The invention discloses a portable satellite communication service box which comprises a host seat and battery seats. The battery seats are distributed in the two sides of the host seat symmetrically,a front gap of each battery seat is provided with an arc bushing, one end of each arc bushing is rotationally sleeved by a movable ring, hollow rotating shafts are arranged in the two sides of the front end of the host seat respectively, the movable rings are fixed to the hollow rotating shafts via hollow shaft couplings respectively, angle display discs are fixed in the outer sides of the movable rings respectively, and each of the two sides of the host seat is provided with an antenna and a long indication line. The rear ends of the two battery seats are integrated via a connecting plate, and the connecting plate is connected to the back side of the host seat via a support mechanism. A pipe system between the host seat and the battery seats is designed reasonably, and a power supply cable in the battery seat is input to the internal of the host seat via the arc bushing, movable ring, hollow shaft coupling and hollow rotating shaft, and supplies power to electrical components in thehost seat; and the angle display discs arranged in the outer sides of the movable rings cooperate with long and short indicating lines, so that the inclination angles of antennas can be observed and adjusted accurately in the lateral part.
