Abstract
A navigation satellite system reception apparatus can eliminate multipath signals without direct waves of invisible satellites and can implement time synchronization. A satellite orbit information acquisition unit acquires orbit information of a satellite, an installation position information acquisition unit acquires position information of an installation position, an azimuth meter acquires azimuth information of an azimuth in which a wall surface of a nearby obstruction extends, and an azimuth mask generation unit calculates a mask region for selecting a satellite to be a target of processing based on the azimuth information. A positioning and time synchronization processing unit calculates an azimuth and an angle of elevation of each satellite, selects a satellite to be a target of processing bas, and performs the positioning processing or the time synchronization processing based on a satellite signal received from the selected satellite.
