PROBLEM TO BE SOLVED: To provide inexpensive mobile equipment for satellite communication by holding the direction of an antenna for satellite communication vertical at all the time in simple structure in spite of the direction of the mobile equipment for satellite communication. SOLUTION: This equipment is provided with an antenna shaft 3 for supporting the antenna for satellite communication, an antenna 1 for satellite communication supported on the antenna shaft so as to freely rotate for transmitting/receiving with a communication satellite and a gravity control part 4 for applying a weight to the antenna for satellite communication and has a configuration for always keeping the direction of the antenna 1 for communication satellite vertical with gravity in spite of the direction of the mobile equipment 2 for satellite communication. Thus, since electric control is unnecessitated, the structure of equipment can be made simple and inexpensive.
