We propose a fleet of nanosatellites to perform an all-sky monitoring and\ntiming based localisation of gamma-ray transients. The fleet of at least nine\n3U cubesats shall be equipped with large and thin CsI(Tl) scintillator based\nsoft gamma-ray detectors read out by multi-pixel photon counters. For bright\nshort gamma-ray bursts (GRBs), by cross-correlating their light curves, the\nfleet shall be able to determine the time difference of the arriving GRB signal\nbetween the satellites and thus determine the source position with an accuracy\nof \∼10^\′. This requirement demands precise time synchronization and\naccurate time stamping of the detected gamma-ray photons, which will be\nachieved by using on-board GPS receivers. Rapid follow up observations at other\nwavelengths require the capability for fast, nearly simultaneous downlink of\ndata using a global inter-satellite communication network. In terms of all-sky\ncoverage, the proposed fleet will outperform all GRB monitoring missions.\n
