PSLV Orbital Experimental Module

The PSLV Orbital Experimental Module (POEM) also known as PS4 Orbital Platform (PS4-OP) utilizes the spent PSLV fourth stage (PS4) to provide a long duration in-orbit platform for hosting payloads. This would be first time that such PS4 based orbital platform would orbit the Earth as an actively stabilized platform post completion of main mission. Attitude stabilization is done using eight Helium based
