Embodiment Construction

[0026] Such as Figure 1-3 Shown is a schematic diagram of the structure of the present invention. Since the multi-touch high-definition screen is used, it is designed in the shape of a saddle, thereby protecting the screen to a certain extent. The earphone 1 (speaker) is arranged on the upper end of the handheld terminal, and is designed in a circular arc convex shape. The antenna interface adopts 360-degree rotation and folding, and the headset jack 2 is designed to be sealed with a rubber plug near the root of the antenna, the power charging interface is designed at the bottom, the navigation screen 3 is set in the middle of the handheld terminal, and the bottom of the navigation screen is set with a number key 4 .

[0027] The satellite communication and navigation intercom handheld terminal in China includes: an intercom module for voice communication between users; a positioning and navigation module for locating the user's position; a short message module for data tran...

Description

technical field [0001] The invention relates to an intercom hand-held terminal for China Regional Satellite Communication and Navigation (CAPS). Background technique [0002] A handheld terminal refers to a portable data processing terminal with the following characteristics. It has data storage and computing capabilities (generally with an operating system), can carry out secondary development, can communicate with other devices for data, and has a machine-machine interface. Specifically, it must have display and input functions. Handheld terminals are divided into industrial handheld terminals and consumer handheld terminals. Industrial handheld terminals include industrial PDAs, barcode handheld terminals, RFID handheld terminals, etc. The characteristics of industrial handheld terminals are strong and durable, and can be used in many places with relatively harsh links. At the same time, a lot of optimizations have been made for industrial use characteristics. Moreover,...
