GRBAlpha

Second Slovak satellite, built in international cooperation, and first 1U CubeSat ever to detect gamma ray bursts.

GRBAlpha is a 1U CubeSat carrying a 75 x 75 x 5 mm CsI(Tl) scintillator, read out by a dual-channel multi-pixel photon counter (MPPC) setup, to detect gamma-ray bursts (GRBs). The GRB detector is an in-orbit demonstration for the detector system on the Cubesats Applied for Measuring and localising transients (CAMELOT) mission. While GRBAlpha provides 1/8th of the expected effective area of CAMELOT, the comparison of the observed light curves with other existing GRB monitoring satellites allowed us to validate the core idea of CAMELOT, i.e. the feasibility of timing-based localization.
