KW/M500C type (TDMA/Spread Spectrum) satellite master station terminal
The KW/M500C satellite master station terminal is suitable for traditional satellite and high-throughput satellite data link communication systems, serving as the central node device in data link satellite communication systems. It adopts carrier-grade redundancy design, with hot standby configurations for channel, clock, and power supply boards. Relying on traditional or high-throughput satellite resources, it achieves unified access and management of end stations. It supports the configuration of TDM/MF-TDMA communication technology system boards, providing terminal users with private network or Internet services such as massive data transmission.
