  HERMES-TP/SP (High Energy Rapid Modular Ensemble of Satellites Technologic
and Scientific Pathfinder) is a constellation of six 3U nano-satellites hosting
simple but innovative X-ray detectors, characterized by a large energy band and
excellent temporal resolution, and thus optimized for the monitoring of Cosmic
High Energy transients such as Gamma Ray Bursts and the electromagnetic
counterparts of Gravitational Wave Events, and for the determination of their
positions. The projects are funded by the Italian Ministry of University and
Research and by the Italian Space Agency, and by the European Union Horizon
2020 Research and Innovation Program under Grant Agreement No. 821896.
HERMES-TP/SP is an in-orbit demonstration, that should be tested starting from
2022. It is intrinsically a modular experiment that can be naturally expanded
to provide a global, sensitive all sky monitor for high-energy transients.
