URESAT-1 – A chess playing ham radio satellite

URE report Intensive work is underway to make URESAT-1 available before the end of the year. If all goes according to plan, URESAT-1 will launch aboard a SpaceX Falcon-9 rocket from Cape Canaveral in October.

A translation of the post by Spain’s national amateur radio society URE says:

URESAT-1 is based on the architecture used in the GENESIS, EASAT-2 and HADES missions but will include significant improvements, such as a 32-bit computer compared to the 8-bit computers of the previous satellites and improvements in the mechanisms of deployment of antennas and batteries.

As for its functionalities, it will have a VHF / UHF FM repeater and FSK frames, like its predecessors. This will allow voice QSOs and digipeating of AX.25 and APRS frames.

The payload is not yet defined, but it could be the same SSTV camera that flies in HADES, a thruster or some kind of experiment. Talks with universities and companies and is expected to be closed in the coming weeks.

One of the projects that is confirmed is a chess game that will allow radio amateurs to play having as an opponent the on-board computer sending FSK frames with the movements, to which the on-board computer will answer in its telemetry. Several radio amateurs are working on the project and if it is completed by the time the satellite is due to be delivered, it will be included.

The expected orbital altitude is around 525 km and the inclination will be polar, probably around 97 degrees, which would place it in the same orbital plane as its companions EASAT-2 and Hades.

URE has created a blog in WordPress where the status of the project will be reported, including details of the functionalities and technicians.
