Small unmanned aerial systems (sUAS) for civil remote sensing applications are becoming ubiquitous for scientific insight about targets such as micro-agriculture, invasive species monitoring, and environmental survey applications. For the upcoming generation of beyond visual-line-of-sight (BVLOS) capable sUAS, a flexible, robust, and high-performance payload management and data collection software is required. In this paper, a high-rate, accurate, multispectral, modular, payload control software (“AggieCap3”) for such BVLOS sUAS is described, including system requirements, architecture, implementation, and results from both fixed- and rotary-wing craft, demonstrating the systems applicability for civilian scientific aerial remote sensing.
