HADES

Additional information HADES

Hades satellite is offering radio amateurs a linear transponder for bidirectional SSB/FM/CW and digital modes communications as well as testing the platform for future amateur satellites. Regenerative repeater capabilities and limited experimental store and forward functionality will be provided as well. A camera is expected to fly as experimental payload.\r\nAs for Hades,its payload consists of a miniature camera module that sends the captured images as an audio signal in SSTVmode. The SSTV formats it uses are compatible with Robot36, Robot72, MP73 and MP115.\r\nThe design is based on the one used in the successful mission of the PSAT2satellite, an amateur radio satellite of the United States Naval Academy and brno University of Technology. This chamber has been operational since June 25, 2019: ( http://www.aprs.org/psat2.html ).\r\nThe camera chip is the Omnivision OV2640, which provides a resolution of up to 2M pixels and compressed output in JPEG. Resolution is limited by the CPU?s internal memory (MCU) that controls the camera to 320×240 (typical) or 640×480 maximum. The MCU selected for the control is the STM32F446RET6, which has the smallest possible footprint with connection to DCMI peripheral, necessary for connection with the camera.
