A brief specification of Hermes, an UAS video and data-link system.
Transmitter: Designed as an extension board for NanoPI/RPI MiniPC. With a minimal weight and the possibility to add custom software, data and signal processing algorythms. The device can transmit video and any type of RAW data down to a ground station receiver.
For example it can downlink a video stream from an RTSP camera, data stream from UART interface, and a 3D point cloud from a 3D camera.
Receiver: Designed as an extension board for NanoPI/RPI MiniPC. The receiver is capable of operating in a diversity mode in which it's capable of receiving weak downlink signals using both independent RX paths where a maximum ratio combining algorithm is implemented. The devive provides received data streams via an Ethernet or a WiFi link. The receiver module consists of GPIOs to be used it for external auxiliary devices like i.e. antenna tracker. etc.
