RD120-6W Beidou RDSS Short Message Communication Board

The RD120-6W Beidou RDSS short message communication board is developed by our company based on our independently developed Beidou RDSS RF chip and baseband chip. It mainly consists of high-power amplifiers, RF chips, and baseband chips. Its functions can meet the requirements of users for satellite navigation positioning and short message communication on land and sea, and it has small size, low power consumption, and high reliability.

Military and civilian Beidou user machine manufacturers can quickly launch competitive Beidou user machines based on this board, which can be widely used in Beidou compatible satellite navigation, vehicle navigation, marine fisheries, drones, meteorological detection and other fields.
