Description

The objective of Phase 2 is to build a reliable, lightweight, programmable, multi-mode, miniaturized EVA Software Defined Radio (SDR) that supports data telemetry, voice, standard and high-definition video. The proposed radios would be part of an advanced, incrementally expandable wireless network for securing and accessing lunar data assets. For improved reliability and to assure stand-alone functionality, the network would support a real-time 3D location function using site-assisted navigation and utilizing TOA/TDOA methods. To achieve unparalleled power consumption efficiency, Lexycom proposes the use of QoS-aware, data traffic dependent waveform selection. We have estimated that additional reduction in power consumption can be obtained by utilizing cognitive selection of the operating mode of the EVA transceivers. We plan to use an innovative RF packetization technique targeted toward eliminating negotiations between the network nodes prior to the change in the parameters of the transmitted signal on a packet-by-packet basis. We anticipate that after the completion of Phase II, Lexycom will be more than capable of delivering production-ready operational EVA SDR prototypes for further advancements in the transceiver's Technology Readiness Level (TRL). We strongly believe that such radio would facilitate flexibility, provide consistent functionality, and reduce implementation time for future NASA planetary explorations.
