A three-axis stellar sensor comprising a conventional stellar sensor for detecting the presence of light from a radiant body. The stellar sensor is mounted on a stable member located in a vehicle. The axis of the telescope of the sensor is parallel to a first line of sight to a first radiant body and a silvered mirror located at an angle of 45 DEG to the axis of the telescope provides a means to measure light from a second radiant body along a second line of sight 90 DEG displaced from the first line of sight. Additional means are provided to rotate and measure the mirror angle.
