The S-band transceiver is an essential communication device for satellites, primarily used for communication with ground stations. The transceiver under development is designed to be compact and lightweight enough to be mounted on ultra-small satellites, and supports multiple modulation methods to enable high-speed communication. This enables rapid transmission and reception of large data such as images and communication with various ground stations, facilitating swift commands from the ground and achieving more advanced missions.
Features
- Compact and lightweight
- Supports multiple modulation and demodulation methods
- Achieves high bit rates for both transmission and reception
- High reception sensitivity
- Easy connection with OBC (On-Board Computer)
