The Argus$+$ Program: Next Generation Mapping.

Argus$+$ is a high-fidelity 3mm atmospheric window widefield mapping receiver. The plan is for the Green Bank Observatory's receiver to be general purpose to support the U.S. scientific community. Argus$+$ will have an angular resolution of 6.5'' -- 8'', the high sensitivity enabled by a filled aperture, and a wide field of view. This maps molecular clouds within hundreds of square arc-minutes with a spatial dynamic range (map area / pixel size) of 10$^{\mathrm{4}}$ to 10$^{\mathrm{5}}$. Based off the original 16-pixel Argus receiver commissioned in 2016, Argus$+$ will allow scientists to ask key science questions about star formation and astrophysics. Argus demonstrates unique scalable array technology that could be developed into Argus$+$'s 144-pixel camera. This technology combined with GBT metrology improvements commissioned in 2018 will increase the scientific output in the 3mm window by 20x. The team tasked with creating Argus$+$ will be the original Argus team and GBO staff for combined decades of experience designing, developing, and operating instruments for the U.S. science community. The APS poster poster shall display the science of the instrument, how systems engineering was implemented in the project, possible designs, and broader impact within the U.S. community. Using systems engineering and agile techniques, the requirements, processes, and matrices were modeled for technical design and development. The instrument provides an exploration of the tools to develop model-based processes as the use of Unified Modeling Language (UML) and Systems Modeling Language (SysML) for organizational models providing an opportunity for learning techniques for managing and defining technical projects. \textbf{Contact Information:} This is an APS poster abstract for the GBO REU program, roli9512@colorado.edu, 408-510-4658
