The government requires two unmanned aircraft systems (UAS). The listed components reference the Rohde & Schwarz AMS Aerial Monitoring System and associated UAS to establish a standard of quality, performance, and completeness, but are descriptive rather than restrictive. Offerors may propose equivalent products provided their solution meets all salient characteristics. Offerors proposing an “equal” solution are strongly encouraged to provide a point-by-point narrative explaining how their proposed system meets each salient characteristic.
