It is a candidate technology that could enable for the first time 5D tracking in space using LGAD Si-microstrip tracking systems. The intrinsic gain of LGAD sensors may also allow to decrease the sensor thickness while achieving signal yields similar to those of Si-microstrips currently operated in Space. In this document we discuss the possible applications and breakthrough opportunities in next generation large area cosmic ray detectors and sub-GeV gamma-ray detectors that could be enabled by LGAD Si-microstrip tracking detectors in Space. We propose the design of a cost-effective instrument demonstrator on a CubeSat platform to enable and qualify the operations of LGAD Si-microstrip detectors in space. © Published under licence by IOP Publishing Ltd.enjournal article10.1088/1742-6596/2374/1/012046https://iopscience.iop.org/article/10.1088/1742-6596/2374/1/012046
