The Thunderbolt documents four filters that you can enable (PV, ALTITUDE, STATIC, and KALMAN). The KALMAN setting is not documented for the regular Thunderbolt. The Thunderbolt-E lists it as being available. Lady Heather gray's out the option unless you have a -E (but does let you try and set it if you have a normal Thunderbolt, no telling if it actually does anything). I think these filters are for receiver dynamics and not oscillator disciplining.
