Abstract
The invention relates to a mobile satellite communication system hand-held terminal which comprises a front shell assembly and a rear shell assembly in a seal assembling mode. The front shell assembly comprises a front shell, a display screen, a keyboard plate and a base band plate. The rear shell assembly comprises a rear shell, a radio frequency plate, a radio frequency plate shielding cover and an antenna. The radio frequency plate shielding cover is installed outside the radio frequency plate in a sleeved mode. The mobile satellite communication system hand-held terminal is reasonable in design, simple in structure and capable of effectively eliminating mutual interference between the base band plate and the radio frequency plate through the radio frequency shielding cover, so that working is more stable. Meanwhile, the mobile satellite communication system hand-held terminal has a good waterproof function through the seal assembling and is adaptive to field work environments.
