Among the world's four major navigation satellite systems, China's Beidou satellite has a unique skill in addition to navigation and positioning. That is short messages, which can be sent and received without operators' networks. Now this function has entered the stage of mass application.
A news conference on the achievements of the Beidou-3 short message communication service was held in Beijing on July 30.
China North Industries Group Co., LTD., China Mobile Communications Group Co., LTD., and others jointly demonstrated the new functions of Beidou short message communication service for Dazhong smart phones, as well as the achievements of satellite-ground fusion solutions and technical solutions based on Beidou 3 short message communication service.This marks a new stage in the development of BDS-3 short message communication service from industrial application to mass application.
The Beidou short message is developed based on the characteristics of China's second and third generation Beidou navigation satellite systems. It has both positioning and communication functions, and can realize two-way short message communication between Beidou users without the support of other communication systems, while other navigation satellite systems in the world do not have this function.
The Beidou-3 short message communication has been upgraded on the basis of the Beidou-2, which has improved the system service capacity and reduced the terminal transmission power.
In May 2021, North Industries, China Mobile, China Electronics Technology and other companies announced that Beidou short message communication into the mass mobile phone, innovative mobile communication coding and high sensitivity signal capture and other technologies, overcome the mass mobile phone volume constraints, high power consumption requirements of key bottlenecks, mobile phone & LDQUO; No SIM card change, no phone number change, no additional devices ” You can enjoy Beidou short message and mobile communication services at the same time.
