Modifications to Multi-beam Systems for DRRM

An initial study of the emergency communications services offered by current multi-beam satellite systems for disaster relief and rescue mission (DRRM) effort has been conducted within the frame work of DVB and LTE/5G in ETSI. A multi-beam communications satellite system with its unique coverage and beam hopping advantage can be adapted to provide DRRM communications services when and where the other communications services are absent. A proposal of using partial multi-beam system resources for the DRRM is made and a sample design of the digital analysis filter bank for the modified satellite transponder is presented and partially optimized.
