less than the actual ground speed because the change in slant range is smaller than the

inaccurate because the aircraft is moving away from the station and the slant range error

greater than the actual ground speed because the change in slant range is greater than the

exactly correct because the aircraft slant range is increasing at the ground speed due to the
