GRBAlpha is a 1U CubeSat in-orbit demonstration mission, carrying a 75 x 75 x 5 mm CsI(Tl) scintillator detector in order to detect gamma-ray bursts and similar high-energy counterparts of violent astrophysical events at the edges of our Universe. The PI of the project is András Pál while the satellite is built by a collaboration led by Konkoly Observatory of the Eötvös Loránd Research Network along with Hiroshima University, Spacemanic s.r.o., Needronix s.r.o., Eötvös University, Nagoya University, Brno University of Technology and Masaryk University while the launch contract and radio license is provided by Technical University of Košice. Our primary goal is to demonstrate the feasibility of the timing-based localization of such energetic phenomena with a fleet of nanosatellites bearing scaled-up versions of our detector setup. See also this paper about more details about GRBAlpha. In fact, GRBAlpha is the smallest considering both operational and built ever astrophysical space observatiory and it is also a technology demonstration for further initiatives such as CAMELOT. The complete list of GRB and related detections are maintained by our group at Masaryk University.Please countact us (via the address apal.[atsign].szofi.net) for any details about the project! Radio enthusiasts and radio amateurs also encouruged to follow our satellite, either via the SatNOGS network or individually.
