DJI m300 / L1 with up to date firmware, DJI Terra also newest.  

I have just got error 8007 on DJI Terra processing of four subsequent flights in the middle of a day. Flights before and after those four are not affected.

All of them are linear missions with 3 parallel passes, in terrain follow mode, IMU calibration checked, custom RTK VRS reference station used (dense network, and really close to one of stations), RTK FIX etc. All missions created in exactly the same way. And all of them “successfully finished”.

I have tried to postprocess them with static data (VRS RINEX next to area of flights, 4 constellations, 1s, RINEX 3.03 etc), but with exactly the same results.

Dear DJI, it is really a disaster to realize that “successful missions” taken hundreds of kilometers from home in CTR coordination regime are actually useless.   

Is there any other thing I could try to recover those data ????

Do not use VRS !

Well, got the same results after postprocessing data with RINEX from near physical station (not VRS). As I understand whole thing, when postprocessing data with static RINEX this issue should not be related to VRS or other source of RTK corrections. It should be like scanning with RTK off, intended for PPK. Or do I miss something ?

How close is "near physical station"?

~12 km. As far as i remember 30 km was an estimated limit after wich You should expect rapid quality degradation, but this is not processing at all. Fragment of log :

If you want a deeper insight, please send (google drive or something else) me the whole folder of the defective mission. Without .LDR file, without JPG pictures. And add the third party rinex file.

Sorry for the belated reply. The 8007 error may occur if base station data cannot be decoded or the RTK data is not FIX. Please try to collect the data again, make sure the base station data used is a supported protocol, and double-check that the DJI Terra is V3.6 or above.
Please keep us updated if the issue is the same.
