XTraVel is a filter/smoother for jumping MLAT position reports developed by becker-aero.

​

Since target data from multilateration (MLAT) systems can be noisy, which results in “jumping” targets, a frequent request is to smooth the target track. XTraVel is designed to satisfy this demand. Additionally XTraVel can augment the MLAT data with the target track velocity vector if it is not provided by the MLAT system.
