VBOX 3iS Kalman Filter Status

Updated on Mar 4, 2026

The table below shows the hex and decimal numbers associated with Kalman Filter status.

The VBOX can have a number of these status flags active at the same time, so the resultant number shown in VBOX Test Suite or VBOX Setup will be a result of adding together the numbers of the active statuses shown below.

kf_NEWIMUVersion0x00011
kf_TestMode0x00022
kf_Use0x00044

Example
Kalman Filter Status = 61 (3D Hex)

32: kf_GoodLock
16: kf_IMUDataFound
8: kf_Initialised.
4: kf_Use.
1: kf_NewIMUVersion.

32+16+8+4+1 = 61
