, it should be standard

[@REDcatchGmbH]

Not everyone require an antex *atx file. But sure, in upcoming version 3.0 of REDtoolbox this function will be included. Cheers

[@REDcatchGmbH]

@@anthonyosmond2493 You can get your copy of REDtoolbox here: www.redcatch.at/redtoolbox/#buy and as soon as v3.0 is released you will be informed by email. (Approx 2 weeks). A multiple license discount is available during checkout :)

[@dainel40]

Where do you get the .mrk and .bin files? I just flew a mission with RTK today and I dont have those files on my SD Card?

[@REDcatchGmbH]

For P1 camera the files should be located next to *jpg images. If not, maybe check firmware update. In case this does not work you may have to contact DJI directly

[@dainel40]

@@REDcatchGmbH I have a L1 and all the latest updates. there are no signs for the .mrk and .bin files

[@REDcatchGmbH]

@@dainel40 Hi, mrk and bin files are for P1 camera. Not L1. You have to use DJI terra for processing Lidar data.

[@eduardonunez564]

Thanks for the video. This work with any gnss base (emlid, triple. Etc)? Or only work with DJI base?

[@REDcatchGmbH]

Hi, any GNSS device able to record RINEX data (v2.11 or v3.x) can be used as base station data. Eg. EMLID RS2, Trimble, Topcon, Leica, DJI D-RTK 2, ....

There is some kind of demo license to test it
