Product Introduction

The Beidou Data Transmission Terminal is an integrated data transmission device supporting the RDSS/RNSS functions of the Beidou-3 system. It integrates multiple functional units including a Beidou multi-frequency antenna, RF, baseband, and main control, enabling satellite positioning, navigation, and short message communication. The device can be extended with 4G network communication capabilities, achieving dual-mode communication with Beidou + 4G networks. It is widely applicable in fields such as satellite communication, location monitoring, and emergency communication.
