The SETS Team will provide relevant subject matter expertise and system engineering support for the Radio Frequency Interference Monitoring System (RFIMS) Project.
Specific RFIMS support tasks include the following:
Radio Frequency Support
•Provide assistance in analyzing space to ground communications, including antennas, space contractor systems engineering, and RF analyses;
•Assist the OSGS RFIMS Project in developing a monitoring system architecture;
•Conduct RF link and spectrum interference analyses;
•Support Project in working with the National Telecommunications and Information Administration (NTIA), to perform RF related trade-off analysis and miscellaneous RF related technical studies;
•Provide site visits, when requested, to support RF environment surveys, assessments of potential vendor solutions which mitigate RF spectrum interference issues, and to support the establishment of a RFIMS testbed;
•Support development of solicitation documentation and provide technical evaluations in support of OSGS RFIMS solicitations.
•Additional RF Subject Matter Expertise (SME): Serves as the expert in RF systems engineering and analysis exhibiting an exceptional degree of ingenuity, creativity, and resourcefulness. The RF SME typically serves as the prime spokesperson to the customer on all RF spectrum sharing technologies to include: hardware and software, concept, design, fabrication, test, installation, operation, maintenance, sustainment and disposal. The RF SME performs duties such as site surveys, system evaluations and systems analyses including architecture and infrastructure assessments. The RF SME applies practice standards/best practices and develops advanced technologies, scientific principles, theories, and concepts in support of the development and fielding of RFIMS capabilities. The RF SME can act independently to resolve issues associated with the development and implementation of RF and communications systems. The RF SME provides expertise in developing and evaluating system design requirements and specifications, analysis, testing, integration, and documentation, and overall RF systems engineering and technical support to all aspects of the RFIMS project.
•Provides RF systems expertise and consulting services in the development and fielding of technologies to protect NOAA environmental satellite-to-ground communications systems from mobile wireless communications devices that are or will be sharing the 1695 MHz – 1710 MHz spectrum
•Performs technical planning, systems integration, verification and validation, cost and risk, and supportability and effectiveness analyses for complex RF and satellite communications systems to include mobile wireless devices and any associated interference phenomenology
•Supports the RFIMS Project Manager in monitoring and controlling the technical performance of the RFIMS development contract(s) throughout contract execution
•Conducts RF link analyses and RF spectrum interference analyses, assist in RF support with the National Telecommunications and Information Administration, perform RF trade-off and miscellaneous technical RF studies
•Provides site visits, as needed, to support the establishment of a RF systems testing capability, to conduct and/or support RF environmental surveys, and to observe testing of Contractors’ RFIMS technologies during contract execution
•Assesses and evaluates potential Contractor technology solutions designed and developed under the RFIMS acquisition effort to mitigate spectrum management and RF interference issues
•Supports reviews, evaluations and provides comments on all Contractor technical documentation and deliverables and supports key SDLC milestone reviews.
