SBIR-STTR Award

The objective of this research is to propose a reliable, lightweight, programmable, multi-band, multi-mode, miniaturized frequency-agile EVA software defined radio (SDR) that supports data telemetry, voice, and high-rate video. The proposed radios would be a part of an advanced, incrementally expandable ad hoc wireless network. For improved reliability and to assure stand-alone functionality, the network would support a real-time 3D location function using mobile-assisted navigation and utilizing TOA/TDOA methods. To achieve unparalleled power consumption efficiency, Lexycom proposes the use of energy-aware packet routing and cognitive selection of operating point of the transceivers. Along with the scheduling, we plan to use an innovative RF packetization technique aimed to virtually obsolete negotiations between the network nodes prior to change in transmitted signal parameter on a packet-by-packet basis. We anticipate that after completion of the Phase I, Lexycom will be more than capable of delivering an operational prototype EVA SDR for further evaluation and enhancements of the chosen concepts and approaches. Since Lexycom Technologies is the manufacturer of an FCC certified, reconfigurable, small form factor and low power consumption SDRs, we are in an ideal position to transfer and expand our knowledge base from our existing radio platform over to the EVA radio.

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.
