The CORONAS-PHOTON mission is the third satellite of the Russian CORONAS program on solar activity observations. The primary scientific objectives of the project are the investigation of the processes of energy accumulation and its transformation to the energy of accelerated particles during solar flares and the study of the mechanisms of acceleration, propagation and interaction of fast particles in the solar atmosphere. We give the essentials of the Russian satellite project CORONAS-PHOTON developed in the framework of the Russian space program. The set of onboard scientific instruments will allow one to study the hard electromagnetic radiation of solar flares in a wide energy range from extreme UV up to high energy y-radiation (-2000 MeV) as well as neutron and charge particle fluxes in the satellite orbit. The overview of observational objectives, the main parameters of the instruments and their interfaces with the satellite telemetry and command systems are presented. The launching of the satellite in a circular orbit with a height from 500 to 550 km and an inclination of 82.5° is planned for 2006.
