Payload project for hamradios and satellites amateurs.
Our satellite payload project aims to develop a technology demonstrator to study and demonstrate the agility of satellite communication protocols and spacecraft programs. This project responds to the curiosity of radio amateurs and space enthusiasts by providing a platform for experimentation and innovation in the field of space communications. The project's primary mission is to investigate and demonstrate the agility of radio communication protocols and onboard software for satellites.
To this end, the secondary missions are:
- digipeating (data) traffic from amateur operators in several modes, like CATS and M17.
- providing mailboxes to radio amateurs in several modes, like CATS and AX25
- sending telecommands to flat-sats and terrestrial rovers built by radio amateurs with students, in digital modes like AX25 and CCSDS USLP.
- sending images and other data computed by the execution of software programs taking our camera as data input, in modes like SSDV over AX25, CW, SSTV (to be confirmed).
- sending beacons in several modes, likes AX25, ECSD SDLP, CW, M17.
Radio amateurs and space enthusiasts will be able to participate in space communication experiments and demonstrations, using authorized amateur radio frequencies and respecting current regulations.
More precisely, this payload is made of one SpaceRadio, which will be IARU coordinated. Indeed, F4JXQ, F4MHW, and F4IWP are all 3 participating in this project and are really willing to experiment this aspect and animate the hamradio community.
The payload is part of a multi-service host satellite and also contains other experiments, including students' one. Yet, thanks to the host, those sub-part are clearly separated to fulfil the IARU's requirements.
The following logical architecture diagram summarize some sub-systems and their interactions like the multi-services host satellite, our spaceradio, a students' experiment, and various stakeholders.
AMSAT-IARU_Link_Model_Rev2.5.5-FOSM-1 contains the current analysis of the radio link budget. We are leveraging the open source radio system called Spino. and some of its modes are decribed in its code repository. We will add type of transmission thanks to our added WASM engine, eg transmitting Cats packets and maybe M17 also.
