I'm running INS app with u-blox zed f9P (NMEA protocol) and openimu 300ZI eval kit (also connecting 1PPS).
The output from IMU in .csv format has the first two columns that regard time information, namely TimeCntr and Time. Can anyone explain what these times are referred to?
This is useful if one want to fuse data in postprocessing with another KF (some time reference or time stamp to sinchronize GPS data and IMU sensors readings is needed).
Hope someone can help me.
