Applications beyond NASA include national and international universities, research institutes and government organizations involved in the full range of atmospheric and meteorological studies. All research and non-research groups that currently use dropsondes in their programs are potential consumers, as well as those that have interest in small UAS. Commercial applications are numerous in such fields as agriculture, surveillance, fisheries and coastal monitoring, particularly if the guided system is recoverable and has reduced regulatory issues. Military and homeland security are potential large-scale users of the proposed technology as it offers advantages in situational awareness and the ability to identify hazards without human risk or significant cost compared to conventional systems. Dropsondes have been employed to assist in validation of satellite data such as the NASA GloPac mission including measurements for the Aura earth-monitoring satellite. The proposed guided dropsonde system would provide increased utility in this type of application. Guided dropsondes could also be developed to have capabilities such as formation flying, opening even more research opportunity. The proposed design would be compatible with AVAPS systems currently used on NASA's P-3 and Global Hawk aircraft but versatile enough to be used with other platforms including balloon drops. Unmanned systems have numerous applications for research in polar regions where NASA balloon-based and airborne research is active.
