Abstract
A message filtering system is provided for filtering generally broadcast messages received by a movable unit. The generally broadcast message includes an information segment including location, time and/or velocity information relating to an event of potential interest to the unit which has occurred in the past and which has continuing consequences for the unit. The movement history of the unit is stored along with data selection information and a determination is made as to whether the information contained in the broadcast information segment is of interest based on this stored information.
