Progress on SVOM Satellite Development

SVOM(Space-based multiband Variable Object Monitor)is a Chinese-French space mission mainly designed to study Gamma-Ray Bursts.The satellite carries four instruments to detect and localize the prompt GRB emission and measure the evolution of the afterglow in the visible band and in soft X-rays,and a VHF communication system enables the fast transmission of SVOM alerts to the ground.The ground segment includes an array of wide-angle cameras and two follow-up telescopes.It was launched into an orbit of about 635 km on 22 June 2024,with three years of nominal operations and an extension of two years.
