If I have a number of sensors whose measurements arrive at the same time - how can I handle them properly in the Kalman filter?

P.S. The measurements are not necessarily taken at the same time but I only receive them batched together.


If your measurements are batch, so is your filter.

You can do a number of things.

You can sequence your measurements in natural order and update the filter for each.

You can do the previous and then approach the problem as a fixed lag smoother.

There is a literature on out of sequence and delayed updating as well, like:
