Abstract: This application provides a wearable device, including an antenna radiator, a Satellite communication module, and a processor. The Satellite communication module includes a satellite positioning unit and a short packet unit. The satellite positioning unit is configured to obtain, under control of the processor, global positioning information by using the antenna radiator. The short packet unit is configured to multiplex, under control of the processor, the antenna radiator to receive or send a Satellite short packet. This application further provides a Satellite short packet sending method applied to the wearable device, and the method includes: When receiving an input signal and/or when determining that a current environment meets a trigger condition, the processor of the wearable device controls the Satellite communication module to send the Satellite short packet by using the antenna radiator.
