So far, the Beidou Short Message Simulator with the most comprehensive business functions and the highest technological maturity covers regional and global short message communication, as well as RDSS positioning and testing capabilities.
RTS9000 is a Beidou RDSS satellite signal simulator for global applications, supporting the transmission of S-band outbound signals for regional short messages and the reception and calculation of L-band inbound signals. It has the B2b downlink signal simulation and L-band inbound signal reception capabilities required for Beidou-3 global short message communication, position reporting, and emergency search and rescue functions.
The RTS9000 closed-loop testing system has functions such as outbound signal transmission, inbound signal reception and processing, and user equipment data interface. It has the ability to identify, finalize, and authenticate various RDSS user equipment, such as handheld, vehicular, and command type user machines. It supports the Beidou No.2 RDSS, Beidou No.3 RDSS, Global Short Message Signal System, and User Equipment Interface Protocol.
