&lt;p&gt;A hyperspectral visible radiometer instrument system has been developed for use on UAS platforms.&amp;nbsp; It has been successfully flown on three previous UAS field campaigns, and recently integrated for flight on board MIZOPEX a fourth.&amp;nbsp; In all of these experiments, the radiometer was configured in a fixed-look scan angle mode that allowed for observing along a single fixed track, and the science data were recorded internally on board the UAS and only made available upon the successful return of the UAS and its payload.&amp;nbsp; The focus of this project is to expand upon the present UAS capability for observing hyperspectral reflectance spectra.&amp;nbsp; By integrating a scanning subsystem and a remote telemetry capability, we will enable science investigator(s) to modify the scanning configuration in order to optimize the science data collection in a specific region in the cross-track domain.&lt;/p&gt;&lt;p&gt;A hyperspectral radiometer instrumentation will be integrated into a scanning subsystem in order to allow the radiometer to scan across a range of angles as the UAV progresses along in its survey. &amp;nbsp;The configuration will consist of a series of lower spectral resolution radiometers that will be set to cross-track scan angles, a higher spectral resolution radiometer with a cosine collector set to zenith for measuring the downward radiance spectra, and a second higher resolution radiometer mounted to a servo motor for scanning along a cross-track scan angle that can either be preset or controlled remotely. &amp;nbsp;Real time spectral observations will be downscaled to send the spectra to a downlink computer in near real time.&amp;nbsp; These observations would then be available for re-tasking the scanning component of the radiometer.&lt;/p&gt;&lt;p&gt;The ability to collect reflectance spectra of the ocean surface in real time can help scientists optimize their data collection strategies.&amp;nbsp; Optimization of data collection has become a growing area of research, especially for scienctists who are faced with collecting science data in a regions that have small space and time scales of variability.&amp;nbsp; This problem is also one of concern for UAS-enabled science instruments that would prefer to set their observational focus as a function of the observed spatial variability, allowing more observations to be collected along features of interest and less within areas that show little variability.&amp;nbsp; Such observing strategies lend well to 2D spatial mapping algorithms such as optimal interpolation.&lt;/p&gt;&lt;p&gt;The present radiometer instruments and software is easily portable to a system configured with multiple radiometers.&amp;nbsp; The two major technical aspects of this project will be in regard to the control of the pointing system and with the real time data telemetry link.&lt;/p&gt;
