Tiantong Satellite Fixed-Mobile Integrated Terminal combines a satellite phone with a smart docking base, enabling seamless switching between fixed and mobile operation. Indoors, the base connects to an external antenna to maintain 24/7 satellite signal reception, functioning as a desk phone for command centers. Outdoors, the phone can be detached and carried into the field. The system integrates BeiDou positioning, one-key SOS alerting, and periodic location reporting.
