24/// # Important
25/// Some software, like ODTK, processes each measurement as a scalar. Nyx processes the measurements together.
26/// As such, if the prefit on range is bad, then the Doppler measurement with the same time stamp will also be rejected.
27/// This leads to better convergence of the filter, and more appropriate results.
