## Abstract A new satellite‐tracking method is proposed for a directional antenna installed on a car for L‐band land‐mobile satellite communication. This method uses both a fiber optic gyroscope (FOG) and a magnetic compass (MC) with an open‐loop control algorithm, which com pensates for the disadv
