Description

Technical Field

[0001] The utility model relates to the technical field of communication data transmission, in particular to a handheld terminal based on satellite positioning and communication data transmission. Background Art

[0002] Satellite communication portable terminal, this type of terminal provides users with a portable multi-service satellite communication platform, allowing users to easily establish satellite communication links with the command center or other terminals no matter where they are, in order to transmit images, voice, data and other services.

[0003] At present, communication technology equipment such as mobile phones, satellite phones, walkie-talkies and Beidou short message terminals have their own limitations. For example, mobile phones cannot be used in signal blind areas, and walkie-talkies are limited to short-distance broadcast communications, which greatly limits their use in emergency environments such as earthquake relief. Communication satellites themselves cannot locate and navigate, which has limitations in the field of outdoor operations and is difficult to afford expensive charges. Beidou short messages use text communications and need to be entered character by character, which is not convenient for promotion and use, and the interaction time is long, delaying rescue. Therefore, the simultaneous interpretation of voice and positioning based on Beidou has opened up a new technical path for outdoor communications and emergency rescue. Therefore, a handheld terminal based on satellite positioning and communication data transmission is needed to improve the above problems. Utility Model Content
