Post processing with tightly coupled GNSS+Base Station+IMU

Hi,
I am from the surveying and mapping community and focusing on the accuracy rather than realtime applications.
The golden standard is to use tightly coupled GNSS+Base Station+IMU for the estimation of position and angles, i.e. Inertial Explorer or POSPAC UAV/MMS.

I would like to ask if this is also supported for OpenRTK or INS100?

Regards,
Han

@Han-Hu I am sorry ,but our data format is different from what you said.

@zrs A related question. Does INS1000 support this kind of processing (using Inertial Explorer for post processing).
I have seen from the docs saying
... The system can also record all tracked dual frequency multi-constellation measurements for post-processing...
Is the post-processing the same thing?
