The TC-SC2 Bridging Digital Terminal is a digital one that supports the functionality of the Beidou III system RDSS/RNSS. The product is internalized into functional units such as the Beidou multi-frequency antenna, radio frequency, base band and master control, which enable satellite positioning, navigation, short-form communication, etc. At the same time, the equipment can expand the 4G network communication function and the two-modular communications of the Real BeiDou+public network.
Products can be widely used in such areas as satellite communications, location monitoring and emergency communications.
