InCommand service is able to provide dynamic affordable and real-time L-Band capacity for LEO satellites anywhere on the globe. It provides operational efficient communication links for time-sensitive applications such as Earth Observation (EO) or spacecraft operations via Inmarsat’s geostationary ELERA network. No additional ground network infrastructure is required. We have designed, implemented, and tested the first XLink L-Band transceiver that will use the Inmarsat’s InCommand service.
