PROBLEM TO BE SOLVED: To provide a receiver device which can satisfactorily track a satellite and which can stably receive even if an antenna with less margin in a reception level or having a narrow directional half power angle in a vertical direction is used. SOLUTION: A vertical direction angle sensor 118 detecting the angle of the vertical direction of the installation position of an antenna 101 is installed in a position matching the directional boresight direction of the antenna 101. A reception level detection part 115 detects the level of the reception signal of the antenna 101. A vertical direction automatic track control part 119 controls the operation of a vertical direction motor driver 114 so that the boresight direction of the vertical side of a beam in the antenna 101 matches the direction of a satellite 250 based on the detection signal of the reception level detection part 115 and the detection signal of the sensor 118. Even if the angle of the vertical direction of the installation position of the antenna 101 changes, the boresight direction of the vertical side of the beam in the antenna 101 can instantaneously be turned to a satellite direction.
